- Cement production involves preparing a raw material mix that is burned at 1450 ⁰C in a direct-fired rotatory kiln to produce cement clinker. In this paper, a stable kiln operation has been referred to as a stable burning and constant high product quality. For the burning, conventional fuels such as coal and petcoke are partially replaced with alternative fuels. Properties of alternative fuels like water content, particle size and higher heating value in RDF (Refuse derived fuel), TDF (Tyre derived fuel) and MDM (Meat and bone meal) disturb the establishment of an ideal flame, which affects the burning and product quality. The chemistry of the fuels also influences the product quality as the ash is incorporated in the cement clinker. Evaporation and heavy condensation of volatiles from alternative fuels hinder the streams of gas and material in the kiln system. This paper summarises some experiences cement manufacturers can consider when operating with alternative fuels.
