摘要

有机固体废弃物（OSW）中含有多种重金属，燃烧过程会随烟气排放，造成一定的环境危害，因此对OSW和褐煤掺混燃烧过程灰分中的重金属迁移和颗粒物生成特性进行了实验研究。结果表明：燃料在燃烧过程中各种重金属的释放不单取决于燃料本身的质量浓度，而且和高温作用下的化学机制密切相关；混合燃料烟气中产生Pb、Cd、As元素的含量明显低于典型燃料和校核燃料单独燃烧时烟气中产生的重金属元素含量；而Cu、Zn、Co、Mn在飞灰中均有较高质量分数；800、850℃下选用的4种燃料制得的灰分的粒径分布均大致呈现单峰正态分布；当温度升高到900℃后，除产生小粒径灰分外，还可能会产生较大粒径的灰分颗粒。

Abstract

Rapidly growth of organic solid waste(OSW) has caused serious social and environmental issues. Cocombustion is an economical and environmental method to treat OSW. However

there will be a variety of heavy metals discharged with flue gas during combustion as OSW contains them. Therefore

this study conducted an experiment on the migration of heavy metals and generation of micro particles during the co-combustion of OSW and lignite. The results show that

the release of heavy metals during combustion not only depends on the concentration of heavy metal the fuel contains

but also on the chemical mechanism at high temperature. The content of Pb

Cd and As in the flue gas of blending fuel is obviously lower than that of sole OSW

but Cu

Co and Mn shows opposite tendency. In addition

the particle size distribution of the four fuels all shows a normal distribution at 800 ℃ and 850 ℃

but large particle size generates when the combustion temperature rises to 900 ℃.
