Petroleum coke has a high calorific value (up to 33,5 MJ/kg) and therefore may be partially (up to 25%) is used as an alternative fuel. Due to the excess temperature of the gas flow over the temperature of the material at approximately 750 °С, coke can be fed into the mill during grinding of raw slurry for wet process cement production. Burnable petroleum coke creates microportions material calcined at different temperatures and atmospheric gas, which leads to the formation of clinker with various properties of the individual phases of the clinker. The hydration of the clinker provides a dense structure and increased strength of the cement stone.
