  • Coal for cement: Present and future trends

    Mar 01, 2016· Thermal efficiency (100% 12%) x 385.6Mt = 339.2Mt. Even if the cement industry grows significantly in the next 34 years, relatively minor improvements to alternative fuel rate, clinker factor and thermal efficiency may mean that the sector will actually require around the same amount of coal as it does at present ~340Mt/yr.
