The application and effects of the wet plate-type dedusting technology in converter gas dedusting of the Gas Power Plant are described, and notable problems in use are raised.

Appropriate choice of top draft hood type is a key point for the modification project of secondary dedusting of converter off-gas at Xingtai Steelmaking Plant.

Problems and solutions in actual applications were discussed. A proposal for cement plant dedusting system design and analysis is provided.
