Circulating Fluidized Boiler

Circulating fluidized boiler is one of the clean coal combustion technologies with the be commercialized degree. It has obvious advantage in burning low quality fuels with high ash content, low volatile and high sulphur content. And it is the best option for self-prepared power station of enterprise and medium-sized thermal power plant. It has development advanced technologies such as water cooling cyclone separation (independent patent) , special anti-wearing structure for furnace, secondary wind-optimization combustion and gas film cooling ignition etc. It has a series of circulating fluidized bed boiler from 35t/h to 670t/h dominated by "water cooling cyclone separator, water cooling square-type separator and heat-insulated cyclone separator. THECHNICAL FEATURES OF CIRCULATIONG FLUIDIZED BED BOILER WITH WATER COOLING SEPARATOR: •With optimized core tube structure that is separated at high temperature with high separation efficiency. •Thickness of refractory material of water cooling separator is 60mm. The test cycle for the furnace wall material of separator may be 4 years or above due to water cooling, which saves investment cost in water and repair cost. •Coals with low volatility may not produce coking or blockage of return valve. •Expansion and sealing can be well solved as both separator and water wall adopt suspension structure. •Boiler can be quickly started with low oil consumption at ignition and convenient load adjustment.
