    CFB Coal Fired Boiler

    Product Description

    CFB boiler (Circulating Fluidized Bed Boiler) features good coal adaptation, safe and reliable operation, high performance and energy saving. The ash may be used as the admixture of cement, decreasing environmental pollution and increasing economic benefit.

    CFB boiler can burn various fuels, such as soft coal, anthracite coal, lean coal, lignite, gangue, sludge, petroleum coke, biomass (wood chip, bagasse, straw, palm husk, rice husk, etc.)

    CFB boilers are specially designed and optimized for applications to produce medium and high pressure steam or hot water with rated evaporation capacity from 35 to 440 ton/hr and rated pressure from 3.82 to 9.8 MPa. The design heat efficiency of CFB boilers is up to 87~90%.

    Features:

    1. Burning efficiency reaches 95%-99%, high burning rate, heat efficiency above 87%.

    2. Energy-saving, high efficiency, high flexibility of fuel, which can satisfy the burning of many kinds of fuel.

    3. Limestone can be added in bed material during burning process reacts with SO2 of flue formulates sulphate, desulphuration can satisfy environment protection

    4. Reasonable wind distribution and low temperature or furnace can control formulation of NOx and really reach environment protection.

    5. Big adjusting range load can be adjusted to 30-110%.

    6. High automatic control makes boilers running safely and economically in long term.

    7. Adopt upper exhaust high temperature cyclone separated device, high collection of bed material.

    8. High heat transfer efficiency, high ability of overload.

    Application:

    CFB boilers are widely used for power generation in chemical industry, paper making industry, textile industry, food and drinking industry, pharmaceuticals industry, sugar refinery, tire factory, palm oil factory, alcohol plant, etc.
