How to deal with the power consumption of the diesel burner of the electric heating heat transfer oil boiler?

With the increasing emphasis on safe and environmentally friendly production in China, more and more customers have begun to choose to use electric heating heat transfer oil boiler diesel combustion engines to replace the traditional heavy pollution steam boiler diesel combustion The use of the machine. It transfers heat through heat-conducting oil, the heat loss is small during the conduction process, and the operation safety of the boiler diesel burner is high, so it is very popular among consumers. So if you find that the power consumption of the thermal oil boiler is too large, how should we deal with it? To understand the power consumption of the oil furnace, we must first know the two components of the oil furnace’s electricity consumption: the circulating oil pump and the heating tube. We use the 60kw heat conduction oil furnace light oil burner Configure a 505kw circulating oil pump to reach the target temperature in one hour, and work for 12 hours as an example to calculate the power consumption. 1. Full power heating: power consumption = 60×1=60 degrees; 2. Constant temperature for 12 hours: because the oil furnace adopts a circulating heating method, the waste heat can be fully utilized, so the heating power after the cycle is turned on is only required. Reach about 30% of the full power (the actual situation is related to the working environment temperature, the efficiency of the heating tube, the heat dissipation, etc.). Electricity consumption=60×30%×12=216 degrees; 3. Continuous operation of the oil pump: Electricity consumption=5.5×12=66 degrees. Therefore, we can calculate that the electricity consumption of a 60kw oil pump for 12 hours is about 350 degrees. Factors affecting the power consumption of the diesel burner of the electric heating heat transfer oil boiler There are two main power consumption components of the electric heating heat transfer oil boiler light oil burner, one is the electric heating tube, and the other is the circulating pump. During the use of the electric heating heat-conducting oil furnace light oil burner, after setting the temperature required by a certain process, the electric heating heat-conducting oil furnace light oil burner will be running all the time, which will consume more electric energy. After reaching the temperature, the heating part of the heat-conducting oil furnace and light oil burner in the later normal production only plays a role in temperature adjustment, and the power consumption will be greatly reduced. If the electric heating heat conduction oil burner light oil burner consumes too much electricity, there may be the following reasons! Factors that affect the efficiency of the heating tube Electric heating heat conduction oil furnace light oil burners mostly use plug-in electric heating tubes, which are magnesium oxide powder filled with alloy resistance wires. 1. The purity of magnesium oxide powder: The purity of magnesium oxide directly determines the thermal conductivity of magnesia. The larger the thermal conductivity, the smaller the thermal resistance. The higher the heat transfer efficiency. 2. Magnesium oxide powder filling density: The density is determined by the filling density, shrinking tube or shaping density to determine the final density of the electric heating tube. The greater the density value, the higher the electric heating efficiency, and vice versa. 3. The material of the electric heating tube: the material with good thermal conductivity is used, which has a certain promotion effect on improving the efficiency of electric heating and improving the performance and life of the electric heating tube. Circulation pump power selection Circulation system, as an important part of the light oil burner of the electric heating heat transfer oil furnace, also takes up a certain amount of power consumption. Its power consumption is also a problem that many people easily overlook. The power of the circulating pump should consider factors such as pipe diameter, length, pressure, etc., and calculate and select the type to ensure the best flow rate when the electric heating heat conduction oil burner light oil burner is used in conjunction with the heating equipment. In the industry, some manufacturers of electric heating heat conduction oil burner light oil burners, for the sake of 'safety', directly choose higher-power circulating pumps for customers without calculation. For example, 5KW is sufficient, but 10KW is used. If the light oil burner of the electric heating heat conduction oil furnace works 12 hours a day, 60 kWh of electricity will be wasted a day. Too much carbon deposit 1. Prevent carbon deposit in heat transfer oil: if the temperature of heat transfer oil is too high, it will be carbonized. The surface temperature of the heating tube is very high. If the flow rate of the heat transfer oil in the heating tube is too low, it will cause the local temperature of the heat transfer oil on the surface of the heating tube to be too high and form carbon deposits. 2. When the light oil burner of the electric heating heat conduction oil furnace stops working, the temperature should be lowered to normal temperature first to avoid high temperature shutdown. Because the surface of the heating tube is still at a high temperature at the moment of shutdown at a high temperature, the heat transfer oil in the heating tube stops flowing, which will cause the local temperature of the heat transfer oil on the surface of the heating tube to be too high and form carbon deposits. 3. Generally, the heat transfer oil that has been used for more than half a year should be replaced and cleaned of grease on the surface of the heating tube. This is also a way to improve the efficiency of the light oil burner of the electric heating heat transfer oil furnace. How to clean the heat-conducting oil boiler diesel burner 1. Drain the system oil: Circulate heat-conducting oil to drain the heat-conducting oil in the system between 120±5℃, if you don’t change the oil, please find a clean container for storage, and then prepare an appropriate amount The heat transfer oil system removes the coke cleaning agent, and drains the oil in the heat transfer oil system. At the same time, the cleaning system is disconnected from the oil storage tank, and the connection between the high tank and the oil storage tank is also included. 2. Blowing residual oil step: connect the air compressor at the pressure gauge or other connectable places, increase the pressure of the system to 0.3-0.4MPa, and discharge instantly; repeat this operation until the residual oil is blown out , And the heat-conducting oil furnace light oil burner, circulation pump and other heat exchangers form a cleaning circulation loop. 3. Decoking cleaning: After the above steps are completed, if you want to add the diluted cleaning agent to the system, when it is filled to one-half of the water level of the high tank, add an appropriate amount of decoking cleaning agent, almost 10% To 20%, we need to determine the specific dosage based on the scale thickness. The temperature is between 90 and 95 degrees Celsius, and the time should be determined according to the scale thickness, which is between 12 and 72 hours. 4. Rinsing and cleaning: After cleaning, we have to clean up the remaining night in the drainage system and add water to rinse until the coke cleaning agent has no foam and the water is clear. 5. Blowing steps: connect the air compressor at the pressure gauge or other connectable places, use compressed air to boost the system to 0.3-0.4MPa, and vent at each low point, and repeat until the water is blown out until. 6. Waste liquid treatment. During the cleaning process of the thermal oil boiler diesel burner, cleaning waste liquid will be generated, which will be discharged after being processed in the biochemical tank. The characteristics of thermal oil boiler diesel burner cleaning agent The thermal oil coking and carbon deposit cleaning agent can quickly and safely dissolve the coking and carbon deposits of various heat transfer oils, and dissolve the coal tar coke scale into liquid. Thermal oil coking and carbon deposit cleaning agent is a green, environmentally friendly, fast and safe decoking cleaning agent. It is made up of a variety of imported surfactants and organic additives. It has excellent permeability, emulsification and oil removal. Ability to remove coking and carbon deposits of heat transfer oil, unlimited application range, non-flammable. The thermal oil coking and carbon deposit cleaning agent does not corrode or damage all kinds of common carbon steel, stainless steel, copper, iron and other metals. Its main cleaning principle is to rely on the action of the penetrant to make the cleaning agent quickly penetrate into the coke scale layer, and through a special chemical action to decompose the insoluble scale of large molecules into the oily structure of small molecules, so that the penetrant and emulsification Under the action of the agent, the small molecule grease is incorporated into the cleaning agent, and the grease is removed with the physical action such as the circulation of the cleaning agent (for rubber and plastic parts that are not resistant to solvents, it is not appropriate to soak in the cleaning agent for a long time). Precautions when switching the feedwater pump of the heat-conducting oil boiler diesel combustion engine The pump wheel and turbine of the boiler diesel combustion engine feedwater pump are working wheels with straight-diameter blades, the pump wheel is fixedly connected to the driving shaft, and the turbine is fixedly connected to the driven wheel; The driving wheel and the driven wheel are respectively connected with the motor and the pump; the pump wheel and the turbine have no fixed parts, they are arranged oppositely and the two end faces maintain a certain gap. A circular cavity is formed between the pump wheel and the turbine to become a working cavity. If the working chamber is filled with working medium such as oil, when the drive shaft rotates with the pump wheel at high speed, the blades on the pump wheel of the boiler diesel burner feed water pump drive the working oil to rotate at high speed. The high speed oil rotating at high speed is affected by the inertial centrifugal force. Under the action, it is thrown to the outer circumference of the pump wheel to form a high-speed oil flow, which rushes into the inlet radial flow passage of the turbine. Along the radial flow passage, the power torque of the working oil drives the turbine to rotate, and at the outlet of the turbine, Enter the radial flow channel of the pump wheel at the combined speed of the radial relative speed and the turbine outlet speed, and regain energy from the pump wheel. The cycle starts again. The pump wheel converts the mechanical energy of the prime mover into the kinetic energy and pressure potential energy of the working oil. The working oil of the turbine converts the mechanical energy into the mechanical energy of the output shaft and transmits it to the pump, thereby realizing the flexible transmission of the motor shaft power. The following problems should be paid attention to when the feed water pump of the boiler diesel combustion engine is switched. 1. The scoop tube of the boiler diesel burner feed water pump should be added or subtracted slowly, not too fast. 2. It is best to start the auxiliary oil pump before stopping the feed water pump to prevent the auxiliary oil pump from malfunctioning. 3. For the newly-started feedwater pump, pay attention to the temperature rise of the bearing and motor. If the temperature rises too fast or is higher than another feedwater pump, stop the switching operation and find out the cause. 4. If the steam drum feedwater regulating valve is abnormal or the drum water level fluctuates drastically during the switching process, the operation should be stopped and the previous operating state should be restored. 5. After the switch of the feed water pump of the boiler diesel combustion engine is completed, the standby pump should not be shut down too quickly, and the newly running pump should be checked for leaks and other abnormalities. Precautions for heating up the organic heat carrier of the thermal oil boiler diesel burner 1. The heating process of organic heating medium ignition should be carried out strictly according to the heating curve (or according to the heating curve provided by the heat carrier furnace manufacturer). 2. When the temperature of the organic heating medium rises above 200°C, a comprehensive inspection of the equipment and the entire system should be carried out, and all bolt connections should be tightened once to eliminate leakage caused by thermal expansion. 3. Pay attention to the expansion of organic heating medium. When it is lower than 100℃, it is about 6%; when it is 100~200℃, it is about 7%, and when it is 200~300℃, it is about 7.5%. If the liquid level of the expansion tank is too high, the discharge pipe should be opened, and the heat carrier should be put into the low-level storage tank to avoid a large amount of heat carrier overflow from the high-level tank and cause accidents. 4. The circulation pump must be turned on before the ignition of the organic heating medium cold furnace. In northern cold areas, the heat carrier should be heated and melted with steam before ignition, and then the circulation pump can be started. 5. The moisture removed during the ignition and heating process of the organic heating medium liquid phase furnace is passed into the expansion tank through the expansion tube in the form of water vapor, part of which is discharged from the exhaust pipe as gas, and the other part is condensed into water and sinks at the bottom of the tank. To prevent this moisture from entering the circulation system again, the drain pipe at the bottom of the expansion tank must be opened regularly to release the condensed water during the heating process. Thermal oil boiler diesel burner temperature measuring resistor is damaged Once the temperature measuring resistor in the light oil burner of the thermal oil boiler is damaged, the usual solution is to increase the spare parts of the light oil burner of the electric thermal oil furnace. Method, that is to say, turning the diameter of the temperature measuring resistor in the light oil burner of the electric heat conduction oil furnace, and increase the shaft sleeve in the light oil burner of the electric heat conduction oil furnace. The inner hole of the light oil burner of the electric heat conduction oil furnace has been used. The full fit method is matched with the heat conduction shaft of the light oil burner of the electric heat conduction oil furnace, so that the outer surface of the light oil burner of the electric heat conduction oil furnace meets and matches the size required by the temperature measuring resistor in the light oil burner of the electric heat conduction oil furnace . The rotor shaft of the temperature measuring resistor in the light oil burner of the electric heat conduction oil furnace can also be replaced to completely solve the problem of the temperature measuring resistor in the light oil burner of the electric heat conduction oil furnace.

When adding heat transfer oil to the light oil burner of the electric heat transfer oil furnace, it is recommended that the minimum liquid level of the controller in the heat transfer oil in the light oil burner of the electric heat transfer oil furnace should be higher than that of the electric heat transfer oil The surface of the heat transfer oil pump in the furnace light oil burner is 150mm. Similarly, the position in the light oil burner of the electric heat conduction oil furnace should be 100mm higher than the lowest temperature resistance in the light oil burner of the electric heat conduction oil furnace. Effectively improving the thermal efficiency of heat-conducting oil boiler diesel burners is a problem that many users consider. I believe this problem is the direction that every manufacturer of heat-conducting oil boiler diesel burners has been researching in production. Many users often find some new problems in the actual production process when operating the light oil burner of the heat-conducting oil boiler, but among all the problems, the most troublesome is the exhaust of the heat-conducting oil boiler diesel burner. The phenomenon of high smoke temperature and low thermal efficiency, this phenomenon seriously affects our normal work, so what should we do to improve its thermal efficiency? What needs to be understood is that the synthesis that can best meet the low temperature characteristics of heat transfer oil is Type heat transfer oil. However, most synthetic heat transfer oils are biphenyls, which are benzene derivatives with complex components, and their vapor or volatiles are highly carcinogenic. Therefore, it is strongly recommended that customers choose mineral oil heat transfer oil products. Secondly, thermal oil products must have relatively high flash point requirements while meeting low temperature performance. Under normal circumstances, the thermal oil engineer recommends that the flash point of the low-temperature thermal oil opening should not be lower than 200°C. After continuous research and improvement of its equipment by professional manufacturers, it is found that in order to improve its thermal efficiency, it is necessary to increase the heating surface of the tail of the thermal oil boiler diesel burner, such as air preheater and economizer. However, when the return temperature of the organic heat carrier furnace body is high, the economizer cannot be installed, and only an air preheater can be installed to alleviate the situation. Therefore, if the thermal oil boiler diesel burner does not exchange heat with other low-temperature heating systems, the only way to improve energy efficiency is to add an air preheater. After adding an air preheater, the flow rate of the heat transfer oil can be increased accordingly to ensure the safe, reliable and stable operation of the heat transfer oil boiler diesel burner, and the thermal efficiency of the heat transfer oil boiler diesel burner equipment will also increase accordingly. Measures to effectively reduce the heat loss of the heat transfer oil boiler diesel burner 1. Automatic temperature control heat transfer oil burner light oil burner, especially in the case of small temperature control intervals and low temperature, the amount of induced air should be adjusted first. In the case of positive pressure combustion, a part of the inlet of the blower can be blocked, and the air volume of the blower should be adjusted to the required temperature as much as possible, and the number of openings of the blower can be reduced as much as possible to reduce our power loss. 2. The hot oil circulating pump must be started before the light oil burner of the heat-conducting oil furnace is ignited or heated to prevent the heat-conducting oil from overheating and coking and burning out. 3. It is normal for the condensed water to flow out of the boiler diesel burner with refractory cement pouring and insulation materials during the drying period. Especially the connection between the upper and lower body of the light oil burner of the vertical heat transfer oil furnace and the ash removal port may be mistaken for oil leakage from the diesel burner of the boiler. At this time, the outflow liquid can be dripped into the water for identification, if it can be dissolved Water is condensed water or heat transfer oil. 4. The light oil burner of the horizontal heat-conducting oil furnace is separated from the factory, and the customer must ensure the temperature insulation of all headers in the lower part during the second pouring after assembly. The insufficient output of the heat-conducting oil burner and the light oil burner after a period of use is generally caused by the failure to clean the dust in time. When cleaning, pay special attention to whether there is too much dust in the dust collector. Water can be discharged cannot prove that there is no dust in the dust collector. . 5. After the dehydration and exhaust of the heat-conducting oil burner and the light oil burner are completed, be sure to close the auxiliary exhaust valve and open the exhaust port of the high slot. (Note that before dehydration and exhaust, the exhaust ports of the high and low tanks should be connected to a safe position.) 6. If the pressure of the light oil burner of the heat-conducting oil furnace is too low during the commissioning stage, there may be too many impurities in the system. If the filter is blocked, the filter should be cleaned before debugging. 7. During the installation and commissioning process of the heat-conducting oil furnace light oil burner system, the high position tank and the position tank will not participate in the pressure test.
