How to Calculate Boiler Steam Flows | Hunker
Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

Boiler Ratings and Boiler Load - Alken-Murray
2007-3-24 · Boiler Ratings and Boiler Load . The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions.

What Size Boiler Is Needed Per Square Foot of a
Boiler size describes the heat output of a boiler in energy units, not the physical size of the boiler. Manufacturers measure boiler output in British thermal units (BTUs) per hour or boiler horsepower (BHP). BHP measurements usually only apply to very powerful and large capacity boilers, since one BHP equals 33,475 BTUs per hour.

The input is also used to determine the efficiency of the boiler for example; a boiler with an input of 150,000 Btu/hr and a gross output of 135,000 would have an estimated combustion efficiency of 135,000÷150,000= .90×100=90% eff. Next we have the boiler output, which can be listed in several ways.

How do I determine what capacity boiler I need? |
Like all good guidelines, these should be used with extreme caution. Remember that we are talking about the output capacity of the boiler rather than the input capacity or firing rate. Most of the comfort complaints people have with home heating systems have more to do with uneven or inadequate distribution than inadequate capacity.
