Brief description of low nitrogen burner of heat transfer oil furnace
The heat transfer oil furnace is also called organic heat carrier furnace, commonly known as heat transfer oil boiler, and officially known as hot oil furnace. It is a new type of thermal energy equipment that uses coal, oil and gas as fuel and heat transfer oil as circulating medium for heating. The heat transfer oil furnace refers to a new type of thermal energy conversion equipment whose heat transfer working medium is high temperature heat transfer oil (also known as thermal coal and heat carrier). The advantages of the heat transfer oil furnace are "high temperature and low pressure", stable operation and widely used.
The domestic environment-friendly ultra-low nitrogen heat transfer oil furnace burner discharges less than 30mg/L, and uses methanol and natural gas as fuel to provide efficient heat energy for the heat transfer oil boiler. In addition, the ultra-low nitrogen burner adopts a unique structural design, which makes the flue gas generated in the combustion process form a forced reflux near the furnace, stabilizes the flame, reduces the oxygen concentration, and reduces NOx emissions. At present, low nitrogen burners are mainly used for the transformation of various oil refining heating furnaces, large steam boilers and coal-fired boilers. Heat transfer oil, also known as organic heat carrier or heat medium oil, has a history of more than 50 years in the process of industrial heat transfer. The burner of heat transfer oil furnace generally uses coal, oil and gas as fuel and heat transfer oil as medium. The hot oil circulation pump is used to force the medium to carry out liquid phase circulation, return the heat energy to the heating furnace for heating, and obtain high operating temperature under low pressure, which can control the operation of the medium with high accuracy. Most burners of gas-fired heat transfer oil boilers are imported. The imported low nitrogen burners are fully combusted and are environmentally friendly products. Ultra-low nitrogen burner: when the boiler outlet oil temperature is lower than the set outlet oil temperature limit, the inlet oil temperature is normal, and the inlet and outlet oil pressure difference is normal, and the boiler outlet oil temperature is higher than the set upper outlet oil temperature limit of - 5 ℃, turn off the two sections of the burner, so that the boiler outlet oil temperature value of the first section of fire is higher than the set upper outlet oil temperature limit, turn off the alarm of the first section of fire and the inlet burner of the two sections of fire of the burner, and immediately turn off the boiler burner. The supply of natural gas is mainly natural gas. The main functions of the refrigerator are the refrigerator and the control room. The function of the burner is to check the ignition, adjust the proportion of fuel oil and air, and control the opening of the burner according to the load. Air preheater is a device that uses exhaust gas to heat the flue gas.
The environmental protection standard for the low nitrogen burner of the thermal conductivity oil industrial boiler requires that the emission of the boiler is less than 30 mg, which overcomes the offensive of atmospheric management, promotes the technological progress of the energy utilization industry and the sustainable development of society, and improves the quality of the ecological environment. Europa, a domestic ultra-low nitrogen burner, is welcomed by many domestic enterprises. It has developed a low nitrogen burner with stable operation performance, complete safety logic, low pollutant emission and high integration. The main system and structural feature of this burner is the integrated design of the burner control system and the burner body. The control system is centered on the professional combustion program control system to meet the needs of users' equipment for highly integrated, automatic and low maintenance of the burner system. Medium and small thermal energy equipment generally includes medium and small industrial boilers, such as hot water boilers, steam boilers, heat transfer oil heating furnaces and other heating medium equipment below 8 MW; It also includes general production heating technology in the field of food thermal processing, hot-air stove, baking equipment, etc. Some process equipment such as incinerator and paint tail gas treatment. Europa, a domestic brand, has developed an ultra-low nitrogen burner, which is characterized by safety, stability and low pollutant emissions. This product is applicable to several kinds of gas fuels (such as natural gas, urban gas, liquefied petroleum gas, etc.), meets the latest and most stringent national environmental protection standards, and can achieve the following technical indicators in long-term stable operation: ultra-low nitrogen oxide emission level (<30mg/Nm3), CO pollutant emission value<15ppm, SOx<3ppm, Noise<85db (A), etc. Combined with many years of technical engineering experience under complex chemical conditions, the combustion control concepts such as flue gas internal circulation, fuel grade, air grade, wall flow technology, etc. have been integrated. The low nitrogen control strategy of the whole unit has greatly improved the performance of ultra-low nitrogen oxide emissions and stable operation while maintaining a wide burner regulation ratio.
