: How far above the tubes is your water level?
: What is the diameter of the boiler shell?
: Are you having problems with wet steam?
: Is the water level in the water gauge sight glass normal?
First of all, thanks for the replies.
I am doing some theoretical work here on the steam space that would be
available and the droplet size distribution in the entrainment under
steaming conditions in a packaged firetube boiler.
I have a shell diameter of 83 inches, 218 inches long.
The water level is 2-3 inches over the tubes and under steaming conditions
after taking into account the level swell, the steam space clearance can go
down to less than 4 inches, especially at low operating pressures.
