What are the requirements for the installation of heat-conducting oil boiler diesel burners?

The heat-conducting oil boiler diesel burner is a type of high-efficiency, energy-saving and environmentally friendly boiler diesel burner, and its current supply It is favored by consumers in the hot market. The installation of general heat-conducting oil boiler diesel combustion engine due to many auxiliary equipment, such as electrical control cabinet, induced draft fan, dust collector, oil storage tank, expansion tank, etc., will be more complicated in installation and debugging. So let's briefly explain below. The performance characteristics of the heat-conducting oil boiler diesel burner The heat-conducting oil boiler light oil burner has low pressure and high temperature working characteristics, and its heating temperature can reach 340℃ in liquid phase or 400℃ in vapor phase. Any process that requires uniform and stable heating and does not allow direct flame heating, where the heating temperature is between 150°C and 380°C, can be heated by organic heat transfer media. Oil and gas organic heat carrier furnaces use oil (gas) as fuel and heat transfer oil as the medium. The thermal oil circulating oil pump is used to force the medium to circulate in the liquid phase. The heat energy is transferred to the heating equipment and then returned to the heating furnace for reheating. High working temperature can be obtained under low pressure, and high-precision control of medium operation can be carried out. The heat utilization rate of the system is high. Because the module is installed as a whole, it is easy to operate and maintain. It is a safe and energy-saving ideal heating equipment. The fuel oil (gas) is ignited by the combustor and the high-temperature flame enters the inner coil to form a radiant heating surface. It rotates forward through the rear of the inner coil through 180° into the interlayer area of ​​the inner, middle and outer pipes to form a convective heating surface. Then enter the second interlayer area of ​​the middle and outer coils at the upper part of the interlayer, and exhaust into the atmosphere at the back of the second interlayer area to the chimney. 1. Obtain low-pressure and high-temperature heat medium, easy to adjust, uniform heating, and can meet accurate process temperature. 2. Liquid phase circulation heating, no heat loss due to condensation and high thermal efficiency of the heating system. 3. There are technical measures to compensate the volume changes caused by the heating and release of the working medium and the temperature rise and fall. 4. There are technical measures to strictly control the air, moisture and other low volatile content in the working medium before circulating heating. The organic heat carrier furnace is a new and special type. Classification of thermal oil boiler diesel burners According to the heat source conditions of boiler diesel burners, the types of thermal oil boiler diesel burners can be pided into direct fired boiler diesel burners, electric heating boiler diesel burners and waste heat recovery boiler diesel burners. 1. Directly fired heat transfer oil boiler diesel burner takes into account the characteristics of heat transfer oil, the directly fired boiler diesel burner is usually designed as a tube boiler diesel burner, that is, only the heating surface of the furnace tube is arranged in the boiler diesel burner. The heat transfer oil flows in the furnace tube and is heated. According to the characteristics of the fuel used, the combustion mode of the diesel burner of the directly fired boiler is different, so the structure of the diesel burner of this type of boiler is quite different. Most of the boiler diesel burners that use liquid or gas fuel are designed as a cylindrical furnace body. The furnace is composed of a cylindrical coil wound by the furnace tube to form a combustion chamber. The convective heating surface also adopts a cylindrical coil structure and is arranged On the outside of the combustion chamber, an annular flue gas channel is formed between the inner and outer coils. The diesel burners of coal-fired boilers are mostly chain grate boiler diesel burners. Due to the limitation of their combustion equipment, their furnace body structure still maintains the typical coal-fired chain boiler diesel burner type, but the radiant heating surface in the furnace is designed It is formed into an approximately rectangular coil type, and the convection heating surface adopts a dense serpentine coil group, which is still arranged in the flue at the rear of the furnace. 2. Electric heating heat transfer oil boiler diesel combustion Electromechanical heating heat transfer oil boiler diesel burner is a boiler diesel burner that uses electric heating elements as a heat source to heat the heat transfer oil, so the metal jacket surface of the electric heating element is the boiler diesel combustion The heating surface of the machine, the heat transfer oil is heated when it flows through the surface of the heating element. According to the nature of the heat transfer oil to be heated and its working form, electric heating boiler diesel burners can be pided into gas-phase boiler diesel burners and liquid-phase boiler diesel burners. Gas-phase boiler diesel burners are mostly designed as box or cylindrical containers. Most of the liquid-phase boiler diesel burners are designed as tubular or shell cylindrical vessels. 3. Waste heat recovery heat transfer oil boiler diesel burner waste heat recovery heat transfer oil boiler diesel burner water uses industrial waste heat as a heat source to heat the heat transfer oil boiler diesel burner, waste heat boiler diesel burner is mostly regarded as a shell-and-tube heat exchange According to the process conditions of the waste heat source, the heat transfer oil can flow in the tube or the shell, and it will be heated when it flows through the flue or container or pipe. The waste heat boiler diesel burner can also be a gas-phase boiler diesel burner or a liquid-phase boiler diesel burner. Introduction of auxiliary equipment of heat-conducting oil boiler diesel combustion engine The electrical control cabinet The electrical control cabinet is equipped with a powerful fault analysis function. When a fault occurs, the system can intelligently analyze the current fault, prompt the cause of the fault, and propose to eliminate the fault Method: The electrical control cabinet uses PID calculation rules to calculate the required heat load of the boiler diesel combustion engine and the output load of the burner, which improves the control accuracy while saving energy consumption and reducing the operating cost of the unit; load sensor signal universal input, It can be applied to thermocouple, thermal resistance, standard voltage, standard current, resistance signal and passive contact signal. It can carry out load control, alarm and display on the heat-conducting oil burner and light oil burner; touch control panel humanized design, touch sense It is strong, comfortable to handle, and has functions such as button sound, which improves the efficiency of buttons. It can realize automatic/manual/timed start-up and shutdown functions, and automatic/manual load adjustment functions; the electrical control cabinet can realize parameter setting, status management, password verification and historical fault inquiry through touch panel and color LCD screen. Machine dialogue function. Dust collector The dust collector has simple structure, metal consumption and small area, so the dust removal efficiency can reach more than 90%, so medium and small boiler diesel burners are used more. The disadvantage of the wet dust collector is that it consumes a lot of water, and the acid-containing wastewater needs to be treated to meet the discharge standard. The flue gas with water causes dust accumulation in the flue and induced draft fan impeller, causing corrosion and unbalanced quality of the induced draft fan (sonic dust cleaner) impeller And vibration. The dust gas is filtered through the filter bag, the dust is stored in the bag, the clean air enters the air purification room through the gas in the bag, and the air is discharged into the atmosphere through the fan. When the dust on the surface of the filter bag continues to increase, the program controller starts to work, and the pulse valves are opened one by one, so that the compressed air blows the dust through the nozzle, and the filter bag suddenly expands. Under the action of the backflow, the dust of the bag filter is quickly separated from the filter bag, falls into the ash bin, and the dust is discharged through the dust removal valve. Products have various specifications, filter area and air volume. To clarify the particle size distribution of dust. The particle size of dust is its basic characteristic. It is an aggregate composed of particles of various sizes. It is not enough to simply use the average particle size to characterize this aggregate. To find out the stickiness of dust. Viscosity is a characteristic of mutual attraction between dust or between dust and molecules on the surface of an object. For bag filter, the effect of viscosity is more prominent, because the dust removal efficiency and filter resistance largely depend on the ability to clean dust from the filter material. The induced draft fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Induced draft fans are widely used in ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boiler diesel burners and industrial furnaces; air conditioning equipment and household appliances Cooling and ventilating; drying and selective delivery of grain; inflating and propulsion of wind source in wind tunnel and hovercraft. The working principle of the induced draft fan of the heat-conducting oil furnace and the light oil burner is basically the same as that of the turbo compressor, but because the gas flow rate is low, the pressure changes little, and there is generally no need to consider the change of the gas specific volume. Expansion tank In the heat transfer oil heating system, the expansion tank is an operating device for the successful operation of the entire system. The improvement of the expansion tank is beneficial to prolong the life of the heat transfer oil and also indirectly protects the heater, hot oil pump and other equipment components. The expansion tank of the traditional heat-conducting oil furnace light oil burner has a fixed expansion of the reserved hot oil, and the capacity cannot be adjusted according to different working conditions; the support device of the expansion tank is a fixed device, which is not easy to match when installing the expansion tank The height of the expansion tank needs to be adjusted; the expansion tank has a large oil storage capacity and is easy to contact with air. Once in contact with air at high temperatures, it is easy to oxidize, resulting in rapid deterioration of oil, reduced heat transfer efficiency, oil change costs and operating costs Significant increase, so cooling the expansion tank is also an urgent problem to be solved. Oil storage tank The oil storage tank can also be called a low-level tank. The expansion tank is used as compensation for the volume change of the heat transfer oil due to temperature changes in the operation system of the heat transfer oil furnace light oil burner, thereby stabilizing the pressure of the heating medium of the system, and also helping The system is dehydrated and exhausted, so the expansion tank should be set at an elevation of 1.5-2M higher than other equipment or pipelines in the system, and the high liquid level should be maintained during normal operation. When there is a sudden power failure or a failure of the hot oil circulation pump and an emergency shutdown is required, the cold oil replacement valve can be opened. At this time, the cold oil in the high tank uses its potential to flow through the furnace tube and enters the oil storage tank, thereby preventing heat conduction in the furnace tube The oil is overheated. Oil storage tank (low tank) The oil storage tank is mainly used to store the heat transfer oil discharged from the high tank, furnace tube and the system. It should be in a low level state when working, ready to receive external heat transfer oil at any time. The exhaust port should be connected to a safe area and no valve should be installed. Equipment installation of heat-conducting oil boiler diesel burner The installation of the heat-conducting oil boiler diesel burner should ensure that the chimney flange connection surface is flat and connected with bolts. The connection surface is sealed with asbestos rope to ensure the tightness of the flue. 1. The method of aligning the backrest wheel: Put the side of the flat ruler on the outer circle of the motor and the backrest wheel of the water pump to check whether they are flat to adjust the center line of the pump shaft and the motor shaft in a straight line. 2. Test run of the water pump section: close the outlet pipe valve, pour water into the pump head to remove the air in the pump, and then turn on the motor. When the speed reaches the normal speed, open the valve on the outlet pipe to send water normally. (Requires stable operation, temperature rise and water head pressure meet the requirements to be qualified) Distribution cabinet installation The distribution cabinet is installed and debugged according to the factory design, and the auxiliary circuit of the heat-conducting oil boiler diesel combustion engine should be wired according to the motor power and requirements No overload, no heat, no winding. Water pipeline valve installation 1. The pipeline valve instrument is installed according to the figure. For those equipped with an electric pump, connect the electric pump and start the installation based on it. 2. The safety valve should be installed after the commissioning is qualified, and the safety valve exhaust pipe should be led to an outdoor safe place. 3. The sewage pipe is connected to the sewage tank or other safe place, and the pipe is fixed to prevent the displacement of the oil-fired gas boiler and diesel burner during sewage discharge. Instrument installation 1. Installation of platinum thermal resistance: When installing, try to avoid errors caused by heat radiation or heat conduction. You must choose a place that is in good contact with the measured medium and can accurately measure the temperature of the measured medium, that is, it should be inserted in the medium The area where the flow velocity is large and can be aligned with the centerline of the medium stream. 2. Installation of the bimetal thermometer: The bimetal thermometer should be installed in a place where there is no vibration, the insertion depth should be greater than 1/2 pipe diameter, and it is easy to observe and maintain. 3. Installation of pressure gauge: a buffer tube should be added between the pressure gauge and the measuring pipeline. On a vertical pipeline, the pressure point should be selected on the downstream section of the medium; on a horizontal pipeline, the pressure point should be selected at the lower part of the pipeline and within 45 degrees on both sides of the center line, but not at the lowest point of the pipeline . Before installation, the pressure gauge should be checked by the local measurement department, and the next check date should be indicated, and it should be sealed after the check. A red line should be drawn on the pressure gauge dial to indicate the maximum allowable working pressure of the boiler diesel burner. 4. When the total injection volume of the boiler diesel combustion engine and the organic heat carrier in the system is greater than 5 cubic meters, safety protection devices should be installed in accordance with the requirements of TSG G0001-2012 'Safety Technical Supervision Regulations for Boiler Diesel Combustion Engines' 11.3.6.2 ~ 11.3.6.6 . 5.
