Coal utilisation in the cement and concrete industries

Jan 01, 2013 As of 2009, world cement output was estimated at 304 billion tonnes (metric tons) 6 China represents 561% of the world’s output while the USA represents 20% 7 Fuel used by the US cement industry is 60% coal, 13% petroleum coke, and 3%, natural gas 8 According to the US Energy Information Administration (EIA), the manufacture of cement Coal is only used for burning the klin to 1400°c to produce the concrete The other method to produce concrete is by fly ash Which again is not coal but a by product of burning coal which flies out and is collected using electrostatic precipitation So whatever coal floats your boat to reach 1400° or to make fly ash will serve the purposeWhich type of coal use by cement industryDec 01, 2009 asuming a coal of very low heat value, 5500 kcal/kg as indicated by Mr ovancantfort, leads to a coal economy of 144 480 000 000 / 5500 = kg coal this is 26269 tons coal Therefore, even assuming a very poor coal, we get a 20% lower coal economy ReplyCOAL CONSUMPTION Page 1 of 1 International Cement ReviewAug 09, 2019 Building enough wind turbines to supply half the world’s electricity would require nearly two billion tons of coal to produce the concrete and steel, along with two billion barrels of oil to make the composite blades More than 90% of the world’s solar panels are built in Asia on coal One Wind Turbine Takes 900 Tons of Steel , 2500 Tons Of Aug 22, 2019 To supply half the world’s electricity using wind turbines would require nearly two billion tons of coal to produce the concrete and steel and two billion barrels of oil to make the blades And, most (over 90 percent) of the world’s solar panels are built in Asia with electric power heavily fueled by coalThe Physical Impossibility of Renewable Energy Meeting the
