Catalytic residual boiler soot blower
Thread Content
What is the purpose of a set of nitrogen pipelines in the catalytic economizer soot blower valve assembly? Thank you!
It’s supposed to be used for backflow prevention, to avoid corrosion caused by condensate
Isn’t it a bit of a waste to use nitrogen? Usually, air is sufficient
It’s probably not for blowing dust. . . Backflow is possible. . . Here, we still experience dew point corrosion even with backflow of air; using nitrogen should help improve the situation
Nitrogen is used as a substitute for acetylene, as a soot-blowing medium, right?
It can’t be a dust-blowing medium; it should be backblowing. However, I’ve never seen nitrogen being used for backblowing. Before we used unpurified air, and now we draw air directly from the main air supply line – that saves energy
Is it definitely nitrogen? For backblowing, we also use air
Nitrogen is non-flammable; how can it be used as a soot-blowing medium?
