Thermal dynamical analysis on the calcine system of cement-precalcination kiln in Shangdong Lunan Cement Ltd.Co. was made in this paper, exergy and its analytical method were introduced.
Limestone is refined to produce calcium oxide, or quicklime, for cement, in a reaction known as calcination, which releases a lot of carbon in the form of CO2.
石灰石被提炼以生产用于水泥的氧化钙或生石灰, 在称煅烧的反应中,该反应以 CO2 的形式释放大量碳。
In Colombia, a product based on this technology was commercialized a few months ago, and in the Ivory Coast, the full-scale plant is being commissioned to calcine clays.
I saw another at work to calcine ice into gunpowder; who likewise showed me a treatise he had written concerning the malleability of fire, which he intended to publish.
And here in Switzerland, we have found that clays produce very reactive materials when they're calcined,that's to say heated to around 800 degrees Celsius, significantly lower than the 1,450 needed to produce cement.
We then take this calcined clay, and we add a bit of limestone -- but this time not heated, so no CO2 emissions -- and some cement, and this combination of limestone, calcined clay and cement, we call LC3.
