大容量锅炉四角切圆燃烧时的烟温偏差问题

Discussion on Gas Temperature Deviation of Large Boiler with Tangential Firing

论述了烟温偏差的基本情况，剖析了产生烟温偏差的原因，提出了炉内存在向上倾斜的四股射流火焰是大容量锅炉烟温偏差增大的根本原因和减少烟温偏差的方向及措施。

The basic situation of gas temperature deviation is described. Reasons of the gas temperature deviation are analyzed. There are four jet flames in the furnace of large capacity boiler and it leads to bigger gas temperature deviation. Some measures to protect the bigger temperature are proposed.
