CFB Boiler

    (2) It adopts imported refractory steel to manufacture the vortex throat, which resists
          to high temperature an abrasion.

    (3) The recycle device is composed of two small U valves and uses them to recycle,
         which leads to uniform distribution of the recycled material and avoids the local
         accumulation on he grid plate so as not to influence the fluidization quality.

    (4) U-shape material recycle device can automatically balance the intake flow and the
          recycle flow without manual adjustment under operation

    (5) The water-cool wall pipes n funnel pipes attached to under body of hearth are all
          equipped with abrasion resistant device to assure the life expectancy of the
          heated part.

    (6) There is no heated surface of buried pipes which lay inside the hearth, which
          avoids the abrasion problems of buried pipes.

    (7) The fluidized bed hearth and vortex separator adopt fluidized bed abrasion-
          resistant molding bricks and fluidized bed abrasion-resistant casting material, to
          secure the long- term operation of boilers.

    (1) The hearth outlet is equipped with high-temperature vortex separator, which runs
          smooth and has a high separating rate.

The boiler structure is of (single) double-cylinder transversal natural circulation.

Main structural Features:

          Principle of Operation: put fuel coal and into fluidized combustion chamber, mix them up and ignite to burn. The gas solid separator attached to the hearth outlet filtrates the smoke with a large amount of granular material collected by the separator is sent to the main combustion chamber for circulating combustion through the recycle device.

          The CFB boiler is a new type boiler with high efficiency and low pollution.This boiler uses Circling Fluidized Bed burning system, has wide applicability for different coals, like soft coal, anthracite, poor quality coal, lignite, coal mud, biomass and etc... This series boilerp roduct is highly efficient (can reach 95-99%), energy-saving and environmentally-friendly.

          Especially for the high sulfur content, it can reduce the CO2 emission through add limestone in the boiler. It also can reduce the cauterization to the boiler and pollution to the environment. Moreover, the dust can be the mixing material for the cement.

                            
    This boiler is steam boiler of horizontal type, single drum with traveling chain grate. The threaded gas pipe is inside the boiler drum, and both side water-cooling wall rounds thumb flue in drum's belly. This structure protects effectively the boiler drum and avoids the belly directly radiated by fire. Boiler drum connects the two headers by two-side water-cooling wall. Four downcast pipes are foreside and rearward of boiler drum, and every pipe is led from drum to the header. Using this design, the drum and headers become a circulation loop together with the two sides water-cooling walls.
