Abstract:
The thermogravimetric analyzer and horizontal tube furnace are used to study the effects of operation parameters such as temperature, fuel type, and oxygen concentration on the combustion and NO emission characteristics of the rice husk, rice straw, and peanut shell in the O2/CO2 atmosphere. The results show that the combustion performances of volatile matter and fixed carbon of the three biomasses increase with the increase in the O2 content. The mean NO emission increases sharply when the reaction temperature increases from 700 to 800 ℃. However, it increases slightly when the temperature exceeds 800 ℃. Meanwhile, the mean NO emission and nitrogen conversion decrease with the increase in the nitrogen content in biomass. The mean NO emission changes little with different oxygen concentrations, and the NO emissions of the three biomasses are all lower than the requirement for the minimum NO emission. Increasing the oxygen concentration favors the biomass combustion in the O2/CO2 atmosphere, and oxygen concentration has little effect on the NO emission.
采用热重分析仪、管式炉试验研究了反应温度、燃料种类、氧浓度等操作参数对稻壳、稻杆、花生壳3种生物质在O2/CO2气氛下的燃烧特性和NO排放特性.试验结果表明:随着O2含量的增大, 3种生物质的挥发分和固定碳的燃烧性能均随之增加;当反应温度由700 ℃增加到800 ℃时, NO的平均排放量随温度升高迅速增加, 当反应温度高于800 ℃, NO平均排放量增幅趋于平缓;NO平均排放量和氮转换率随着燃料中N含量的增加而减少;NO平均排放量随氧气浓度变化较小, 低于NO排放标准.增加O2浓度有助于促进生物质在O2/CO2气氛中的燃烧, 同时对NO生成的影响较小.
