: A basic rule of thumb is one boiler hp equals the evaporation
: of 4.14 gal. of water in one hour.
: : I am trying to figure out how much horsepower my homebuilt water tube boiler makes. But all I have found so far is calculations based on one atmosphere.
: : This boiler, with the steam outlet open to the atmosphere still maintains 40psi. So going from this, when in operation, it will evaporate about 2.5 gallons of water per hour.
: : Feedwater temp is 70 deg-F
: : Thanks..
I would guess that your boiler is putting out .7 boiler horsepower. tim
