摘要

生物质直燃发电的规模化使生物质燃烧过程中产生的污染物问题受到越来越多的重视。硫氧化物和氮氧化物作为两种主要的大气污染物

严重危害自然环境。结合生物质中硫赋存形式

对温度、灰成分等条件对生物质燃烧过程中硫迁徙的影响以及生物质的自身固硫特性进行了研究。对于氮氧化物的生成

研究主要集中在热解过程氮氧化物前驱物(NH3、HCN、HNCO等)的生成上。结合生物质氮赋存形式

对温度、燃料种类、升温速率等条件对氮氧化物前驱物生成的影响

以及对挥发分燃烧过程中氮氧化物的生成机理进行了综述。

Abstract

The problem of pollutant emission in the process of developing large-scale power generation by burning directly the biomass have drawn more and more attention.The sulphide and nitrogen oxides are two kinds of main atomospheric pollutants

seriously threatening the natural environment.Combined with the existed form of sulphur in the biomass

the influence of conditions

such as temperature and ash composition etc.

upon sulphur migration in burning process of biomass

as well as sulphur-solidifying behavior in the biomass proper

have been far more discussed in the studies already made.With regard of formation for nitrogen oxides

the studies are mainly concentrated on the formation of prodromal matters (i.e.NH3

HCN

and HNCO etc.) for nitrogen oxides in the process of pyrolysis.For this

combined with existing form of nitrogen in the biomass

the influence of conditions

such as temperature

fuel sort

and temperature rise rate etc.upon teh formation of prodromal matters for nitrogen oxides

as well as the formation mechanisms of nitrogen oxides in the process of burning volatile matters have been summarized up.
