摘要: Rotary kilns are used in many industrial processes ranging from cement manufacturing to waste incineration. The operating conditions vary widely depending on the process. While there models available within literature and industry, wide range of justifies further modeling work improve understanding taking place kiln. kiln being studied this produces calcium aluminate cements (CAC). In a first stage project, CFD empty model was successfully counteract ring formation partner’s rotary However, that did not take into account solids processed present describes phenomena granular bed links it observed productivity increase. A validated is developed different approaches found literature. Simplified sintering reaction kinetics proposed by considering experimental X-Ray Diffraction data handed our Industrial Partner information reported combined use simulate two sets process unique chemistry aluminates. By combining aspects for gas phase solid phase, accuracy improved consequence occurring better understood.
