Bio-alcohol oil is a safe, environmentally friendly, energy-saving and fuel. It can be used in a series of products, such as hotels' big stoves, small and medium-sized restaurants' fierce stoves, household gasifiers, hot pot stoves, etc. In addition, it can adapt to small restaurants burning coal and families widely using honeycomb coal, with strong firepower, remarkable energy-saving effect, no need for fans and convenient use. It can not only replace liquefied petroleum gas for thousands of households, but also replace diesel oil for canteens in hotels, restaurants, food stalls, schools, factories and other enterprises and institutions, and can also be used for other industrial purposes, such as some industrial furnaces or boilers. Bio-alcohol oil is actually a common name of alcohol-based liquid fuel, and most people call it bio-alcohol oil. The national standard is GB16663-1996 alcohol-based liquid fuel. Bio-alcohol oil is a kind of highly clean biomass liquid fuel which is synthesized by chemical blending with methanol (such as methanol, ethanol, butanol, etc.) as the main raw material according to a specific technological formula. It exists in liquid or solid form. It is also a kind of biomass energy, which, like nuclear energy, solar energy, wind energy and hydraulic energy, is an environmentally-friendly and clean energy that governments all over the world are vigorously promoting at present. Facing the exhaustion of petrochemical energy, bio-alcohol oil is the most potential new alternative energy, which is favored by enterprises and organizations in various countries. After more than ten years of experiments and practice, bio-alcohol oil has been proved to be completely acceptable in the market and well received by the majority of users. Bio-alcohol oil has the advantages of full combustion, no black smoke, no carbon deposit, no black pot bottom and no residual liquid residue, good environmental protection characteristics, good stability and no corrosiveness, and can be stored, transported and used at normal temperature and pressure. Bio-alcohol oil has the advantages of environmental protection, energy saving, fierce firepower, non-toxicity and smokeless, and is widely used in hotels, restaurants, institutions, military units, schools and catering industry. It is an alternative fuel for hotels, restaurants, institutions, military units, schools and catering industry.
