FAF26.6-14-1 Maintenance of rotor of adjustable axial flow forced draft fan with movable blades

提供二次风,通过空气预热器后,一部分到燃烧器提供周界风,夹心风等,对喷燃器处的火焰有影响,同时可以冷却喷燃器.另一部分提供锅炉燃烧所需要的氧量.最后还有一部是提供SOFA和COFA风,调整燃烧使用.
SOFA叫分离燃尽风,这是降低发电厂烧锅炉时散发氧化氮的一种技术.

Provide secondary air, through the air preheater, part of the burner to provide perimeter wind, sandwich wind, etc., has an impact on the flame at the burner, and can cool the burner. The other part provides the oxygen needed for the boiler to burn. Finally, there is one that provides SOFA and COFA wind to adjust the use of combustion.

SOFA is called separation of exhaust air, which is a technology to reduce the emission of nitrogen oxide from power plant boilers.
