Effect of Bed Pressure Drop on Performance of a CFB Boiler

The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed (CFB) boiler was studied. By using the state specification design theory, the fluidization state of the gas−solids flow in the furnace of conventional CFB boilers was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality. Through

CFBC and BFBC of low-rank coals - ScienceDirect

Feb 22, 2009 · CFB uses coal crushed to sizes of around 3 to 6 mm. The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel. CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizing.

Progress of circulating fluidized bed combustion

The first lower energy consumption CFB boiler based on the re-specification of the fluidization state began commercial operational in 2007. As shown in Fig. 5, the field test results [] showed that with the pressure drop decrease from 7.3 to 3.2 kPa, the solid suspension density in the dilute zone was barely influenced due to the higher collection efficiency of the cyclones.

Nov 01, 2015 · From an efficiency point of view, fluidization with recycled CO 2 is preferred. CO 2, however, is a poor gasification agent. A better option would be to recycle "hot CO 2 ", i.e. flue gas withdrawn before condensation containing both CO 2 and H 2 O. The efficiency penalty for using "hot CO 2 " is smaller, estimated at below 0.2%.
