### Horsepower Formula - ScienceStruck

Mar 06, 2018· Horsepower Formula. Boiler horsepower (BHP) is a power unit used for measuring the power output of boilers. It was widely used in the past, though it's now mostly confined to North America. 1 Boiler Horsepower = 9,809.5 W One more unit used for power measurement is hydraulic horsepower.

Learn More### Boiler Horsepower - Engineering ToolBox

A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.

Learn More### Q1: What is the boiler efficiency? -

Then, we will reply you the followings concerning Boiler Efficiency which is closely related with the boiler saving energy. Definition of Boiler Efficiency is "The percentage of the total absorption heating value of outlet steam in the total supply heating value." In other word, it is a rate how the boiler runs efficiently.

Sizing a Boiler Feed Pump Receiver. The receiver tank should be able to hold five minutes worth of condensate for boilers up to 200 BHP and 10 minutes of condensate for boilers over 200 BHP. An additional 33 percent should be added as a safety factor. One BHP (Boiler Horsepower) will produce 0.069 gallons per minute of condensate.

Learn More### How to Calculate Boiler Heat Input Rate | Sciencing

The boiler's heat input rate is proportional to the rate at which the temperature of the water within it rises. The factor relating these rates is the specific heat capacity of water. Subtract the water's initial temperature from its temperature at the end of the period whose input rate you are calculating.

Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
