Briefly describe the low nitrogen burner of the thermal oil furnace
The thermal oil furnace, also known as the organic heat carrier furnace, is commonly known as the thermal oil boiler, officially known as the thermal oil furnace. It is a new type of thermal energy equipment that uses coal, oil, and gas as fuel and thermal oil as the circulating medium for heating. A thermal oil furnace refers to a new type of thermal energy conversion equipment that uses high-temperature thermal oil (also known as thermal coal or heat carrier) as the heat carrier. The advantages of a thermal oil furnace are high temperature and low pressure, stable operation, and widespread use.
The emissions from domestic environmentally friendly ultra-low nitrogen thermal oil furnace burners are less than 30mg/L. Methanol and natural gas are used as fuels to provide efficient heat energy for thermal oil boilers. In addition, the ultra-low nitrogen burner adopts a unique structural design, which causes the flue gas generated during the combustion process to form a forced reflux near the furnace, stabilize the flame, reduce oxygen concentration, and reduce NOx emissions. At present, low nitrogen burners are mainly used for the renovation of various petroleum refining heating furnaces, large steam boilers, and coal-fired boilers. Thermal oil, also known as organic heat carrier or heat medium oil, has a history of over 50 years in industrial heat exchange processes. The burner of a thermal oil furnace generally uses coal, oil, and gas as fuel, thermal oil as medium, and a hot oil circulation pump to force the medium to undergo liquid-phase circulation. The heat energy is returned to the heating furnace for heating, and high working temperature is obtained under low pressure, which can accurately control the operation of the medium. Most burners of gas thermal oil boilers are imported, and the introduced low nitrogen burners burn well and are environmentally friendly products. When the outlet oil temperature of the ultra-low nitrogen burner boiler 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. When the outlet oil temperature of the boiler is higher than the set outlet oil temperature limit by -5 ℃, turn off the two stages of the burner. When the outlet oil temperature of the first stage of the boiler is higher than the set outlet oil temperature limit, turn off the inlet burner alarm of the first and two stages of the burner, and immediately turn off the boiler burner. The main supply of natural gas is natural gas. The main functions of a refrigerator are the refrigerator and the control room. The function of the burner is to check ignition, adjust the ratio of fuel and air, and control the opening of the burner according to the load. An air preheater is a device that uses exhaust gas to heat the flue gas.
The environmental protection standard for low nitrogen burners in thermal oil industrial boilers requires that the boiler's emissions be less than 30 milligrams, overcoming the offensive of atmospheric management, promoting technological progress in energy utilization industry and sustainable social development, and improving the quality of ecological environment. The domestically produced ultra-low nitrogen burner, Europa, is highly welcomed by many domestic enterprises. We have developed a low nitrogen burner with stable operating performance, complete safety logic, low pollutant emissions, 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 around a professional combustion program control system, meeting the needs of user equipment for highly integrated, automated, and low maintenance of the burner system. Small and medium-sized thermal energy equipment generally includes small and medium-sized industrial boilers, such as hot water boilers below 8 megawatts, steam boilers, thermal oil heating furnaces, and other heating medium equipment; It also includes general production heating technologies such as food thermal processing, hot air stoves, and baking equipment. Some process equipment such as incinerators and paint exhaust gas treatment. Domestic brand - Europa has developed an ultra-low nitrogen burner, which is characterized by safety, stability, and low pollutant emissions. This product is suitable for several types of gas fuels (such as natural gas, urban gas, liquefied petroleum gas, etc.), meets the latest and strictest national environmental standards, and can operate stably for a long time to achieve the following technical indicators: ultra-low nitrogen oxide emission level (<30mg/Nm3), CO pollutant emission value<15ppm, SOx<3ppm, Noise<85dB (A), etc. Based on years of technical engineering experience in complex chemical working conditions, combustion control concepts such as flue gas internal circulation, fuel level, air level, and wall flow technology have been integrated. The low nitrogen control strategy of the entire unit greatly improves the performance of ultra-low nitrogen oxide emissions and stable operation while maintaining a wide burner regulation ratio.
