Quality of coal for Indian Cement Industry
Coal is the main fuel for the manufacture of cement in India, given the high cost and inadequate availability of oil and gas. The consumption of coal in dry process system ranges from 20-25per cent of clinker production. That means 0.20-0.25 T of coal is consumed to produce one tonne of clinker. The cement industry consumes about ten …

How can burning one ton of fuel create more than one ton …
Carbon dioxide is made of one carbon atom and two oxygen atoms. The carbon comes from the coal, but the oxygen comes from the air around it; during combustion, they react to create CO 2. That oxygen's extra mass is what allows one ton of fuel to produce more than a ton of CO 2. Exactly how much CO 2 a fuel emits depends …

Reducing Environmental Impacts of Cement and Concrete
About 1.6 tons of these raw materials are required to make 1 ton of cement. In 2009, over 78 million tons (71 million metric tons or mmt) of portland cement were produced in the U.S., and 3 billion tons (2.8 billion metric tons) were produced in the rest of the world. That's about 900 pounds (400 kg) of cement for every person on the …

Coal & steel
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified or ‘carbonised in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
