What is the capacity of a burner? Is it the same as a boiler

Burner capacity is generally measured in BTU/hr (heat input rate) Boiler capacity is typically measured as #/hr of steam. (at rated steam conditions - most commonly 1005 deg F and 1800 to 3500 PSIG.) This is the steam output rate. There may be one or more burners per boiler.

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat loss. The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel.

Ways to Calculate CFB Boiler Efficiency

Thermal efficiency measures how well a CFB boilers heat exchanger transfers heat from the combustion process to the water or steam in the boiler. A simple ratio expressed as a percentage, thermal efficiency is basically the input energy transferred to the water or steam heating process divided by the output energy of the combustion process.
