Abstract
A flame-emitting apparatus is provided, whereby a burner has an inlet connected to a fuel source. Fuel burned by the burner provides a flame extending from an outlet of the burner. A flame ignition system detects the presence of the flame during operation of the apparatus and controls supply of fuel to the burner in response to flame detection.
Claims20
An ignition system for flame emitting devices, the system comprising:
- a. a burner;
- b. a temperature sensor positioned proximate to said burner;
- and
- c. a controller in communication with said temperature sensor, the controller configured to analyze output from the sensor, including a current temperature and changes in the temperature, to determine if a flame is present.
1 more element
A flame emitting apparatus comprising:
- a. a burner having an aperture, the burner configured to burn a fuel to emit a flame from the aperture when the burner is ignited;
- b. a temperature sensor having a portion positioned proximate the aperture to detect a temperature of the flame, wherein the portion of the temperature sensor is configured to be positioned within the flame when the burner is ignited;
- and
- c. a control system in communication with the temperature sensor, the control system configured for analyzing output from the temperature sensor to determine if the flame is present.
1 more element
A method for detecting a flame, said method comprising the steps of:
- a. receiving a first reading from a temperature sensor;
- b. waiting a predetermined amount of time;
- c. receiving a second reading from a temperature sensor;
- and
- d. determining whether a difference between the second reading and the first reading is within an acceptable range for passage of the predetermined time.
