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.
Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone.
