摘要

我国W火焰锅炉以B公司和D公司的产品为主

对B公司600MW等级和D公司660MW等级W火焰锅炉的技术特点进行了比较

其中B公司在燃烧器及锅炉分级配风设计方面与其300MW等级锅炉基本接近

未采取更为有效的技术手段

在NOx排放方面有较大的技术改进空间;D公司在该等级锅炉的分级配风设计中

取消了300MW等级W火焰锅炉的E挡板、增加了拱上燃尽风

极大地改善了W火焰锅炉的NOx排放问题。

Abstract

China's W flame boilers are most manufactured in company B and D.Comparison of technical features between the supercritical 600MW unit W flame boiler produced from company B and the supercritical 660MW unit W flame boiler produced from company D were conducted. For company B

the burner and staged air distribution design for 600 MW units was closely the same as that for the 300MW unit

and no more efficient technical means was under taken

moreover

there is still large space for technical improvement in NOx reduction.For company D

there's large modification on staged air distribution design for 300MW level units

such as cancelling the E damper for 300MW units and increasing the over fire air on the furnace arch

greatly decreasing the NOx emission.
