Abstract

The invention relates to a clean type solid fuel which is burnt in low temperature and low pressure. The fuel comprises the components of hydroxyl-terminated polybutadiene, ammonium perchlorate, ammonium nitrate, toluene diisocynate, nitro cotton, plasticizer, equalizer and potassic nitrate, and odor regulator and / or flame color regulator can also be added. The fuel has the advantages of strong combustion blaze, good blaze visibility, less burnt residue, clean burning, high burning heat value, smokelessness, innocuity, high wind resistance and high security; the fuel can be continuously and stably burnt particularly under the environmental condition of 0.02 MPa and minus 40 DEG C, and can not be put out in strong wind, heavy rain and heavy snow when being matched with a special burner; the solid fuel with good and reliable performance is provided for delivering a torch at the peaks of summits (including the Everest), and can be limitlessly used on the terrene; the fuel is particularly suitable for the field operation in extremely cold areas, and the portable and reliable solid fuel with high heat value is provided for wild lives, wild mountaineering, expeditions, heating, field training and signal setting off.

Description

technical field [0001] The invention belongs to the technical field of solid fuel, and mainly relates to a solid fuel formula and preparation method for stable and clean combustion under low-pressure and low-temperature conditions. Background technique [0002] The use of solid fuel has a history of many years. People often use this fuel in their daily life. It has the advantages of being portable and suitable for field use. At present, the commonly used solid fuels mainly include solid alcohol type, urotropine type, coal type, plant powder type and cellulose type. Due to the low oxygen content in their own composition system, the use of combustion is limited. , generally have the disadvantages of relatively low calorific value, poor wind resistance, and narrow use environment, and are only suitable for indoor use in low-altitude (below 3000m) areas or outdoor environments where the wind force does not exceed level 7. Especially the current solid fuel is not suitable for us...
