Straw gasifying furnace

The utility model relates to a biological gasifying furnace, particularly a straw gasifying furnace. The defects of incomplete extinguishment or combustion, resource waste and environment pollution are caused easily because the seal between a combustor and a gasifying barrel of the existing straw gasifying furnace is not tight, and the airflow between the combustor and the gasifying barrel is not stable. Thus, the utility model has the structure that an upper sealing steel ring and a lower sealing steel ring, the slope angles of which are consistent with each other are utilized to seal between a combustor and a gasifying barrel, so the effects of continuous and stable flame and no extinguishment are realized, and the problem that fuels containing 30%-35% moisture can not be cracked to generate gas to be combusted is overcome. The utility model has the advantages of simple structure, easy operation, resource saving and environment protection. 本实用新型涉及一种生物质气化炉，尤其涉及一种秸秆气化炉。针对现有秸秆气化炉燃烧器与气化桶之间由于密封不严密，气流不稳定，易导致熄火或燃烧不完全，浪费资源及污染环境的缺点。本实用新型燃烧器与气化桶之间用带倾斜角度相吻合的上密封钢环与下密封钢环密封，来达到火焰持续稳定、不熄火，解决了水分30％～35％的燃料不能正常裂解产气燃烧的问题，结构简单、操作简便、节约资源及保护环境。
