The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.

Evaporation of volatiles Volatile phases in the cement kiln are principally alkali sulfates, with a much smaller proportion of alkali chlorides. As the part-burned feed approaches the burning zone, these volatile phases are in liquid form and a proportion volatilizes, the remainder passing out of the kiln in the clinker as inclusions within the ...
