    Ways to Calculate CFB Boiler Efficiency

    Thermal efficiency measures how well a CFB boiler’s 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.
