　　Definition and working principle4iWBoiler Burner

　　The burner designed according to the partial premixed combustion method is called the atmospheric burner.Its primary air coefficient is 0< 0< 1.The working principle of the atmospheric burner: the gas under a certain pressure, at a certain velocity from the nozzle, into the suction contraction tube, the gas by its own energy into the air.The gas and primary air are mixed in the ejector, and then flow out through the fire hole of the head for combustion, forming the Bunsen flame.4iWBoiler Burner

　　Part of the4iWBoiler Burner

　　The air burner is composed of head and ejector.4iWBoiler Burner

　　classification4iWBoiler Burner

　　The atmospheric burner usually USES gas to eject the primary air, so it belongs to the ejector burner.According to the different gas pressure, it can be divided into low pressure ejector type and high (medium) pressure ejector type.The former is mostly used for civil combustion, while the latter is mostly used for industrial installations.4iWBoiler Burner

　　Features and application scope4iWBoiler Burner

　　advantages4iWBoiler Burner

　　1. Shorter flame, stronger firepower and higher combustion temperature than the diffuser burner with natural draft.4iWBoiler Burner

　　2. It can burn gas of different properties, with complete combustion, high combustion efficiency and less CO content in the flue gas.4iWBoiler Burner

　　3. Low-pressure gas can be used. Since air is inhaled by gas, air supply equipment is not required.4iWBoiler Burner

　　4, strong adaptability, can meet the needs of more processes.4iWBoiler Burner

　　disadvantages4iWBoiler Burner

　　1. Because only part of the air is premixed, but not all the air required for combustion, the thermal strength and combustion temperature of the firehole are higher than that of the diffuser burner with natural induced air, but they are still limited and cannot meet some process requirements.4iWBoiler Burner

　　2. When the thermal load is large, the structure of the multi-hole burner is relatively bulky.4iWBoiler Burner

　　Range of application4iWBoiler Burner

　　Many fire hole air burner application is very extensive, in the family and public utilities in the gas appliances such as household stove, water heater, boiling water boiler and canteen stove with the most extensive, in the small boiler and industrial furnace also has the application.Single - hole air burners are widely used in small - and medium-sized boilers and some industrial furnaces.4iWBoiler Burner
