Abstract
A method and apparatus for controlling the operation of a plurality of burners of a cupola. The method includes the steps of separately supplying air and fuel to each burner of the cupola, measuring the flow rates of air and fuel supplied to each burner, controlling either the flow rate of air or flow rate of fuel supplied to each burner as a function of a desired heat energy output of the burners and controlling the other of the flow rate supplied to each burner as a function of the measured flow rate of air or fuel supplied to each burner and a preselected ratio of flow rate of air supplied to each burner and of flow rate of fuel supplied to each burner.
Claims27
A method of individually controlling the operation of a plurality of burners of a cupola, the method comprising:
- (a) separately supplying air and fuel to each burner;
- (b) measuring the flow rates of air and fuel supplied to each burner;
- (c) establishing a burner operating set-point as a function of a desired heat energy output of the plurality of burners;
- (d) controlling either the flow rate of air or flow rate of fuel supplied to each burner as a function of the burner operating set-point and the corresponding measured flow rate of air or fuel supplied to each burner;
- and
- (e) controlling the other of the flow rate supplied to each burner as a function of the corresponding measured flow rate of air or fuel supplied to each burner and the product of a preselected ratio of flow rate of fuel to flow rate of air supplied to each burner and differing measured flow rate of air or fuel supplied to each burner.
A control system for controlling the operation of a burner of a cupola comprising:
- (a) means for supplying air and fuel to each burner;
- (b) means for measuring the flow rates of air and fuel supplied to each burner;
- (c) means for regulating the air flow rate supplied to the burner and for regulating the fuel flow rate supplied to the burner;
- (d) at least one controller in communication with said regulating means and said measuring means, said at least one controller controlling either said air flow rate regulating means or said fuel flow rate regulating means as a function of a burner operating set-point and either the corresponding measured flow rate of air or flow rate of fuel supplied to each burner and controlling said other flow rate regulating means as a function of the corresponding measured flow rate of air or fuel supplied to each burner and the product of a preselected ratio of flow rate of fuel to flow rate of air supplied to each burner and differing measured flow rate of air or fuel supplied to each burner.
