Steam generation

(OP)
Is there a calculation that adequately describes the " release area" or " disengagement area" necessary per boiler horsepower?  My cursory investigation indicates a wide range of surface areas described depending on the device.

RE: Steam generation

Do you mean the size of a safety relief valve for a boiler?  Check ASME Boiler and Pressure Vessel code.

RE: Steam generation

This, or something much like it was covered in a thread on this site some time ago.  Do a search on this site.

RE: Steam generation

lamonte,

It should be related to, or the same thing as, the calculation on a flash tank to minimize entrainment of liquid droplets.  If memory serves me right, you size for an allowable velocity, U, based on

U = K x ((dl - dv)/dv)1/2

dl is liquid density
dv is liquid density
K is a sizing constant depending on the application

My experience is not with boilers, so the reference I look at is Perry's Chemical Engineers' Handbook.  The chapter on Liquid-Gas Systems.  You should try to research similar technology in the boiler field.

Good luck,
Latexman

RE: Steam generation

Correction.

dv is vapor density

Good luck,
Latexman
