Cement Kilns Firing systems. In rotary kilns, irrespective of the fuel used, the most obvious common feature of the firing system is the firing pipe (burner pipe) which passes through the kiln hood at the kilns hot end, arranged more or less along the kilns centre line, and through which the fuel is projected into the kiln at high velocity.

This means that an efficient kiln consuming 3.2 GJ per tonne of clinker will only take in 1216 kg of air per tonne of clinker - i.e. the air/clinker ratio is 1.216. Using this air alone in the cooler would result in a clinker temperature of 399 C, so the extra air needed to obtain a reasonable temperature is surplus to
