Prescription Of Honeycomb-Shaped Biomass Fuel And The Matched Equipment Design

According to estimate, the containing coal and oil that can be exploited in the world will be exhausted in 200 years and 30-40 years respectively, moreover, natural gas can only be used 60 years at the ratio of store-pick, therefore, the short of energy will be one of important factors that impedes the development of human society, so it is imperative to discover and exploit new energy. Biomass energy is the main energy used by mankind before the late of 17th century, even today, the utilization of biomass energy still accounts for 14 percent in the world energy consumption, to be equal to 20.82 hundred million tons coal equivalent, however, the ratio in developing countries is bigger, it accounts for 35 percent in total energy consumptions, to be equal to 16.97 hundred million tons coal equivalent. That is to say, there is about 25 hundred million people using biomass energy for cooking, warming and lighting, but the quantity is less than 1 percent in general annual production. In conclusion, the prospects of using biomass energy are very widely.There is about 4. 3 hundred million tons biomass straw fired in our country every year. Biomass such as straw, sawdust etcis burned directly resulting in air pollution as well as waste of energy, however, with the development of society and economy as well as the progress of people' s consciousness about environmental protection, the rich has not fired firewood for cooking and warming, as a result, much straw is discarded here and there. This not only wastes energy but also hides much danger, therefore, it is imperative for us to find a practicable solution to solve this problem.This discourse comprises prescription of honeycomb-shaped biomass fuel and the designing of the matched equipment. We develop a set of practicable prescription which is composed of eliminating smoke combustion-supporting regent and felt regent as well as chemical oxidant by the analysis of combustion mechanism. We design a set of machine whose productivity is 16 pieces of pellets per minute in terms of biomass specific property. This equipment is composed of providing stuff setting, condensation molding fitting and transport product set, and so on. It compresses loose biomass materials to closer ones which not only improve its combustion characteristic but also make it convenient to carry, as a result, it will benefit to environmental protection and sustainable economy development. In a word, this achievement is worthy to be popularized in our country.
