Chemical equation for making water gas: C+H? O (g) = = (high temperature) CO+H? . CH？ +H？ O===CO+3H？ . Clean water gas (mainly COmposed of co and h? ), the phenomenon is that the flame rises higher and becomes light blue (the color of hydrogen and co combustion). The chemical equation is C+H? O (g) = = (high temperature) CO+H? .

Water gas:
Water gas is the gas produced by steam passing through hot coke. The main components are carbon monoxide and hydrogen, which release water and carbon dioxide after combustion, as well as trace carbon monoxide, hydrocarbons and nitrogen oxides. The combustion speed is 7.5 times that of gasoline, and the anti-explosion performance is good. According to foreign research and patent reports, the compression ratio can reach 12.5, the thermal efficiency can be increased by 20-40%, the power can be increased by 15%, and the fuel consumption can be reduced by 30%. The tail gas purification is close to Euro IV standard, and a small amount of platinum catalyst can also purify it.
Compared with alcohols and ethers, it simplifies manufacturing, reduces equipment, and has lower cost and investment. Compression or liquefaction is similar to hydrogen, but it doesn't need to remove CO, so the investment in building a station is low. The reduced cost and investment can also be used to partially compensate the investment and cost of compression (alcohol ether should also be compressed) or liquefaction. Toxic, used industrially as fuel and chemical raw materials.
Main components:
Air and steam are alternately introduced into the fixed bed coal gasifier to produce gas. Its components are roughly: CO25%, H250%, CO40%, N25%. The mixture of air and water vapor is continuously introduced into the gasifier for coal gasification reaction at high temperature. By adjusting the ratio of air to steam, the gasifier can run by itself, and the gas produced is called producer gas.
Its composition is roughly: CO25.5%, CO29%, H2 10.5%, N255%. Producer gas has high nitrogen content and is not suitable for synthetic ammonia feed gas, but it can be mixed with water gas, and can also be directly used as mixed gas of low calorific value fuel gas or city gas.
