Circulating fluidized bed(CFB) boiler with biomass as fuel, adopting the basic technology independently developed by ZG,have been in commercial operation. There are introductionfocuses on biomass fired circulating fluidized bed boiler design principles,the biomass fired circulating fluidized bed boiler design specifications.
Biomass fired circulating fluidized bed boiler design principle
Generally, compared with coal, biomass has more oxygen, more chlorine and potassium, less carbon, aluminum, iron, titanium and sulfur, and sometimes more calcium. Some special elements in biomass should deserve special attention because the existence of them will be the reason for designing different type boilers from those for coal. The most important element in biomass is potassium, which may form a low melting point ash during combustion in a CFB boiler. The low melting point ash constituents can induce the formation of agglomerates in a CFB boiler, in addition to deposition and corrosion. Accumulation of the agglomerates composed of sand and ash particles bound by fused and glassy materials may lead to defluidization and unscheduled shutdown of a plant.
Biomass fired circulating fluidized bed boiler technology
CFB technology provides fuel flexibility in that it can burn wood biomass and high Btu fuels.
The 100% of CFB biomass boiler technology is capable of combusting a broad range of different biomass fuels,including wood biomass and other agriculture biomass.Furthermore,the technology ensures high steam parameters and enables biomass fired power plants to obtain high efficiency with emissions far below the limits.
