Abstract

Abstract The insufficient amount of the earth’s fossil energy urges the development of Green Energy. Among them, the wood pellet, which are processed by useless woods, own very high economic efficiency and combustion efficiency during their combustion. According to existing burner, aiming to figure out the problems of the calorific value and low combustion efficiency, the difficulty of dealing with burning ash powder. The institute has developed cyclonic wood pellet burner. In order to find out what’s special about the cyclone particles and its fuel efficiency, this paper would utilize wood pellet as material, using 3D feeding system and gas analyzing system to do theresearch. Through the investigation of the pellet burner combustion conditions, we sought out the best way of ignition and the best condition of it. Through the analysis of exhaust gas under different conditions after burning, we were able to conclude that the best conditions of combustion and burning effect. When first air supply is fixed at 2L/min, the fuel material into the combustor of 15g, second air supply at 210L/min air condition, the combustion effect is best; When first air supply at 2L/min is fixed, the fuel into the combustor of 30g, second air supply at 490L/min air condition, the combustion effect is best. And there is few toxic gas such as CO and HC among the exhaust gas. After numerous experiments, we are able to prove that the cyclonic wood particles burner can make the combustion more efficiently and deal with the burning dust with higher efficiency, according to the first and second air change of gas supply.
