Steelmaking(dry dedusting) Measuring Points and Solutions

The other way to purify and recycle coal gas is dry dedusting. Compared with wet dedusting, dry dedusting has higher purifying efficiency with no secondary pollution and sewage processing; higher coal gas calorific value and recycling dust can be used directly to save energy. Therefore, the dry dedusting method has higher economic and environmental benefits.
