The trend of increasing the capacity of cement kilns has slowed down in recent years — maximum clinker output still lies between 12,000 and 13,000 tpd. Burning and cooling technologies have progressed, especially with respect to burners specifically designed for the co-incineration of high levels of alternative fuels.

As a central unit, the rotary kiln is the most energy-consuming and energy-wasting unit throughout cement production. Thus, the rotary kiln is the most expensive part of a cement plant, which significantly consumes fuel and directly affects the final product price (Bui, Tarasiewicz, and Charette Citation 1982; Radwan Citation 2012). All these ...

1 Fuels will still have to be burnt in a rotary kiln in the future. The burner of the future will therefore look – at least on the surface - much like today's; 2 The main burner will remain at the 'heart' of the cement plant. However, the cement plant has grown since the adoption of alternative fuels.
