ABSTRACT:
A method of controlling the heating gases in a kiln having a firing zone and at least one adjacent zone which, for example, may be a preheating zone and/or an after-heating zone, comprises directing combustion products into the firing zone to generate high temperature gases therein and withdrawing a portion of the gases generated after giving up some of the heat in the firing zone upwardly through an exhaust gas flue and sensing the temperature in at least one select location in said kiln and regulating the quantity of gases withdrawn in accordance with the temperature which is sensed. The kiln advantageously includes a preheating zone before the firing zone and an afterheating zone thereafter arranged in a straight line. Burners are arranged to fire downwardly in the firing zone and all of the zones are connected to discharge through a flue. The flue is provided with one or several control elements for regulating the rate of withdrawal of the flue gases which, for example, includes a controllable damper or a controllable circulating fan. A temperature sensing device, such as a thermocouple, is advantageously located in the preheating zone to control either the operation of the fan or the damper in accordance with the temperature sensed in the preheating zone. In addition, or alternatively, a temperature sensing device is located in the afterheating zone for controlling a withdrawal fan for gases connected directly to the afterheating zone. The control may also operate to control the air supplied to the furnace as a means for regulating the temperature in the firing zone and, consequently, in the preheating and afterheating zones.
