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.
1 pound of steam per hour = 970 B.T.U. per hour 1 square foot of equivalent steam radiation = 240 B.T.U. per hour 1 square foot of equivalent water radiation = 150 B.T.U. per hour INDUSTRIAL PUMPS The costs listed here are only indications of the average installed costs, since there are too many types of pumps and service condi-tions to provide really accurate estimates.

In the following equations, the operating cost of the boiler is CO per hour and the process requires S pounds/hour (lb/h) of steam. To deliver this much steam, it is necessary to actually generate (1+X)S lb/h of steam, where X is a factor typically ranging from 5 to 20%. So we already have two distinct equations to determine the cost of steam:
