Cement calciners are pyroprocessing units found in modern cement plants. Inside of them occurs a strong endothermic reaction known as the calcination process, and the combustion of pulverized solid fuels.

Apr 12, 2019The inside of a pre-calciner (preheater) tower at a cement plant. In this system the hot combustion gasses from the kiln are passed up through the falling raw meal in a series of cyclones. The average preheater typically produces a hot feed that is 20% calcined when it enters the kiln, increasing the clinker output of the plant.

Aug 12, 2014The cement plant controlled the calciner temperature by adjusting the flow of petcoke. In order to estimate the amount of RDF fired, the percentage of fuel input to each calciner originating from petcoke is calculated by Equation 2. The percentage remaining in the calciner after firing corresponds to RDF. Two tests were performed at the plant:
