A new burner, named PB-20 biomass pellet fuel burner, was developed at the Chinese Academy of Agricultural Engineering to solve the problem of easy flameout and slagging of burner during pellet combustion as there were higher ash and lower ash melting temperature in the pellet made of crop straw in China. The double combustion cylinder efficient device which adopted multi-level wind principles, a helix device breaking slagging and cleaning ash were designed. Combustion experiment with the corn straw pellet fuel and larch wood pellet was conducted after this pellet burner was made. The results showed the burner worked well and the ash and slagging were expelled because of double combustion cylinder efficient and helix device. The slagging rate is 23% and the combustion efficiency is up to 91%. The slagging rate of PB-20 biomass pellet fuel burner decreased by 25.94% and combustion efficiency increased by 9% compared with burner made from Sweden.
