Blind fire tinder fuel in condition of low temperature and low pressure

Abstract

The invention provides a fire source fuel for the combustion of low-pressure and low-temperature blind fire. The invention comprises following components in percentage by weight percent: 75 to 85 percent of powdered charcoal, 6 to 10 percent of potassium nitrate, 5 to 10 percent of potassium perchlorate, 1 to 5 percent of binding agent, 0 to 2 percent of ammonium nitrate and 0 to 1 percent of burning-smell regulator. The manufacturing process of the fire source fuel is environment friendly and high in safety. Results of on-the-spot tests show that the fire source fuel of the invention can burn in blind fire under conditions of the elevation of 8800m and the temperature of 45 DEG C below zero and can continue to burn for quite a long time, the ignition quality is reliable and stable, the flame can not be extinguished under weathers of gale, rain and snow, the combustion of the fire source fuel is of safety, reliability, no smoke and no toxicity, and the fire source fuel is convenient in carrying and can meet requirements of people who need to carry fire sources while climbing peaks, thereby the invention provides the solid fire source fuel which is convenient in carrying and capable of burning in blind fire for quite a long time for field mountaineering, expedition and field operation training; the invention is wide in use conditions and environments and can be used in all places of the earth, particular in alpine regions for outdoor use (the elevation is more than 3000m and the ambient temperature is less than 0 DEG C), and the invention can be used to the conservation of the fire source for warm-getting, field mountaineering and expedition.

Description

Low-pressure low-temperature dark fire burning kindling fuel technical field The invention belongs to the technical field of solid fuels, and mainly relates to the formulation and preparation method of a tinder fuel for continuous and stable dark fire combustion under low-pressure and low-temperature conditions. Background technique Dark fire burning kindling fuel is a kind of solid fuel, which is often used in daily life for long-term heating and for long-term preservation of kindling in an environment where fire is inconvenient; it has the characteristics of portability, long burning time, and is suitable for outdoor use. Advantages of using. At present, there are mainly coal type and plant powder type as the kindling fuel for dark fire combustion. Because they generally have the disadvantage of low oxygen content in their composition, which limits the combustion characteristics, they are only suitable for low-altitude areas (below 3000m) It can be used indoors or in a ...
