22 11 2019 At present vertical coal mill has been applied to the blast furnace injection pulverized coal preparation system of many steel plants at home and abroad which has delivered a large number of high quality combustion pulverized coal powder to the steel mill which greatly reduced the steel plant energy consumption.
Pulverized Coal Injection PCI is a process that involves blowing large volumes of fine coal granules into the BF This provides a supplemental carbon source to speed up the production of metallic iron reducing the need for coke production As a result energy use and emissions can be reduced However as coke provides physical support and gas permeability in the BF its complete
Industry trends which could increase the probability of fires and explosions in coal pulverizing systems are l The increased use of coal by utilities which have no prior pulverized coal experience 2 The increased use of lower rank higher volatile content coals 3.
Pulverized coal injection PCI is a recognized method of controlling costs in iron making The blast furnace is a complex system so the replacement of coke with pulverized coal is not as simple as increasing the injection rates especially when one considers iron
Types of coal pulverizers Coal pulverizers may be classified by speed as follows Low Speed Medium Speed High Speed Low speed Ball and tube mills A ball mill is a pulverizer that consists of a horizontal rotating cylinder up to three diameters in length containing a charge of tumbling or cascading steel balls pebbles or rods.
The coal mill grinding system is an important part of the dry process cement manufacturing In cement plants we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination However due to the flammable and explosive characteristics of pulverized
