Study on the Microstructure and Behaviour of Unburnt Pulverized Coal in BF

Abstract:

Using the sampling device for unburnt pulverized coal(UPC) before the tuyere and combining the UPC microscopic morphology which are in BF dust, there is a detailed study of the combustion process of coal before the tuyere. Analyze the behavior of the UPC for effective use and ineffective use in BF, and then get the conclusion, that it can relax the size of the PCI appropriately, and make it to produce proper UPC, which can participate in all kinds of reaction in BF, so that it can replace a part of coke; but in the slag and dust the UPC is hoped not too much.
