It is the boiler that uses a specific technology called “Circulating Fluidized Bed Combustion (CFBC)”. The fuel is burnt in a bed of hot particles maintained in flowing air. At adequately high air speed, the bed acts as a fluid resulting in rapid mixing of the particles. The fluidized action promotes complete fuel combustion at relatively low temperatures, and provides a means to transfer combustion heat efficiently from the bed to the steam tubes.
Boiler in which coal is burnt in an environment of high concentration of bed material (mineral matter) derived from combustion of coal retained by using cyclone / other means. This bed material is fluidized by primary air (a part of combustion air). The high concentration of bed material along with staged air supply ensures that bulk combustion temperatures do not exceed 950°C making it environment friendly (lesser production of NOx) means of utilizing coal.
ZBG circulating fluidized bed combustion boiler is the power industry's large-scale thermal energy equipment for thermal power generation and industrial utilization. The boiler with its simplified, cost-effective and efficient design provides improved performance. Benefits include high combustion efficiency, high reliability and availability, low maintenance costs, reduced erosion, enormous fuel flexibility and low emissions.
