Title:
COMBUSTION CONTROLLER
Document Type and Number:
Japanese Patent JP3023252
Kind Code:
B2
Abstract:
PURPOSE: To embody a combustion controller having high reliability by largely improving control characteristics at the time of abrupt change of a combustion quantity upon change of a load or a target value.
CONSTITUTION: The combustion controller comprises a plurality of speed type temperature regulating means 22-i, a plurality of regulating means 3-i for regulating fuel flow rates of a plurality of burners based on outputs of the means 22-i, first limiting means 7 for selectively outputting a total fuel flow rate obtained from outputs of the plurality of the temperature regulating means and a predetermined limit signal relative to the fuel flow rate and regulating means 10 for regulating the total air flow rate based on the output of the limiting means, and second limiting means 20 for selectively outputting the total fuel flow rate and a predetermined limit signal relative to total air flow rate. Further, the controller comprises removal deciding means 21 for judging out of a limit from input/output difference of the limiting means, discriminating means 25-i for discriminating the output signal of the judging means and the operation signals of the regulating means, and means 23-9 for stopping alteration of the speed type operation signal of the control quantity regulating means in the case of the same code.
