The Application of Electric Bag Filter Pre-coated Fly Ash to Large CFB Boilers

The composite electric bag in Diaobingshan 2×300 MW CFB boiler flue gas dust precipitator,combined with the inherent characteristics of the CFB boiler preset bed material,completely abandons the traditional pre-coated method,which costs time and resource,and with poor effect.A simple and practical fluidized bed material pre-coated plastering new technology is used,saving a lot cost and greatly shortening the boiler start-up time,thus eradicating the chronic problem brought about by electric bag during the start up.So it carries practical value.
