A controller for a clinker cooler for cooling high temperature clinker supplied from a rotary kiln by controlling the quantity of high temperature clinker cooling air at a constant value comprising maintaining the pressure at the rear side of a baffle plate mounted in the cooler constant by varying the opening of a damper of a cooler exhaust fan and the rotating speed of the cooler exhaust fan, and controlling the pressure of a kiln outlet hood by the quantity of clinker cooling air of the all air chambers of the cooler except for the first chamber on the kiln side of the baffle plate. Thus, the variations in the cooler exhaust amount and the secondary air flow rate occurring in the prior-art control means are reduced to stabilize the steps, to improve the quality of the clinker and to reduce the thermal quantity consumption per unit. |
