The invention provides an environmentally-friendly and energy-saving
alcohol-based fuel additive. The
alcohol-based fuel additive is prepared from the following components according to the weight of every 10 kilograms of
alcohol-based fuel additive: 1-3 kg of a
flame continuing agent, 2-7 kg of a heat value
enhancer, 1-3 kg of a cosolvent, 0.1-0.5 kg of an
antioxidant, 0.1-0.5 kg of a detergent and 10-50 g of a
preservative. The alcohol-based fuel additive is an additive specially used in the gasification and
combustion processes of alcohol-based fuel, so that the problem of
carbon deposit generated in the gasification process of the alcohol-based fuel can be thoroughly solved, gasification becomes very easy, complete gasification and full
combustion are realized, the
waste gas emission standard is lower than the national relevant standards by 10 times or more, the alcohol-based fuel additive is really clean,
environmentally friendly and energy-saving, meanwhile the problem of low heatvalue of the alcohol-based fuel can be thoroughly solved, the firepower can be very strong in the
combustion process of the alcohol-based fuel, the
flame temperature reaches 1300 DEG C, energy can besaved by about 35% compared with that of liquefied gas, and remarkable
economic benefits are achieved; and the popularization of a gasification and combustion mode of the alcohol-based fuel is changed from ideality to reality.
