In fluidized bed combustion (FBC) ( Fig. 4 ), crushed coal, 5–10 mm in particle size, is burned in a 1000-mm-deep bed of 0.5- to 3.0-mm particles consisting mainly of additive sorbents (limestone or dolomite) and coal ash. The bed is fluidized by a blast of air through a distributor plate at the bottom of the bed.

Grate boilers are suitable for many types of fuels: coal, wood fuels, waste fuels, peat and even straw. One common problem related to grate firing is melting of the biomass ash on the grate ...

Valmet has been developed circulating fluidized bed (CFB) boilers for over 30 years, and has delivered dozens of biomass or biomass co-firing projects during the last 25 years. In the 1980s CFBs were only coal firing equipment. Today they are multifuel firing equipment, and sometimes even biomass boilers.

CFB is the only boiler technology providing both high-efficiency combustion and vast fuel-flexibility at the same time. The multi-fuel CFB can co-fire a wide range of fuels, with up to biomass or RDF streams. 2 High-efficiency and reliability in the harshest conditions. By recirculating the bed material through a cyclone, CFB technology ...

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 …
