Steam Calculators: Boiler Calculator
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Gross and Net Efficiency Boiler Services Ltd
2020-3-13·We'll calculate the efficiency, discounting the latent heat, and call it net efficiency. So a boiler with a gross efficiency of 82% becomes a boiler with a net efficiency of 91%. Fantastic! That looks much better and we can now tell the public our boilers are 91% efficient. Well, where one manufacturer went, all the others had to follow or lose

Understanding Boiler Stack Losses - Forbes Marshall
A common trend observed is, as boiler is operated continuously, the measured outlet temperature of flue gases increases. After operation for a few months, significant rise in flue gas temperature and hence stack losses is observed. The reason behind this is, as a boiler is operated, scales are formed on the boiler

How to Calculate Gas Consumption in a Gas Burner |
Adjust for the burner efficiency by dividing consumption at 100 percent efficiency by the burner efficiency rating. For a burner that is 95-percent efficient, divide by 0.95. In the example: 40,000 BTU divided by 1,075 = 37.21. Adjusting for burner efficiency: 37.21 divided by 0.95 = 39.17 cubic feet of natural gas consumed in one hour.

How is Combustion Efficiency calculated? | Kane
Typically for a natural gas boiler oxygen readings may be in the range 3% to 5%, for an oil boiler 5% to 8% and for a coal fired boiler 8% to 10%. The combustion efficiency of modern condensing gas boiler can theoretically be over 100% as heat is extracted from the incoming air. A traditional brick built coal fired boiler may only be 50% efficient.

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.

Efficiency is the percentage of output from the input. No boiler is 100% efficient, as the boiler itself requires some energy to operate, and even the most efficient condenser boiler will inevitably lose a bit of heat to the atmosphere. But at around 90% efficiency, most modern boilers do a
