09/05/2012#0183;#32;Cement manufacturing is highly energy and emissionsintensive because of the extreme heat required to produce it. Producing a ton of cement requires million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to look to reduce greenhouse gas emissions.
Coalderived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heatup of the charge, the fuel''s volatiles are lost without ignition, so wasting up to half the fuel''s calorific value.

Many industries use coal to manufacture certain products. Some of the popular industries which make use of coal are the cement industry, paper and aluminium industry, chemical and pharma industry amongst others. Coal provides numerous raw materials like benozle, coal tar, sulphate of ammonia, creosote, etc. to chemical industries. Coal is mostly used as a source of energy is most of the industries
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal also known as thermal coal is mainly used in power generation. Coking coal also known as metallurgical coal
18/11/2010#0183;#32;Historically, the primary fuel used in cement industry is coal. A wide range of other fuels such as gas, oil, liquid waste materials, solid waste materials and petroleum coke have all been successfully used as sources of energy for firing cementmaking kilns,

To resolve this problem, the role of coal on cement making and possible improvements in coal quality and consistency have been explored (Kumar, 1994). The cement industry is the third largest user of coal after the steel and power industries and it consumes more than 5% of total coal produced in India.

An operating Portland cement manufacturing plant (Lafarge North Americas Roberta Plant in Calera, Alabama) served as facility for a series of trial burns to replace coal at various substitution rates with biobased and waste fuels.
still be used in cement kilns. Coal is a combustible carbonaceous rock, containing many kinds of organinc and inorganic material, formed from accumulated vegetable matter that has been altered by decay and various amounts of heat and pressure over millions of years[89]. Coal
20/11/2019#0183;#32;Making cement green. One of the most straightforward ways of putting a dent in cements carbon emissions would be to find cleanerburning fuels that are capable of heating a cement kiln.
Coal is used as an energy source in cement production. Large amounts of energy are required to produce cement. It takes about 200 kg of coal to produce one tonne of cement and about 300400 kg of cement is needed to produce one cubic metre of concrete.
London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was
17/07/2018#0183;#32;Coal waste used to create sustainable concrete Scientists have created a sustainable alternative to traditional concrete using coal fly ash, a waste product of coalbased electricity generation. The advance tackles two major environmental problems at once by making use of coal production waste and by significantly reducing the environmental impact of concrete production.
18/11/2010#0183;#32;Historically, the primary fuel used in cement industry is coal. A wide range of other fuels such as gas, oil, liquid waste materials, solid waste materials and petroleum coke have all been successfully used as sources of energy for firing cementmaking kilns, either on their own or in various combinations.
18/06/2020#0183;#32;Coal is used to burn raw material to clinkering temp. 1450 degree centigrade. Low grade coal can be used for cement manufacturing but it will need high grade of limestone for good quality cement. you can say low grade coal need high grade limestone
Coal is used as an energy source in cement production. Cement is made by combining limestone, silica, iron oxide and alumina in a high temperature kiln, often fuelled by coal, to a temperature of about 1450#176;C. This transforms the into a substance known as
