NOVELTY - Realizing stable combustion of alcohol base fuel involves taking diethyl methoxyl borane solution as a reactive additive. Nano-additive is added in a base fuel. The base fuel is uniformly mixed under room temperature environment by physical method. A self-propagating oxidation exothermic and nano-particle vaporization center of heat transfer enhancement effect is generated by using the reactive additive in-situ free radical to reduce thermal resistance effect of a gaseous insulating layer. Evaporation rate of an alcohol fuel is increased to realize inhibition of negative temperature coefficient effect in combustion process. USE - Method for realizing stable combustion of alcohol base fuel at wide temperature range based on inhibiting negative temperature coefficient effect. ADVANTAGE - The method has short ignition delay time, strong middle-low temperature self-flammability, stable combustion, and good normal temperature storage stability. The operation is simple and easy and strong practicability.
