Abstract
A controller for an oil fired burner for operating the ignitor initially in an interrupted mode, and instructing the burner to switch to intermittent ignition for a plurality of call-for-heat (“CFH”) cycles if it is determined that the flame quality is insufficient during the flame-proved period. On the last predetermined iteration cycle, a reset condition occurs; setting a counter back to zero, and a retry ignition is performed to operate once again in interrupted ignition mode. When the apparatus is in interrupted ignition mode, if the current CFH cycle ends normally by satisfying the call, the ignition will remain in the interrupted ignition mode.
Claims5
A method for controlling a burner ignition system comprising:
- initially operating said burner in an interrupted ignition mode during a call for heat;
- switching to an intermittent ignition mode for a plurality of call-for-heat cycles if during a flame proven mode, a flame is determined to be insufficient or confirmed lost;
- and
- reverting back to said interrupted ignition mode when a count of said plurality of call-for-heat cycles reaches a predetermined limit.
A burner ignition system comprising:
- an air-oil mixture nozzle;
- electrode tips;
- and a central processing unit implementing a program readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for controlling said burner, said method steps comprising:
- a) initially operating said burner in an interrupted ignition mode during a call for heat;
- b) switching to an intermittent ignition mode for a plurality of call-for-heat cycles if during a flame proven mode, a flame is determined to be insufficient or confirmed lost;
- c) reverting back to said interrupted ignition mode when a count of said plurality of call-for-heat cycles reaches a predetermined limit;
- and
- d) having said ignition system remain in interrupted ignition mode if a current call-for-heat cycle exits due to lost power, lost T-T, or lost limit condition.
