# ﻿Unit Of Measurement For Boiler Steam

• ### What is a Steam Boiler Feed Unit and How is the Receiver

Jan 18, 2021 · Boiler Feed Unit Operation. The operation of a boiler feed unit starts with the control of the pump. Unlike a condensate return unit, the boiler feed unit pump is controlled from an external source. Obviously, as a steam boiler fires and produces steam, the water level in the boiler drops.

Dec 13, 2010 · 250 BHP Boiler. 250(BHP) x 0.069 (gpm/BHP) x 10 (min) x 1.33(SF) = 229.425 . Because of the 10 minute multiplier used in calculating a boiler feed pump receiver for boilers 200 BHP and over, a very fast sizing estimate can be done by simply stating that 1 BHP = 1 gallon of gross receiver capacity.

• ### How to Calculate Boiler Steam Flows | Hunker

Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler.

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

• ### Unit Conversion--How to Calculate Boiler Horsepower

Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.
