circulating fluidized bed combustion - an overview

Thus, the thermal efficiency of a CFBC boiler is 34% lower than an equivalent-size pulverized coal-fired boiler. The operating performance of the CFBC boiler shows that whenever there is a need to increase load on the boiler it can be achieved by raising the bed temperature and keeping the bed material height unchanged ( Figure 5.19 ) [15]
