Air-Staged Combustion Characteristics of Pulverized Coal

It is of great importance to clarify the effect of the combustion temperature in actual boilers on air-staging combustion of coals. In this work, a novel vertical tandem-type drop-tube furnace system was set up, in which a temperature of as high as 1600 °C can be achieved. Experimental investigations were performed thoroughly with particular

Coal for Pulverized Coal Injection in Blast Furnace

Combustion rate – Decrease in combustion rate under the condition of high coal rate injection is not an unusual problem in BF with high rate of injection of coal. Although some unburned pulverized coal gets consumed by means of direct reduction in the BF, excessive unburned pulverized coal can cause a decrease in permeability in the furnace, inducing undesirable gas and temperature
