In the face of exhaustion of fossil energy, alternative energy sources to fossil energy are actively sought. Many boiler research institutions at home and abroad aim at clean and cheap alternative fuels such as natural gas, methanol, electricity and the like. Alcohol-based fuel is the most potential novel alternative energy source, and is fuel prepared by taking alcohols (such as methanol, ethanol, butanol and the like) as main substances. It is in liquid or solid form. The solar energy is also biomass energy, is the same as nuclear energy, solar energy, wind energy and hydraulic energy, and is an environment-friendly clean energy widely popularized by the governments of various countries at present; is deeply favored by enterprises of various countries. The molecular formula of the methanol is single compared with that of coal, gasoline and diesel oil, the combustion emission is very clean, and no particulate matters (PM 2.5 and PM 10), ozone, sulfur dioxide, CO, mercury and compounds thereof are contained, and the emission of nitrogen oxides is more than 10 times lower than that of a natural gas boiler. The methanol fuel can replace coal and diesel oil and can greatly relieve the pollution to the atmosphere in China.
