A review of some operation and maintenance issues of CFBC ...

While the use of CFB boiler has grown greatly, its operational availability has not been very attractive in some parts of the world. Ideally, CFB boiler is a relatively stable and trouble free technology, but in some parts of the world CFB boilers are facing more than expected share of outage reducing the boiler availability to as low as 60%.

How Circulating Fluidized Bed Boilers Work?

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert ...

B&W PGG IR-CFB: Operating Experience and New Developments

than CFB boilers with cooled cyclones. The start-up time for B&W PGG CFB boilers is not limited by the rate of temperature rise of the refractory; instead it is limited by adding heat to the pressure parts, like all other non-fluid bed boiler technologies. Low maintenance A distinct feature of B&W PGG IR-CFB boilers is low maintenance.
