Proper sizing of Boiler Feedwater System

So a 500 HP boiler will need a pump capable of delivering 50 gpm. An 800 HP boiler will need an 80 gpm pump. The next step is to determine the proper discharge of the pump. ASME code requires that you furnish feedwater to your boiler at 3% higher than what the relief valve setting is on the boiler.
