Coal in the cement industry

In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing. In direct firing system, coal is milled on line and is directly fed to the kiln. The primary air is used to dry the coal. High moisture coal is not suitable for direct firing,

Cement Kilns: Firing systems Cement Plants and Kilns in

The use of pulverised coal for firing industrial furnaces was pioneered in the cement industry, and the perfection of the technique was a critical factor in the development of the rotary kiln in the 1890s. The desired requirement was for a system that could make cheap coal into a direct replacement for the more expensive fuel oil previously used.

cement plant with coal firing to minimise cost

Re: Replacing coal by natural gas in kilns. There are at least 2 reasons why cement kilns fired with natural gas are less productive than those fired with solid fuels: (i) the combustion product gas volume is higher with natural gas due to its higher hydrogen content, therefore the effective capacity of the induced draft fan of the kiln is reduced, and (ii) the emissivity of a gas flame is

Cement Plants: Coal

London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was

Alternative Fuels in Cement Manufacturing IntechOpen

Nov 18, 2010 Well-established technology, on the one hand, allows the rotary kiln of any cement plant to be fired with low-volatile fuels such as petcoke, low-volatile bituminous coal, and anthracite, without problem (Nielsen et al., 1986). On the other hand, high volatile-low calorific value alternative fuels have limited use in the kiln primary firing

Cofiring Wikipedia

Origin. Co-firing (also referred to as complementary firing or co-combustion) is the combustion of two different fuels in the same combustion system. Fuels can be solid fuels, liquid fuels or gaseous, and its source either fossil or renewable.Therefore, use of heavy fuel oil assisting coal power stations may technically be considered co-firing. However, the term co-firing is used in the

function of coal mill used in cement plant

Cement kiln Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
