pulverization of coal in a steel manufacturing plant

Coal pulverisation The Nature Of Science

coal has been reduced to the desired fine powder. Some power stations crush coal into fine dust in pulverising mills. These mills work by repeatedly dropping massive steel balls on to the coal until it is crushed into fine coal dust. The steel balls used at Drax, for example, are hollow, about 73 cm in diameter, and weigh 1.4 tonnes each. Each pulverising mill contains 10 of these balls, and

Pulverised Coal - an overview ScienceDirect Topics

Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or “races.” The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

Metallurgical Coal - Steel 360

06/12/2014  The following are major property parameters those determine the quality of Metallurgical Coal. 1. Total Moisture (TM): TM is to be limited to 10% maximum, in as received condition. High moisture creates handling problem and lowers available carbon. 2. Hardgrove Grindability Index (HGI): It provides a criterion of the ease of pulverization of coal. Ease of grinding is an important economic

CO 2 abatement in the iron and steel industry

Manufacturing steel is an energy- and carbon-intensive process and therefore a major contributor to global anthropogenic CO 2emissions. The iron and steel industry is the second largest industrial user of energy, consuming 616 Mtoe (25.8 EJ) in 2007 (IEA, 2010b), and is the largest industrial source of direct CO 2emissions (2.3 Gt in 2007 ...

Coal-fired power plants using pulverized coal or lignite as fuel generate large quantities of fly-ash as a by-product. With the increase in commissioning of several super thermal power plants with large capacity and with the increasing use of low grade coal of high ash content, the amount of generation of ash from them is becoming very large. This poses serious ecological problems. Most of the ash

How we make steel British Steel

This carbonisation process removes impurities, like coal tar and coal gas, to produce coke. The red-hot coke is pushed from the side of each oven and quenched with water before being transferred by conveyor to the blast furnaces. Additional raw materials are processed at Scunthorpe’s sinter plant, which forms an iron-rich feedstock for the blast furnaces. The ingredients – iron ore, coke ...
