Pressurized shell - water tube boiler
Pressurized shell - water tube boiler
(OP)
Hi All,
Is anyone here familiar with a manufacturer that offers water tube boilers (~50 MW) which have been designed for furnace gas pressures of 0.5 bar(g) shell side?
Thanks,
Howie

RE: Pressurized shell - water tube boiler
Your boiler/combustion needs are unique..
I would search for those boiler fabricators who specialize in waste-gas application for your high-pressure 0.5 bar design. Do you have a limit in mind for the gas side pressure drop and where will such a drop occur in the boiler ????
Do not be surprised if you do not get the thermal efficency that you expect from your unique design as most smaller watertube boilers are designed for + or - 30 IWC casing pressures. Your high-pressure design will probably require compromises which will decrease efficency.
Why must the gas stream be maintained at such a high pressure ? What is downstream of the boiler ?
An all-welded boiler boiler with membrane walls will probably be best..
Anyone else ?

I've dealt with the higher gas supply pressures, never ran into an overfire pressure that high.
