Design, Experimentation And Simulation Of The Upward Ventilating Biomass-gasification Stove

Energy is the most important problem in the world. Biomass resource is an efficient substitute for energy and can mitigate the scarcity of energy. Moreover, biomass resource in our country is rather abundance, we should strengthen the research that can make use of biomass resource.(1) small upward ventilating biomass-gasification stove was been designed. The stove can satisfy the request of gasification for various familiar biomass, and the reaction temperature of different react zone can be measured to research the influence of reaction temperature on gasifies reaction.(2) This paper studies the relationship between the in-stove temperature and blasting air for upward ventilating biomass -gasification stove. The results of the experimentation indicate that at the situation of small blasting air amount, the in-stove temperature increases notably with the increase of blasting air quantity, but the increase of the in-stove temperature begins to slow when the blasting air reaches a certain amount.( 3) The CHEMKIN software is used to simulate the upward ventilating biomass-gasification stove. The factor that influents the reaction of the pyrolysis zone is material surface temperature but not environment temperature. The surface temperature is decided by environment temperature and heat transfer rate .The environment temperature of gasifies reaction is in certain scope, so enlarging heat transfer rate is advantageous to pyrolysis reaction. The reactions of oxidize zone and reoxidize zone carry on quickly, so when the environment temperature and surface temperature are in the given scope, they make little influence to the reactions of the two zones. The major reaction of reoxidize zone is water gas reaction.
