Coal is still used in approximately 90% of cement plants globally to deliver the energy needed for the heat inside the kiln Online coal analyzers using PGNAA technology are used to control the coal blend to a specific GCV in addition to the ash value of the coal as this adds raw materials to the process as well
Coal is a fossil fuel consisting mainly of carbonized, decayed, pre-historic plant matter It is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process The four main types of coal are lignite, sub-bituminous, bituminous, and anthracite Each .
The Calera cement can be used as a replacement for the Portland cement that is typically blended with rock and other material to make the concrete in everything from roads to buildings If the process can be made cost effective, it would eliminate the need for expensive carbon-sequestration and could make “clean coal” a possibility
