1.\tWide adaptability of fuel

In Circulating Fluidized Bed Boiler, fuel occupies 3% of bed materials only, and the remains are incombustible solid particles. With special hydrodynamic force features, the gas-solid and solid-solid are mixed well in the circulating fluidized 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 isn’t 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.

2.\tHigh combustion efficiency

The basic difference between Circulating Fluidized Bed Boiler and other boilers is combustion system. The former is composed of combustor, material collector and back-feeder. High-temperature material collector by air flow, then materials collected enters into back-feeder, through which are transported to combustor to conduct several circulating combustion. So the efficiency of combustion is higher.

3.\tWide scope of load control and fast load control

The load often changes in the operation of boiler. When the loaf is lower below 70%, the combustion efficiency and heat efficiency of other 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 mass of return materials. Thus, its load can be adjusted within 30%-110%; in addition, the regulation speed of circulating fluidized bed boiler is also fast due to high air velocity of cross-section and controllable heat absorption, which can reaches 4% per min. generally.
