Abstract: The present invention provides a system, method and apparatus for controlling a gas-fired heater connected to a fuel source via a fuel source valve that includes one or more power sources, a temperature sensor, a pilotless igniter disposed within the gas-fired heater, a flame sensor disposed within the gas-fired heater and a controller electrically connected to the one or more power sources, the temperature sensor, the pilotless igniter, the flame sensor and the fuel source valve. The controller turns the pilotless igniter on for a first time period and opens the fuel source valve whenever the temperature sensor indicates that a temperature is less than or equal to a low temperature setting. The controller also closes the fuel source valve whenever the temperature sensor indicates that the temperature is greater than or equal to a high temperature setting or the flame sensor indicates that a flame has gone out.

Abstract: A method for controlling the fuel-air ratio of a burner having a blower responsive to a blower drive signal for injecting air into the burner. The method is based at least on the concentration of a gas in an exhaust gas product of a combustion chamber of the burner and includes measuring the gas concentration in the exhaust gas product, deriving a gas concentration signal from the measured gas concentration, determining the fuel-air ratio from the gas concentration signal and the sign of the derivative of the gas concentration signal with respect to the blower drive signal, and controlling the fuel-air ratio by adjusting the air flow rate into the burner. The burner may be, for example, in a Stirling cycle engine.

Abstract: Device for the installation in an air-gas feeding duct, a standard thermocouple to provide both a cold safety function in case of extinction, and a hot safety function, without any additional device, in case of internal combustion. The downstream portion of the bulb side (4) of the thermocouple penetrates into the air-gas duct (2). Its probe tip (3) is immobilized against the inner surface of the diffusion chamber (5) at the centre of the combustion chamber (6). Its connector (16) is secured to its exit point from the duct (2) at a marker-projection (17) by a lock (15). The life span of the thermocouple is considerably increased through permanent cooling by the fresh air-gas mixture of the elements proximate to combustion. In case of internal combustion, the inversion of temperature gradients of the cold and hot junctions of the thermocouple causes the generated electromotive force to fall rapidly. The device is designed for high temperature confinement burners.

Abstract: A means and method for optimizing the efficiency of combustion devices such as furnaces, boilers, ovens, stoves, and the like which automatically tests for and controls the amount of input air utilized by the combustion device to optimize combustion efficiency. The method constantly increases or decreases the amount of input air and monitors the output of the combustion device to see if the change in input air increases or decreases efficiency. If efficiency is increased, the amount of input air is continued to be changed in that direction. If the efficiency is decreased, the change of excess air is reversed. By continuously testing for optimal air fuel ratios, optimal efficiency is reached. The means to accomplish the method include an output monitor, an air input control means, and recording means for recording the output of the combustion device as it presently exists compared to its former reading. A math unit then compares the two readings and depending upon whether output is increased or decreased, utilizes a logic control to signal a switching means which sends a signal to either increase or decrease the input air to the air control means. The means and method can be utilized with combustion devices having variable fuel and air input, or with combustion devices which have a fixed fuel input or which must output at a fixed level.

Abstract: A device for augmenting the control of a forced air furnace includes a heat probe which is located in association with a furnace heat exchanger so as to sense the air temperature of air passing across the heat exchanger. The probe is connected via a buffer to an optical controlled switch. A latch is associated with both the probe and the switch such that in response to a high temperature turn off point the optical coupled switch shuts off the furnace solenoid associated with the furnace and maintains the solenoid in an off position until the probe senses a low temperature turn on point. Upon sensing the low temperature turn on point the solenoid is turned back on and is maintained in the on position by the latch until the high temperature point is again reached.
