在蒸汽锅炉进行生物质能源改造中,生物质气化燃气代替煤、油具有成本、环保、政策方面的优势,但必须解决焦油的二次污染问题。本文提出以改进型即中部出气固定床上吸式气化炉生产生物质可燃气,及焦油成分随燃气直接在锅炉炉膛燃烧的技术路线,并以2T/h蒸汽锅炉为例对气化炉的主要结构参数进行设计计算。采用基于锅炉输出蒸汽压力的气化炉鼓风自适应控制方法实现系统的闭环控制。最后通过实际应用案例实测数据的热能计算证明生物质气化燃气在蒸汽锅炉中代替煤、油燃烧的可行性。

For biomass energy transformation in steam boilers, gasification gas has more advantages than coal or oil, such as cost, environmental protection, and policy benefits. However, we must solve the problem of secondary pollution out of tar in its application. In this paper, firstly we propose an improved technical solution, which can produce high heat value, low tar content biomass gas by updraft fixed-bed biomass gasifier with gas outlet in the middle position, and the tar composition burned directly in boiler furnace with biomass gas. Based on the technical solution, we take 2 T/h steam boiler for example to design and calculate the main structure parameters of the gasifier. Next, we provide an intelligent adaptive control on air supply of gasifier according to steam pressure. Finally, the feasibility and efficiency of biomass gas as a new boiler fuel was proved through the test data in practical application cases.
