Abstract:

The desulphurization demister of Shangqiu Yudong Power Generation Company Limited was blocked frequently. The fault was inspected and analyzed,and

it was determined that the main reasons of frequent blockage of the demister are that the original gas flue and the cleaned gas flue are too short, and the

arrangement of the wash water tube and the angle of the jet nozzle of the demister are irrational. A suggestion on reformation of the wash water system was

put forward. The suggestion had been implemented, and favorable economic benefit was obtained.
