Patent number: 7048537Abstract: An apparatus is provided for controlling a fuel fired heating appliance, the apparatus comprising a first processor for controlling the ignition operation of the furnace and a second processor for controlling the operation of a variable speed blower motor, wherein the first processor sends communication signals to the second processor requesting a desired speed of the blower motor to provide air flow for combustion. The second processor responsively sends a signal to the first processor indicating the receipt of the requested speed for the blower motor. The apparatus further comprises at least one pressure switch, where the first processor senses an opening of the pressure switch and responds by successively sending incrementally higher speed request signals to the second processor until the first processor detects the closing of the at least one pressure switch.Type: GrantFiled: October 12, 2004Date of Patent: May 23, 2006Assignee: Emerson Electric Co.Inventors: Horst E. Jaeschke, Andrew Juengst

Patent number: 7021925Abstract: The invention provides a safety module for connection to a fuel-burning appliance. The safety module connects to the existing circuitry of the appliance and triggers an alarm response when certain predetermined conditions are met. The safety module includes a CO sensor and a processor and can respond not only to acutely high CO levels but also to chronically high CO levels and lack of adherence to service schedules amongst other conditions. The safety module can also be programmed/reset.Type: GrantFiled: May 29, 2002Date of Patent: April 4, 2006Assignee: Invensys Controls LimitedInventor: Charles Perryman

Patent number: 6680614Abstract: A portable spark tester for a gas cooking appliance includes a housing having a non-conductive base assembly, and a plurality of electrical conductive cables each having a first end adapted to be attached to an ignition wire for a respective gas burner of the appliance, and a second end which is secured within the housing at a position spaced from a central electrode. This spaced relationship defines a spark gap across which an electrical charge can jump. In use, the spark tester provides a technician with the ability to correctly identify certain non-functioning components of a spark ignition system of the gas appliance.Type: GrantFiled: December 13, 2001Date of Patent: January 20, 2004Assignee: Maytag CorporationInventors: Prabhat Kumar Tekriwal, Jimmy D.

Patent number: 6652266Abstract: A flame sensor for sensing the presence of a flame in a burner. The signal from the sensor is passed to an amplifier located adjacent to the sensor and amplified without having a sensor signal contaminated with common mode radiation. The selectively amplified signal between 15 and 80 Hz is processed by a microcontroller located remotely from the sensor and amplifier which microcontroller may terminate or continue burner operation. The integrity of the connection circuitry between the amplifier and the microcontroller is also monitored and burner shutdown occurs if there is a fault in such circuitry.Type: GrantFiled: May 26, 2000Date of Patent: November 25, 2003Assignee: International Thermal Investments Ltd.Inventors: Cristian Murgu, Edgar C.

Patent number: 6493081Abstract: A flame-type atomic absorption spectrophotometer forms a flame by igniting a mixture of a fuel gas and a first combustion support gas such as air and then the first combustion support gas is replaced by a second combustion support gas such as nitrous oxide with a faster combustion speed. An optical sensor is disposed near the flame to detect the quantity of light therefrom. A gas flow rate control device independently controls the flow rates of the fuel gas, the first combustion support gas and the second combustion support gas to the flame. A combustion control unit serves to switch the gas to be supplied to the flame from the first combustion support gas to the second combustion support gas, based on how much the quantity of light detected by the optical sensor changes between the time of ignition and after the flow rate of the fuel gas and/or the first combustion support gas is changed.Type: GrantFiled: October 26, 2000Date of Patent: December 10, 2002Assignee: Shimadzu CorporationInventor: Hidehisa Nishigaki

Publication number: 20020099474Abstract: Combustion variables are diagnosed using sensors to measure turbulence in the post-flame zone as well as in the flame envelope of a combustor. Output signals from the sensors are processed and a set of statistical functions are calculated which are correlated with specific combustion variables, such as the concentration of unburned carbon in fly ash. A special sensor mounting box provides reliable long-term operation in harsh combustor environment, without a supply of cooling or protective air flow.Type: ApplicationFiled: August 6, 2001Publication date: July 25, 2002Inventor: Mark J.
