Circulating Fluidized Bed Boiler

ZBG Boiler Circulating Fluidized Bed Boilers, which is used in power plant. Fluidized beds suspend solid fuels in upward-blowing jets of air during the combustion process. The result is a turbulent mixing of gas and solids. The tumbling action, much like a bubbling fluid, provides more effective chemical reactions and heat transfer.


CFBC technology was adapted to burn petroleum coke and coal mining waste for power generation. CFB Boiler control emissions from roasting sulfate ores without the need for external emission controls. The mixing action of the fluidized bed brings the flue gases into contact with a sulfur-absorbing chemical,such as limestone or dolomite. More than 95% of the sulfur pollutants in the fuel can be captured inside the boiler by the sorbent.


Application

Chemical industry, plastics industry, coatings and automotive industries, bitumen industry, construction equipment industry, shipbuilding industry, washing, ironing, pharmaceutical industry, biotechnology, food industry etc,.
