The cement clinker is ground with about 5 gypsum. Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the
Compared to fossil fuels, most alternative fuels have a larger particle size, higher volatile and moisture contents, and a lower heating value. This makes their use in cement kilns challenging, as burnout takes longer, and flame temperatures are reduced. An increased understanding of these issues, and how to overcome them, are necessary to ...
The sulphur introduced into the cement kiln from both sides, the kiln feed and kiln burner, is in chemically reduced form such as S 0, S 1, and S 2. These sulphur forms are oxidized to S 4 and S 6 in the kiln system. This oxidizing process consumes some oxygen quantity leading to a reduction in the amount of oxygen in the kiln system.

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

Abstract Cement production is one of the most energy intensive industrial processes in the world. In many world regions, energy cost is 50 to 60 of the direct production cost of cement. Energy cost is incurred due to the need for large quantities of thermal heat for the kiln, calcination and drying processes and electrical energy for operation of motors for grinding mills, fans, conveyers ...

The organic matter in sludge was the main source of VOCs in the flue gas. Part of sulfurous substances, such as sulfur dioxide, carbon disulfide, were from sulfurcontaining substances in the sludge, and the rest were from the kiln tail gas itself.
