摘要
生物质能是可再生能源,生物质燃料具有CO2净排放为零的特性,对它的利用可减少温室气体排放,符合实现可持续发展的要求。生物质燃料再燃方式包括直接再燃、间接再燃和高级再燃等3种方式,都能有效减少NOx排放。利用木柴直接再燃的研究较多,采用人工模拟生物质气化气是研究间接再燃的有效途径。生物质燃料种类、尺寸、组分,燃料携带气,燃料喷入位置、燃尽风、再燃区过量空气系数等多种因素影响再燃。对我国开展生物质燃料再燃研究提出了建议。
The biomass is a kind of regenerative energy source and biomass fuel features a zero amount of net CO_2 emissions.The use of biomass fuel can reduce greenhouse gas emissions,meeting the requirements for realizing sustainable development.The modes of biomass fuel reburning include: direct reburning,indirect and advanced reburning.The above three modes can without exception effectively reduce the NO_x emissions.A relatively large amount of research involves the use of wood for direct burning and the use of the gasified gas of artificially simulated biomass represents an effective means for the study of indirect reburning.A variety of factors can influence reburning.They include: biomass fuel types,its size,constituent elements,fuel-bearing gas,fuel injection location,burn-off air and excess air factor in the reburning zone.Finally,some proposals for furthering the study of biomass fuel reburning have been put forward.
