Circulating fluidized bed combustion (CFBC) uses high velocity air or gas to circulate bed material and maintain particles in suspension. This allows for continuous burning of fuel without a fixed combustion zone. CFBC boilers can be classified based on the type of separator used and operating temperature. Key advantages include fuel flexibility, low emissions, and ability to …
