摘要： A method is provided for operating a fuel-operated vehicle heater (10) during a start phase of combustion operation. The heater includes a combustion air feed device (26) feeding air and a fuel feed device (22) feeding fuel (B) to a burner area (12) with a combustion chamber (16). An electrically energizable ignition element (32) ignites a fuel/air mixture formed. The method includes energizing the ignition element (32) in a preheating phase prior to the fuel feed, at a time of entry into an ignition phase, detecting electrical resistance of the ignition element (32) and determining a desired resistance based on the electrical resistance of the ignition element (32) detected and operating the ignition element (32) in a resistance-regulating operating mode during the ignition phase such that an actual resistance of the ignition element (32) is in the range of the determined desired resistance of the ignition element (32).

摘要： A new approach for igniting an air-fuel mixture in a turbine or other engine is disclosed. Resonance-enhanced multiphoton ionization (REMPI) is used to generate volume ionization within an air-fuel flow and induce an ignition arc. The output of a relatively low energy single pulsed ultraviolet laser is aimed across an electric field inside a volume of air to create a pre-ionized channel so that a smaller voltage electric field is sufficient to create an electrical arc that follows the pre-ionized channel and will ignite an air-fuel mixture. Because the arc follows the pre-ionized channel, it can be directed to an optimal location inside an ignition volume for igniting the air-fuel mixture. A specific example embodiment is described using a 287.5 nm wavelength pulsed ultraviolet laser to excite ground state oxygen molecules to a specific excited state having a coincident term energy with a specific nitrogen molecule excited state.

摘要： An automatic system and method to provide the ignition and monitoring of a pilot flame for gas burners. The circuit includes a microcontroller that acts on at least one gas valve, a flame igniter, and a flame detector circuits. The valve driver is a switching circuit able to open the valve and keep it open with power saving. The flame detection uses the ionization principle with full use of the rectification property of a flame. Furthermore the flame detection is activated for reduced times to save power. The microcontroller governs the system according to the signals that it receives from points of the circuit. The system provides a circuit realizing advanced power saving techniques to provide also a long term operation on battery powered systems. In addition the automatic control can save gas resources versus traditional thermocouple based systems by applying the intermittent pilot ignition.

摘要： As taught herein, an incinerator system that directly eliminates the undesirable and harmful pollution of any gases vente or exhausted to open air. The system utilizes a fuel injector system that is used to dispense gaseous or atomized fuel of almost any type and inject the fuel into the combustion chamber. The fuel injector system disperses the gaseous or atomized fuel within the combustion chamber. Once the gaseous or atomized fuel is in the combustion chamber, it is then ignited. A controller senses the operational parameters of the incinerator system to control fresh air, ignition and fuel supply to start the system and maintain proper operating temperatures within the incinerator system so as to optimize the combustion efficiency and energy economy of the pollution abatement incinerator system.

摘要： A fuel oil burner utilizing a hot surface ignition with an ignitor that is fully sintered and has essentially no porosity, a voltage phase regulator circuit for applying rectified half-wave AC line voltage, full-wave rectified AC, or either half-wave or full-wave rectified AC line voltage to the ignitor to supply power thereto, and AC line voltage to a blower motor, an AC-to-DC converter, a DC voltage preregulator, and a DC voltage regulator for providing twelve volts DC for operation of a control circuit that has a first time constant circuit for preheating the ignitor and maintaining the ignitor at consistent ignition temperature for a predetermined ignition trial time period and a second time constant circuit for driving second and third motor drive circuits. The third motor drive circuit energizes the start winding of the blower motor and the second motor drive circuit energizes the main winding of the blower motor thus starting the motor and providing fuel to the combustion chamber during a predetermined time concurrent with the ignition trial period. At that time, a third time constant circuit either maintains the fan blower motor in its energized state, if a flame of sufficient magnitude and frequency is detected, or de-energizes the blower motor, if the flame is not detected in less than one second after the ignitor is de-energized.A lock-up circuit is provided such that if no flame is detected, restart is accomplished only by first removing power and then reapplying power to the unit. The unit can be restarted in this manner even if there is a flame in the combustion chamber. Also, a shutdown circuit is provided if the flame detector shorts during burner operation.

摘要： A system is disclosed for monitoring the output of a gas ignition module used for controlling the heating of a cooking device, such as a deep fat fryer, in a pulsed heating mode. The system includes a controller which detects a failure in ignition and alerts the user of the cooking device of such a failure. In a preferred embodiment, an optoisolator is used to monitor the voltage applied to a gas valve. From this determination, the system logically determines when a gas lockout has occurred, and prevents successive ignition attempts, which could result in an unwanted accumulation of gas.

摘要： A spark ignition system for a heater-type ignitor is disclosed. Current through the ignitor is transformed into a voltage which is utilized to operate a timing circuit which, in turn, causes operation of a valve permitting the flow of fuel to a burner. Operation of the valve can occur only after the expiration of a predetermined period of time during which the voltage applied to the ignitor and the current passing therethrough are continuously monitored thus ensuring that the ignitor has reached the ignition temperature of the fuel before the valve is permitted to open.
