摘　　要：通过生物质气化低热值燃气在工业窑炉上燃烧的中试试验研究,得到不同燃烧条件下生物质燃气的窑炉燃烧温度特性。试验结果表明:常温空气助燃情况下,经低温净化的冷燃气的窑炉燃烧温度约1100℃,经高温净化的热燃气的窑炉燃烧温度约1200℃;如果回收燃烧烟气的余热,将助燃空气预热至400℃时,燃气窑炉燃烧温度可提高100~150℃。生物质气化低热值燃气基本能达到工业窑炉生产对温度的要求。The combustion temperature characteristics of biomass fuel gas under different combustion conditions in pilot industrial furnace were obtained through the combustion investigation of low heating value fuel gas from biomass gasification in a pilot industrial furnace. The experimental results show that using normal temperature air as combustion- supporting agent, the combustion temperature of cold fuel gas purifying in low temperature in industrial furnace is about 1100 ℃, and about 1200 ℃ for hot fuel gas purifying in high temperature; The raise of 100-150 ℃ of combustion temperature can be achieved when the air is preheated to about 400 ℃ through recycling the exhaust heat of combustion flue gas. Therefore, it is feasible to burn low heating value fuel gas from biomass gasification in industrial furnaces to meet the temperature requirements for industrial production.
