A typical furnace is rated at 100,000 or 80,000 BTU per hour, but furnaces might be as small as 40,000 or as large as more than 200,000 BTU. A 90 percent high-efficiency rated at 60,000 BTU will
750 tons for 25 boilers divided by 24 hours is about 1.25 tons an hour per boiler or 2500 pounds an hour. Coal depending on grade yields roughly 10000btu per pound so that would place the BTU input for each double sided boiler at 25,000,000 per hour. 33,472 BTUs equals 1 hp so If I divide 25,000,000 by 33,472 I get 747 HP.
Therefore if we assume that the boiler, when operating, burns oil for 65% of the time, then the amount of oil used is 1.48 Litres per hour (= 2.27L X 0.65). As the current cost of oil, including taxes, is approx. €0.81 per Litre, the approximate average fuel cost of running an oil boiler is €1.20 per hour.
A heating degree-day calculation, using the month of July as a factor, is a more precise way of estimating furnace size. Natural gas for a furnace is priced by the therm, or per 100,000 BTUs.
A British thermal unit is the amount of energy required to heat a pound of water by 1 degree Fahrenheit. This can vary slightly depending on the temperature of the water, therefore different estimates for the BTU exist. A BTU/hour is about 0.293 watts.
This is where the 500 btus per hour comes in. On average a sedentary worker in a building will add 500 btus per hour to ALL areas of the building whether it is hot or cold outside. This creates an issue in the winter when the perimeter of a building requires heating and the center of the building requires cooling.
So, I'm burning about 305,000 BTU of wood per heating day, with about 60% efficiency in my stove, delivering about 183,000 BTU. Assuming electricity is 100% efficient, this corresponds to 54 KWH per day (3413 BTU/hr per KW). Using my local winter post-tax rate of 7.8 cents per KWH, that's about $4.19 per day I'm not spending on heating my office.

For the low-pressure steam typically used in heating systems, that ratio is 1,194 BTUs for every pound of steam the system provides. If your boiler supplies 400 pounds of steam per hour, for example, you would multiply 400 pounds by 1,194 to arrive at a figure of 477,600 BTUs.
Conversion of units between 4 Ton Of Refrigeration (It) and Btu (International Table) Per Hour (4 and BTUIT/h) is the conversion between different units of measurement, in this case it's 4 Ton Of Refrigeration (It) and Btu (International Table) Per Hour, for the same quantity, typically through multiplicative conversion factors ( and BTUIT/h).
Boiler 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.
The cooling BTU multiplier is 4.5. Here's the cooling BTU math: 905 CFM x 4.87 BTU per lb. x 4.5 = 19,833 Total System BTUs. Compare the delivered Cooling BTUs you just calculated of 19,833 to the 3-ton system rated BTUs of 36,000 to find your cooling system is only delivering 55% of the cooling system's rated BTUs.
