Advanced Pulverized Coal Injection Technology and

In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column. The capacity of the furnace to consume ...

solutions for of rotary kiln failures in operation

When the coal powder falls to a certain extent, the combustion is fierce and the shooting phenomenon occurs. The method of prevention is to increase the ignition temperature as much as possible, reduce the amount of coal used, and shorten the ignition time. Excessive pulverized coal in the kiln before ignition, it is easy to appear after firing.
