Circulating Fluidized Bed Boiler - Chinaprice: 400000.00 Dollar US$
In circulating fluidized bed boiler, fuel occupies 3%of bed materials only, and the remain are incombustible solid particles.With special hydrodynamic force features, the gas-solid and solid-solid are mixed well in the circulating fluided bed boiler, so after the fuel enters into hearth, it will be quickly mixed with large amount of bed materials, then fuel is heated to the ignition temperature, and simultaneously, the temperature of bed is not lower obviously.Therefore, all coals should be burnt efficiently in this boiler .if you change the coal in the operation, combustion equipment and boiler body would also get higher combustion efficiency without any modification .
2high efficiency combustion
The basic difference between circulating fluidized bed boiler and other boiler is combustion system.The former is composed of combustor, material collector and back-feeder.high temperature material accesses to material collector by air flow, then materials collected enters into back-feeder through which are transported to combustored to combustor to conduct serveral circulating combustion .so the efficiency of combustion is higher.
3wide scope of load control and fast load control
The load often changes in the operation of boiler .when the load is lower 70%, the combustion efficiency and heat efficiency of the boiler is lower obviously with unstable combustion, and sometimes normal burning cannot be maintained;
However, circulating fluidized bed boiler can improve only by adjusting coal supply, air dose and circulating fluidized bed boiler is also fast due to high air velocity of cross –section and controllable heat absption, which can raches 4%per min, generally
4clean combustion technique
Simple desulfurization can be conducted in the hearth by adding lime stone in the circulating fluidized bed boiler .When calciumsulfur mole ratio is 20, the desulfurization efficiency would reach to 80%;due to grading supply and low-temperature burning adopted in the operation, the generation of nox is lower.Therefore, it greatly reduces the discharge value of sox and nox, and improve the atmospheric and environmental quality.
5easy for the comprehensive utilization of ash
Circulating fluidized bed boiler belongs to low-temperature burnt. simultaneously, good after-combustion condition makes carbon content of ash lower, which is easy for the comprehensive utilization.
6Heating surface for immersed tubes not arranged in bed
Heating surface for immersed tubes not arranged in bed of circulating fluidizied bed boiler, thus avoiding the wear of heating surface for immersed tubes .in addition, due to there is no heating surface of immersed tubes, it is easy for starting and stopping the boiler, and also can be directly activated after long-time fired banked.
