Abstract
A method and apparatus for automatically controlling a carbon bake furnace to thereby reduce uniformly baked anodes is disclosed. In its method aspects, the invention contemplates the use of flue and pit temperatures to produce a control signal to operate a valve for varying the air fuel mixture of a burner associated with said valve. In its apparatus aspects, the invention utilizes a plurality of infrared detectors to measure the pit and flue temperatures. The signals produced by these sensors are fed to a computer which produces a control signal for operating a valve associated with at least one of a plurality of burners which is to have its air/fuel ratio adjusted to thus adjust the temperature in the pit heated by the selected burner to a desired target temperature.
