How is the gas generated from gas, water gas, and coke oven gas burners?
Gas burners are commonly referred to as low calorific value burners and are used in industrial equipment such as boilers, steelmaking furnaces, glass furnaces, and dryers. Common gas types include producer gas, water gas, and coke oven gas. Do you know how these burner gases are generated? Let the editor of Europa explain to you:
Gas producer: Solid fuel is converted from gas producer to gaseous fuel. There are many types of gas, including coke oven gas, producer gas, water gas, oil gas, blast furnace gas, cracking gas, etc. The production method of producer gas is to burn coal in the producer furnace, limit the air at the bottom of the furnace, and prevent complete combustion of coal, resulting in the production of a large amount of carbon monoxide, namely producer gas. This method causes the main gases discharged from the furnace to be carbon monoxide, carbon dioxide, and nitrogen.
The production method of water gas is to ignite the coal in the furnace, blow enough air into the furnace bottom to make the coal burn fiercely, then stop the fan, inject steam from the furnace bottom and top, and combine with hot gas. Coal produces a large amount of hydrogen and carbon monoxide, which are then mixed with nitrogen in the air and remaining water vapor to form water vapor.
The production method of coke oven gas burner is to crush the raw coal, wash it clean, and mix it into the coke oven according to the proportion of different coal types, isolate the air and heat it. High temperature decomposes coal to produce gas and coal tar. Using coal or coke as raw material and air and steam as gasification agents, the gas is introduced into the gas produced by the gas furnace. It is the most commonly used gasification gas, produced using the moving bed gasification method. The production factory is called a gas power plant. The gasification process of the generator: Put the gasification raw materials into the furnace from the top. The entire fuel layer is supported by a grate. The gasification agent enters from the bottom of the grate, is evenly distributed through the grate, and undergoes gasification reaction in contact with the fuel layer. The generated gas is extracted from above the fuel layer. The remaining ash is discharged from the bottom of the grate. This gas-solid two-phase countercurrent operating furnace can fully utilize the heat of the ash to preheat the gasification agent, and also fully utilize the sensible heat of the gas rising from the gasification layer to heat the fuel, dry and pyrolysis, thereby improving the thermal efficiency of the furnace; And the volatile matter in the fuel does not undergo high-temperature cracking, thereby increasing the calorific value of the gas. The extracted gas contains CO, H2, CO2, N2, CH4, C2H4, H2S, H2O, nitride, and tar vapor.
