coal boiler cyclone design

Cyclone furnace | Article about cyclone furnace by The Free

Bailey's boiler meters, his pioneering work on watercooled walls for furnaces, and the design of the cyclone furnace for pulverized coal--he held more than 100 patents over his 60-year career--were the product of his singular focus: how to burn coal more efficiently in boilers.

FACTORS THAT AFFECT CFBC BOILER FURNACE TUBE EROSION

Cyclone collection efficiency / cut off particle size- the design of cyclone is critical for low ash coals. When the fines leave the furnace, the combustion temperature would raise. Fly ash particle sieve analysis proves the efficiency of cyclone. Radial and volute entry configurations have been used by boiler maker.

Modern Boiler Types and Applications

Cyclone-fired boilers are used for coals with a low ash fusion temperature, which are difficult to use with a PCF boiler. 80-90% of the ash leaves the bottom of the boiler as a molten slag, thus reducing the load of fly ash passing through the heat transfer sections to the precipitator or fabric filter to just 10-20% of that present.
