CFBC Boiler |authorSTREAM

CFBC boilers are generally claimed to be more economical than AFBC boilers for industrial application requiring more than 75 100 T/hr of steam CFBC requires huge mechanical cyclones to capture and recycle the large amount of bed material, which requires a tall boiler. A CFBC could be good choice if the following conditions are met. 1.

What Is The Working Principle of CFBC Boiler

What is the working principle of CFBC boiler? Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this

CFBC boiler process and their advantage over AFBC boiler

Sep 01, 2017· In CFBC boiler bed temperature is controlled by rate of recycling of fine materials. CFBC required large amount of mechanical cyclones to capture and recycle the solids particles, so normally CFBC boiler is taller than the AFBC boiler. CFBC boiler is generally more economical and its efficiency is more than 85%.
