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. In addition, you must take into consideration any pressure drops between the pump and the boiler.

The Feedtank and Feedwater Conditioning | Spirax Sarco

The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.
