coal specification for use in cement industry. Coal Cement World Coal Association. 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.
Cement production has advanced greatly in the last few decades. the traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas.
For instance, in the steel industry coal is used as a raw material to produce coal coke. 2. energy consumed as a fuel - the steel industry used over 1.1 quadrillion btu quads of energy as fuel in 2006. nearly all of the industrys fuel consumption came from one

Apr 02, 2019nbsp018332the big picture coal is the most emissions-intensive fossil fuel, and steel and cement production account for more than 20 of the worlds use. while options exist to reduce or eliminate coal from those processes, many of the necessary technologies require policies, incentives and new markets to bring down the costs of commercial deployment.
To the extent that charcoal could be used in steel-making or cement-making around the world to replace coal, it is questionable whether this use of wood would be considered environmentally sustainable, especially if this huge shift in land use displaced food production.
