Answer the landlord: At present, passing coal is generally used to make water gas, that is, the gas generated by steam passing through hot coke. The main components are carbon monoxide and hydrogen, and water and carbon dioxide are released after combustion, with trace amounts of CO, HC and NOX. The combustion speed is 7.5 times that of gasoline, and the explosion resistance is good. According to foreign research and patent reports, the compression ratio can reach 12.5. The thermal efficiency is increased by 2-4%, the power is increased by 15%, and the fuel consumption is reduced by 3%. The tail gas purification is close to the Euro IV standard (these indicators should be verified, but the effect is positive), and a small amount of platinum catalyst can also be used for purification. Compared with alcohol and ether, it simplifies manufacturing and reduces equipment, and the cost and investment are lower. Compression or liquefaction is similar to that of hydrogen, but there is no 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 as fuel in industry and as chemical raw material.
Clean water gas (mainly composed of CO and H2) can be produced by passing water vapor through a hot coal seam, and the phenomenon is that the flame rises higher and turns light blue (the burning color of hydrogen and CO). The chemical equation is C+H2O (high temperature)->; CO+H2。 This is why wet coal burns more vigorously than dry coal.
Gas plants often deliberately mix a small amount of odorous gas into household water gas, so that CO and H2 are colorless and odorless gases, which can be smelled and found in time when gas leaks.
