The invention discloses a solid alcohol fuel, which is prepared in two steps at a constant temperature of 70°C by weight percentage from 90.73% industrial alcohol, 4.76% stearic acid, 0.62% NaOH, 1.30% paraffin, and 2.59% distilled water. to make. The solid alcohol fuel of the present invention has the characteristics of easy ignition, high combustion calorific value, no black smoke, no peculiar smell, less residue after combustion, long storage period, no softening and separation, etc., especially under the condition of vacuum anoxic, it can still maintain The combustion is stable, the flame is strong, and it has good combustion performance. It can still burn in the plateau or mountain environment at an altitude of more than 6300 meters. Compared with ordinary solid fuels, the solid alcohol fuel of the present invention has a wider application range, and has obvious advantages in plateau anoxic areas, and is the preferred heat source for home furnishing, travel, sports, or field training for soldiers in plateau areas, as well as plateau and mountain combat.
