Circulating Fluidized Bed Combustion - an

In a CFBC unit, heat losses from the cyclone(s) are considerable. Thus, the thermal efficiency of a CFBC boiler is 3–4% 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] .

Circulating Fluidised Bed Combustion (CFBC)

Individual CFBC generating units are available with capacities up to 660MWe – and can also utilise supercritical generating technologies. Today, CFBC technology can be considered as a mature technology for power generation/co-generation and industrial-sized applications and is commercially available from multiple suppliers.

Developments in circulating fluidised bed

CFBC offers specific advantages over PCC, particularly in the utilisation of low quality coals, and mixtures of coal with other fuels, including wastes. Since its initial deployment, CFBC has continued to evolve. Recently, significant advances have been made in scaling-up the CFBC units and in the adoption of supercritical steam parameters.
