摘要/Abstract

摘要：

为了明晰富氧燃烧、生物质/煤混燃共同作用下NO释放规律，利用自制等温热重及污染物同步测量系统，在富氧气氛下对生物质/煤混燃过程中NO的释放规律进行了研究，探讨了气氛、温度、生物质掺混比、煤种和生物质种类对NO释放的影响规律。结果表明：O2浓度为21%时，阳泉煤掺混20%玉米芯样品在富氧气氛下NO双峰和转化率均小于空气气氛；随氧浓度升高，NO释放速率曲线由双峰变为单峰，样品NO转化率增大；随玉米芯掺混比增加，NO转化率呈下降趋势；随温度升高，样品NO转化率增大；煤掺混玉米芯后，NO转化率均有降低，阳泉煤在掺混生物质后NO转化率均有下降。

Abstract:

To clear the NO release law under the interaction of oxygen-enriched combustion and biomass/coal co-combustion， this paper studied the NO release characteristics during biomass/coal co-combustion process in oxygen-enriched atmosphere， and discussed the influence law of atmosphere， temperature， biomass blending ratio， coal type and biomass type on NO release characteristics， with using homemade iso-thermal TGA and pollutants synchronous measurement system. The results show that two peaks and conversion of NO in oxygen-enriched atmosphere are less than that in air atmosphere when Yangquan coal blending 20% corn cob at 21% oxygen concentration. As oxygen concentration increasing， the NO release rate curve is changed from two peaks to one peak， and the NO conversion of samples increases. As the biomass blending ratio increasing， the NO conversion shows a decreasing tendency. The NO conversion of samples increases with the temperature rising. The NO conversion decreases when coal blending corn cob；and the NO conversion decreases when Yangquan coal blending biomass.

Key words: oxygen-enriched atmosphere, co-combustion of biomass and coal, co-combustion at constant temperature, NO release characteristics
