ABSTRACT:
The present control system and method for controlling the combustion chamber pressure in a non-linear combustion process is operative in relation to one or more combustion chambers each having a flue gas damper. In the case of a plurality of such chambers, the outlet duct associated with each chamber is connected to a common exhaust stack. This operation is in relation to a desired damper position control characteristic provided by a combination of process signals in a microprocessor computer apparatus. Information in the form of the combustion and pressure levels as supplied in an anticipative feed-forward control manner by a particular combustion chamber is utilized in conjunction with a variable gain characteristic determined by the actual position of the damper operative with that combustion chamber to determine the correct damper position for that chamber.
