摘要

对同心切圆燃烧系统(CFS)中偏转二次风对炉内动力场、结焦、NOx排放等的影响进行了研究和探讨

分析了偏转二次风设计中应注意的问题。同时

对偏转二次风合理的偏转角度和一、二次风动量矩比以及适用煤质等提出建议。

Abstract

The influence of biased secondary air in concentrically and tangentially firing system upon the air dynamic field in furnace

slagging

and NOx emission etc. has been studied and approached

the problems needing to pay attention during design of biased secondary air being analysed. At the same time

recommendations for adopting reasonable biased angle of the said secondary air

and for momentum moment ratio of the primary and secondary air

as well as for suitable coal quality have been put forward.
