Combustion of bark wood waste in fluidized boiler

Circulating Fluidized Bed Combustion Boiler System--ZBG

In the fluidized bed combustion boiler system, the bed material's large heat capacity enables burning moist and difficult fuel mixed combustion of different fuel is also possible. Applicable fuel: wood wastes (bark, chips, sawdust, etc.), coal, lignite, agriculture wastes (rice husks, orange peelings pulp, coffee spent, etc.), pellets (wood, paper, plastics), industrial wastes (fabrics, fibers

Boilers. A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction. Moreover, the fluid sand and fuel issuing out of the furnace are collected

A later innovation in wood firing is the fluidized bed combustion (FBC) boiler. A fluidized bedconsists of inert particles through which air is blown so that the bed behaves as a fluid. Wood residueenters in the space above the bed and burns both in suspension and in the bed. Because of the largethermal mass represented by the hot inert bed particles, fluidized beds can handle fuels with moisturecontents up to near 70 percent (total basis). Fluidized beds can also handle dirty fuels (up to 30 percentinert material). Wood fuel is pyrolyzed faster in a fluidized bed …

Fly ash from coal combustion in the CFB boiler - …

17/8/2015 · Among the frequently co-combusted bio-mass are: wood, wood chips, bark, straw, olive mill cake, and sunflower husks . The properties of fly ash from co-combustion depend greatly on the burning conditions (the kind of boiler, tem-perature of burning), the amount and chemical composition of the ash from coal and biomass, as well as the share of the biomass in the mixture with coal.
