摘要

在广西某电厂W型火焰锅炉进行越南无烟煤与山西大友烟煤掺烧试验

掺烧方式采用炉前掺烧和分仓掺烧

掺烧时采用烟煤比例逐步递增方式。通过比较不同掺烧方式和掺烧比例下炉膛结焦情况、灰渣可燃物含量、火焰温度水平以及制粉系统安全性的变化趋势

确定越南无烟煤与山西大友烟煤最大掺烧比例为4∶6

推荐采用炉前掺烧方式

Abstract

Experiment on co-firing of Vietnamese anthracite and Shanxi bituminous coal in a W-flame boiler was conducted

by pre-mix and late-mix ways.During combustion

the proportion of bituminous coal was gradually increased.The variation trends of slagging situation

combustible ash content

flame temperature and pulverizing system safety with different co-firing ways and mixed ratios were compared.The results showed that

the best anthracite/bituminous mass ratio was 4:6

and the pre-mix way was suggested.
