The main reasons to the rotary air pre-heater secondary combustion are related to unstable oil gun combustion, internal oil leakage and insufficient soot-blower steam pressure, etc.
锅炉回转式空气预热器发生二次燃烧的主要原因与油枪燃烧不稳定、内部有漏油和吹灰蒸汽压力不够等相关。

The burner adopts a separated burner and the air used for combustion is pre-heater.
燃烧机采用了分体式燃烧机，并用空预热器加热了燃烧用空气。
