A Survey on Circulating Fluidized Bed Combustion

Moreover slagging outside the furnace is more and cyclone separators are overheated. CFBC boilers with once through steam cycle has better efficiency when compared to the existing boilers as the CO2 content is reduced [39]. While using this, the evaporation and economizer duties are reduced and the superheat duty is increased.
