户用生物质气化炉焦油净化技术研究

Tar Purification Technology in Household Biomass Gasifier

比较了生物质集中供气技术与户用生物质气化技术。通过炉型分析,提出了上吸式生物质气化炉是农村户用气化炉型的理想选择;同时,分析了目前户用生物质气化炉存在的问题,认为催化裂解是户用气化炉焦油净化的有效途径。在分析小型气化炉焦油净化技术的基础上,开发了一种设置二次催化裂解与分离回收装置的新型气化炉。该炉能利用燃气显热,有效回收液态焦油和冷凝水,具有焦油裂解转化效果好、气化炉效率和燃气热值提高等优点。

Comparison of biomass centralized gas supply and household gasification technology.By the characteristic analysis of furnace type,downdraft gasifier is in the rural the use of the ideal type of furnace.Analysis of problems in the currently used household gasification furnace.That is tar effective purification method for catalytic cracking of tar.Based on the analysis of the existing small gasification furnace purification method,puts forward a two catalytic cracking and separation device of the gasification furnace.It can use gas sensible heat,recovery of liquid tar and condensed water.It has advantages of high tar cracking efficiency,the gasification efficiency and high heat value of fuel gas.
