All in all, the coal fired CFB boiler manufactured by ZG Boiler uses great quality materials that can realize anti-wear in a large degree and longer the boiler service life. Circulating fluidized bed boiler can burn good quality or bad grade fuels, such as bituminous coal, anthracite coal, lignite coal, furnace slag, MSW, biomass and so on.
sulfur coals is inadequate and is expected to remain so. By shifting available low-sulfur coal to plants not meeting primary standards from plants which could burn higher sulfur coal and still meet the primary standards, some improvement in ambient air quality could be achieved. It is estimated that a shift of as much as 36 million tons could

Circulating Fluidized Bed (CFB) Coal Fired Steam Boilers. while by simply adjust coal air feeding and recycled material, the load of CFB can be adjusted in a range of 30-110%; the rate of load-adjusting is also rapid (generally 4% per minute) due to high section wind speed and easy control of heat absorption. Main products include wood
The calculation of the coal consumption for the 20 ton circulating fluidized bed boiler is complicated, the fuel and design efficiency are indispensable. The calculation of how much coal used in a CFB (circulating fluidized bed) boiler per day is beneficial to the selection of boiler, and also provides the convenience for customers to reserve
Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.
