Improve Your Boiler's Combustion Efficiency

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

How to Calculate Boiler Steam Flows | Hunker

Modern power plants have huge boilers to feed turbine generators. 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.

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
