摘要

煤燃烧是大气中PM2.5的主要来源之一

控制燃煤过程中PM2.5的排放有助于改善空气质量。燃煤过程产生的PM2.5主要由超细模态颗粒物及中间模态颗粒物构成

其形成机理各有不同

炉内控制是一种有效抑制PM2.5生成的手段。对几种主要的炉内PM2.5控制方式

包括优化煤质及燃烧条件、炉内喷入高岭土或石灰石等添加剂以及混煤或煤与生物质、污泥混燃等的研究进展进行了综述

提出了控制PM2.5生成应综合考虑对炉内结渣粘污的影响

并尽可能实现PM2.5与痕量元素等多种污染物的联合脱除。

Abstract

Coal combustion for power generation is one of the main sources of PM2.5in the atmosphere.PM2.5reduction during coal combustion contributes significantly to improving atmospheric environmental quality in the city.PM2.5generated from coal combustion mainly consists of two types of particulate matter

namely the ultrafine mode particles and central mode particles

which are formed in different mechanisms.Control in furnace is an effective strategy for PM2.5reduction during coal combustion

including optimization of coal properties and combustion conditions

additive injection like kaolin and limestone

coal blending and co-combustion with biomass and sewage sludge.In addition

slagging and fouling should be considered because of changes in mineral transformation.It is economical to achieve multi-pollutant removal during PM2.5reduction.
