Atmospheric pollution and industrial discharge are common difficult problems that are urgent to be solved currently for all the countries in the world. At present, the industrial fuels used on international are still the diesel oil, natural gas, coal, liquefied gas and electricity which have high cost or high pollution. How to realize mutual benefit and double-win in environmentally-friendly social benefit and enterprise economic benefit has bothered the industrial circle and each government for a long term. And the market starves for a novel environmentally-friendly industrial fuel which is highly efficient, can greatly save energies, has cheap and widely available raw materials for production, and is suitable for large scale production. On the current market, the popular alcohol-based fuels are various in categories and differentiated in qualities, all have low heat values, unstable performances and narrow application scopes, and cannot be safely produced, stored and transported in large scale, therefore can only suitable for civil use but cannot satisfy the various complicated operation requirements in the industrial field. On the other hand, the waste liquid of a sugar mill generates a great deal of pollution, and requires a great amount of manpower and financial resources during treatment. If the waste liquid of the sugar mill can be burned directly as a fuel, then not only a great deal of waste liquid can be treated, but a great amount of heat energies will also be generated.
