Brief Introduction of Fluidized Bed Boil

2015-2-24 · The difference between CFB and BFB is the fluidization statement. The Model of a combustion boiler (CFB) from Kvaerner Poweris shown in fig. 4. Compare fig. 2 and fig. 4, we can find that the fluidization height in fig. 2 is less than 1/5 of boiler height, while the fluidization height in fig. 4 is approximately the height of boiler.

CYMIC boilers - using CFB technolo

CYMIC is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time. The wide size range of CYMIC covers boilers from 30 to …

CFB Combustion Control System for Multiple Fue

2011-5-13 · CFB Combustion Control System for Multiple Fuels (1) High Fuel Adaptability Because the combustion reaction proceeds in the entire furnace height direction and a circulating cir-cuit for the fluidized particles exists, the CFB boiler has a long reaction time of combustion. For this reason, its adaptability to diverse fuels is high, and
