摘要
与直燃相比,生物质气化技术减小了收集半径,降低了收集运输难度,且回避了对锅炉受热面沾污和燃烧产物回收利用的影响,具有显著的技术优势。但由于新增了生物质气化装置,系统更为复杂且提升了发电成本;生物质气化过程产生的焦油,尚缺乏可靠的脱除技术,限制了该技术的规模化应用。列举了国内外气化发电工程实例及直燃发电工程实例,对比并简述了我国生物质气化发电现状,分析了其发展前景及障碍。
Comparing with direct firing, biomass gasification technology has small collection distance, reducing collecting and transportation difficulty, and avoid fouling on boiler heating surface, as well as advantages in recovery of combustion products. But as the adding of biomass gasifier, the system is more complicated and increase the power generating cost. Examples of abroad and domestic biomass gasification project are taken, and compared with Chinese situation. The prospect and obstacle of biomass gasification and power generation is analyzed.
