A calcining system wherein raw material is preheated by raw material preheating device for preheating the raw material by contact with a gas, calcined in a rotary kiln and cooled in a planetary cooler; a portion of cooling gas used for cooling the calcined material in the planetary cooler and heated thereby is led through an air extracting duct to the raw material preheating device and the rest of the heated cooling gas is introduced into the rotary kiln: and exhaust gases from the rotary kiln is led to the raw material preheating device. Such calcining system further includes a first damper mounted in a duct for discharging the exhaust gas from the raw material preheating device, a temperature sensor for sensing the temperature of calcined material discharged through an outlet of the planetary cooler, control device for controlling the degree of opening of the first damper when the temperature sensed by the temperature sensor rises to a high level, a second damper mounted in the air extracting duct, a gas sensor for sensing a gas component capable of indicating the condition of combustion in the rotary kiln, and control device for controlling the degree of opening of the second damper so as to bring the value of the gas component sensed by the gas sensor to a predetermined level. The flow rate of the cooling air can be controlled independently of the control of the flow rate of the air combustion, so that the temperature of the calcined material at the outlet of the planetary cooler can be kept at a predetermined level selected arbitrarily and the combustion in the rotary kiln and the calciner can be stabilized irrespective of changes in the conditions of operation.

A heat exchanger including a separating chamber in the form of a prism having a substantially horizontal center axis and axially elongated. The separating chamber having a collecting chamber disposed beneath it has an inlet duct opening in the separating chamber and connected to one wall of the separating chamber, and an outlet duct opening in the separating chamber and connected to a wall of the separating chamber. The outlet duct may be connected to the wall to which the inlet duct is connected or to another wall parallel to the wall to which the inlet duct is connected. The inlet duct is positioned and oriented in such a manner that a stream of gas and particulate material is introduced therethrough into the separating chamber in a direction tangential to a spiral stream of gas and particulate material formed in the separating chamber, and the outlet duct is positioned and oriented in such a manner that a stream of gas is discharged therethrough from the separating chamber in a direction tangential to the spiral stream of gas and particulate material formed in the separating chamber. The collecting chamber is disposed away from the spiral stream of gas and particulate material formed in the separating chamber.
