stove waste gas application in pulverized coal mill

Stove Waste Gas Application In Pulverized Coal Mill

Pulverized coal injection is a method for improving the performance of a blast furnace. The PCI method is based on the simple concept of primary air (termed the conveying gas ) carrying pulverized coal which injected through a lance to the tuyere (mid-bottom in let of a blast furnace), then mixed with secondary hot air (termed the blast ) supplied through a blowpipe in the tuyere and then.
