Read moreThis calculation translates the steam load (in pounds per hour) to 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.

Read moreJun 18, 2014 · Then, in 1967, they further reduced the Pickup Factor from 1.33 to 1.15, but only for hot water boilers. They let the factor for steam boiler sizing remain at 1.33 because steam piping is bigger than hot water piping. This is because steam is bigger than water. There's one problem here, though. Steam pipes contain hardly any water.

Read moreBoiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as maximum load. If the load varies from hour to hour, it operates at a varying load.Load and load variations can influence the amount of chemicals required for treatment and the treatment controls required.
