Factors affecting the power consumption of the thermal oil boiler diesel burner

In recent years, as environmental protection efforts across the country continue to increase, the heating equipment of many enterprises The traditional steam boiler diesel burner is replaced with a more energy-saving and environmentally friendly heat transfer oil boiler diesel burner. It transfers heat to the heating equipment through the heat transfer oil, which greatly reduces the heat loss during the transfer process, so it has attracted much attention in the current heating market. So what factors usually affect the power consumption of the heat-conducting oil furnace light oil burner? Let's briefly explain below. Calculation of the power consumption of the heat-conducting oil boiler diesel burner. Take the 100KW electric heating heat-conducting oil burner light oil burner as an example. The pump power is 5KW, reaches the set temperature in 1 hour, and runs for 12 hours a day. 1. Heating and heating: 100 kWh of electricity consumption for 1 hour at full power 2. Constant temperature: maintaining temperature balance, electric heating heat conduction oil furnace light oil burner heating tube works intermittently, usually accounting for 30% of the total power, electricity consumption per hour 30KW, this data is related to the heating tube efficiency, use environment, and heat dissipation conditions. The greater the heat dissipation, the greater the actual power consumption. 3. Circulating pump: The power of the pump is 5KW, and the power consumption is 60 kWh for 12 hours. It can be calculated that the daily power consumption of the light oil burner of the electric heating heat transfer oil furnace is 520 kWh. According to the actual electricity price, the daily power consumption cost can be basically calculated. From the above calculations, it can be seen that if the electric heating heat conduction oil furnace light oil burner needs to save electricity, it can be solved in three ways: 1. Improve the efficiency of the heating tube, reduce the heating time 2. Reduce heat dissipation and avoid heat waste 3. , Minimize the power of the circulating pump. There are two main power consumption components of the electric heating heat conduction oil burner 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! The general reasons for the power consumption of the thermal oil boiler diesel burner 1. The power is too large. If the power of the electric heating boiler diesel burner is too high and the temperature setting is too high, it will cause the boiler diesel burner to operate properly, which will increase the power consumption. If necessary, we should not set the temperature too high. 2. The quality of the electric heating unit The electric boiler diesel combustion engine is heated by the thermal resistance of the motor for heat conversion. If the inferior electric heating unit is used, the thermal efficiency will be reduced, the electricity will increase, and the electricity will be wasted. 3. Excessive temperature difference. Excessive temperature difference will also cause excessive waste of electricity. For example, in winter, the external temperature decreases, and when the space area of ​​the boiler diesel burner is large, it is easy to cause excessive heat dissipation of the boiler diesel burner , Resulting in unnecessary waste of heat, so the space of the boiler diesel combustion engine room should not be too large. Measures to improve the thermal efficiency of the thermal oil boiler diesel combustion engine 1. Use flue gas waste heat recovery technology to reduce flue gas loss. The main factor that affects the heat loss of exhaust gas is exhaust gas temperature. The higher the exhaust temperature, the greater the exhaust heat loss. Most of the current heat transfer oil boiler diesel burners are equipped with flue gas waste heat recovery devices when they leave the factory, such as economizers or fully condensed flue gas waste heat recovery devices. These measures can effectively reduce the exhaust gas temperature and increase the light oil combustion of the heat transfer oil furnace. The thermal efficiency of the machine. 2. Reasonably control air-fuel ratio, optimize combustion, and reduce incomplete combustion loss and exhaust heat loss. When the excess air coefficient is too high, it is equivalent to sucking in excess cold air into the furnace. This part of the excess cold air does not participate in the combustion, but is discharged in vain after being heated, and the heat loss of exhaust smoke increases; such as cold air entering the furnace If it continues to increase and exceeds a certain limit, the furnace temperature will decrease and the loss of incomplete combustion will increase. When the excess air coefficient is too low, the fuel cannot get enough oxygen and cannot be combusted completely, resulting in increased incomplete combustion loss. Long-term severe incomplete combustion will lead to carbon in the heated area of ​​the boiler diesel burner, which will affect the heat exchange efficiency and continue to increase the exhaust smoke loss. Therefore, reasonable control of the air-fuel ratio to minimize the exhaust heat loss q2 and incomplete combustion loss q3 is another key point for improving the thermal efficiency of the thermal oil boiler diesel burner. 3. Strengthen heat preservation, prevent leakage and reduce heat loss. Since the temperature of the heat transfer oil boiler diesel combustion engine body and the heat transfer oil thermal pipeline system is always higher than the air temperature in the boiler diesel combustion engine room, part of the heat will be dissipated to the surrounding air by radiation and convection, which becomes the heat dissipation of the heat transfer oil boiler diesel combustion engine loss. Therefore, when the thermal insulation layer of the heat-conducting oil boiler diesel combustion engine and the heat-conducting oil thermal pipeline system is damaged or leaks are found, it should be repaired in time to reduce heat loss. The cleaning method of the heat-conducting oil boiler diesel burner 1. The system oil-discharging circulating heat-conducting oil can be discharged between 120±5℃. If you do not change the oil, please find a clean container and store it properly. Prepare an appropriate amount of coke cleaning agent for the heat transfer oil system, drain the oil in the light oil burner system of the heat transfer oil furnace, and disconnect the cleaning system from the oil storage tank (close the valve), including the connection of the high tank and the oil storage tank. Disconnect. 2. On weekdays, the flash point and acid value of the oil should be checked and tested regularly. If the index is exceeded, the carbon deposit should be cleaned immediately to avoid the explosion of the boiler diesel combustion engine with excessive carbon deposits, which will affect the boiler diesel combustion engine. life. 3. Regularly use cleaning agents for online cleaning. This method is energy-saving and environmentally friendly, and can meet the cleaning tasks of small and medium-sized enterprises in the normal production process. This is also a more popular cleaning method at present. 4. When the boiler diesel burner is not used, all the heat transfer oil inside needs to be discharged, because if there is oil, the quality will change. If a leakage accident occurs, it will affect the surrounding environment. After releasing it It is necessary to clean the inside of the boiler diesel burner to keep the inside clean and avoid other impurities from appearing inside. 5. Regularly check the various parts of the gas heat conduction oil burner light oil burner to see if there is any looseness. After maintenance, the boiler diesel burner can be stored, and it can be used directly when it is used next time. There are other problems. Chemical cleaning should be carried out in time for the boiler diesel burner and circulation system whose heat transfer oil has been deteriorated or seriously polluted. This is an important measure to ensure the safety, energy saving and economic operation of the heat transfer oil boiler diesel burner. Precautions for the operation of the heat-conducting oil boiler diesel burner 1. The operator of the heat-conducting oil boiler light oil burner should be trained in the knowledge of the electric heat transfer oil boiler light oil burner and be assessed by the local boiler diesel burner safety supervision agency Issuance. 2. Units using heat-conducting oil furnace light oil burners must formulate operating procedures for electric heat-conducting oil furnace light oil burners. The operating procedures shall include the operation methods and precautions for starting, operating, shutting down, and emergency shutting down the light oil burner of the electric heat conduction oil furnace. Operators must operate in accordance with operating procedures.　3. The pipes within the range of the heat transfer oil furnace and light oil burner should be insulated, but the flange joints should not be covered.　4. During the heating process of the heat-conducting oil furnace light oil burner, the exhaust valve of the expansion tank should be opened to exhaust air, water and organic heat carrier mixed steam before it can enter normal operation. 5. The heat-conducting oil furnace and light oil burner can only be used after dehydration. Different organic heat carriers should not be mixed. When mixing is required, the organic heat carrier production unit shall provide the mixing conditions and requirements before mixing. 6. The light oil burner of the heat transfer oil furnace in use should be analyzed annually for its residual carbon, acid value, viscosity, and flash point. When two of the analyses are unqualified or the content of the heat carrier decomposition component exceeds 10%, it should be replaced Heat carrier or regenerate the heat carrier. 7. The heating surface of the light oil burner of the heat conduction oil furnace should be inspected and cleaned regularly, and the inspection and cleaning conditions should be stored in the boiler diesel burner technical file. 8. After the installation or major repair of the light oil burner of the heat-conducting oil furnace, the user and the installation or repair unit should conduct a hydraulic test of 1.5 times the working pressure before putting it into operation. During the hydraulic test and air tightness test, the local boiler diesel burner safety supervision agency should send people to participate. 9. The heat-conducting oil furnace, light oil burner, boiler diesel combustion engine room should have effective fire prevention and extinguishing measures. Precautions for the purchase of heat transfer oil 1. Confirm the authenticity of the highest use temperature of the heat transfer oil-test at the highest use temperature to see if the appearance is transparent, without suspended matter and precipitation, and the total deterioration rate is not greater than 10% corresponding to the temperature . 2. Confirm the evaporability and safety of the heat transfer oil-the flash point of the opening meets the requirements of the standard index. The higher the initial boiling point temperature, the less likely the heat transfer oil will vaporize, the more balanced the system temperature and pressure, and the smaller the supplement of heat transfer oil. The longer the life span; the heat transfer oil with high spontaneous ignition point is less likely to catch fire when exposed to air, and its safety is higher. 3. Confirm the depth of heat transfer oil processing and refining-the appearance is a light yellow transparent liquid, with good storage stability, and does not change color or precipitate after exposure to light. The residual carbon is not more than 0.1%, and the sulfur content is not more than 0.2%. 4. Confirm the low temperature fluidity of the heat transfer oil-select the appropriate low temperature performance according to the area where the heat transfer oil is used and the ambient temperature of the equipment. The kinematic viscosity at low temperatures (0°C or lower) is relatively low. Confirm the heat transfer performance of heat transfer oil-with lower viscosity and higher density, the smaller the temperature difference between the outlet temperature of the oil furnace and the operating temperature of the equipment, the faster the flow rate of the heat transfer oil, and the better the heat transfer performance of the heat transfer oil. The characteristics of high-quality heat transfer oil 1. The most important performance of thermal stability and heat transfer fluid. The thermal stability is different, the degree of thermal cracking and polymerization is also different in its use. Thermal cracking produces low-molecular low-boiling substances, which is easy to cause gas resistance in the system, causing cavitation in the pump, and also causes higher evaporation loss and environmental pollution of oil products; thermal polymerization produces high-molecular-weight high-boiling substances, which are gradually deposited on The carbon deposits formed on the surface of heaters and pipelines will affect the heat transfer efficiency and temperature control accuracy of the system. The heat transfer fluid selects base oils and additives with excellent thermal stability, so the product has excellent thermal stability; 2. Oxidation stability heat transfer fluid is another important performance. The open system or expansion tank does not use a nitrogen closed system, and the interface between the oil and the air will undergo oxidation. Generally speaking, when the temperature is higher than 60℃, the oil will be oxidized when it comes into contact with the air, and the oxidation products will gradually form colloids and sludge, which will adhere to the heater and pipeline surface and cause carbon deposition. At the same time, the acid produced by the oxidation reaction will corrode the equipment and cause leakage. The heat transfer fluid selects base oils with excellent oxidation resistance and high-temperature antioxidants and anti-scaling additives, which can inhibit the speed of oxidized sludge generation and the tendency of deposition and scaling, so that the system maintains a good heat transfer effect; 3. Low volatility The heat transfer fluid uses the initial boiling point to indicate its volatility. For the heat transfer fluid used in the open heating system, if the initial boiling point is lower than the operating temperature, it is easy to cause cavitation in the pump, the operating system will generate air resistance, and cause excessive evaporation loss. The higher initial boiling point of the heat transfer fluid makes it have very low vapor pressure and volatilization loss, which can ensure the smooth operation of the system; 4. Better safety The flash point and spontaneous ignition point of the heat transfer fluid indicate its safety. The flash point is used to indicate the safety performance of the heat carrier in a closed cycle system, and the spontaneous ignition point can predict the tendency of the heat transfer fluid to spontaneously ignite in the air when it leaks under high temperature conditions. The heat transfer fluid has a high flash point and self-ignition point, which can ensure the safety of system operation; 5. Heat transfer performance The heat transfer fluid not only has high thermal stability, but also has excellent heat transfer performance. Proper viscosity can provide higher cycle efficiency; higher specific heat and thermal conductivity can effectively transfer or absorb heat, improve fuel economy and operating efficiency. !
