Cement Dust an overview ScienceDirect Topics

1 Dust consisting of solid particles that are a entrained by process gases directly from the material being handled or processed like cement dust or grain from grain elevators b direct offspring of a parent material undergoing a mechanical operation like sawdust from woodworking and c entrained materials used in a mechanical operation like sand from sandblasting

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector In the rising process it comes into full contact with the falling limestone slurry sprayed by the spray SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column

HAZARDOUS LOCATION CLASSIFICATION Hazardous Locations consist of areas where there is the potential for a fire or explosion due to electrical equipment that is in operation in this area with a reaction to flammable or ignitable gases liquids vapors combustible dusts fibers or flyings The need for ExplosionProof equipment then arises due
