Abstract: The present disclosure provides a burner management system (BMS) for an industrial gas appliance and method for controlling a warm-up operation of the industrial gas appliance. The BMS and control method only requires a subset of the burners to be provided with flame detectors. In accordance with one aspect, the method involves lighting a supervised burner by providing a fuel gas flow thereto; continuously detecting a flame at the supervised burner indicating that the supervised burner is lit; incrementally lighting non-supervised burners by providing the fuel gas flow thereto when a non-supervised burner status indicates a safe lighting condition, the non-supervised burner status being determined by: measuring a total fuel gas flowing to the plurality of burners; and determining the number of the non-supervised burners with the fuel gas flowing thereto from the measurement of the total fuel gas and a supervised burner status.

Abstract: A carbon monoxide detection and automatic deactivation system including a fuel burner having a fuel supply conduit coupled thereto. A pilot igniter is situated adjacent to a pilot supply conduit and is adapted to provide a flame in an interior space of the burner upon the actuation thereof. A thermocouple is positioned adjacent to the pilot igniter for producing an electric current upon the detection of heat. Also included is an electromechanical fuel valve comprising a solenoid adapted to allow the supply of fuel to the burner upon the receipt of current via the thermocouple and further preclude said supply upon the lack thereof. Finally, a switch mechanism is electrically coupled between the thermocouple and the solenoid. The switch mechanism has a first orientation for allowing current to pass therebetween with the absence of carbon monoxide and a second orientation for precluding current to pass therebetween with the presence of carbon monoxide.

Abstract: According to this invention there is provided a process and apparatus for the ignition of a pilot burner in an inert atmosphere without substantially contaminating the inert atmosphere. The process includes the steps of providing a controlled amount of combustion air for a predetermined interval of time to the combustor then substantially simultaneously providing a controlled mixture of fuel and air to the pilot burner and to a flame generator. The controlled mixture of fuel and air to the flame generator is then periodically energized to produce a secondary flame. With the secondary flame the controlled mixture of fuel and air to the pilot burner and the combustion air is ignited to produce a pilot burner flame. The pilot burner flame is then used to ignited a mixture of main fuel and combustion air to produce a main burner flame.

Abstract: A cooking range in which a burner below a glass-ceramic plate is ignited with a glow igniter switched off in response to an ionization detector when combustion products are effected so as to prevent excessive heating of the glow igniter.

Abstract: An ignition device for lances, such as lances intended for supplying oxygen gas to metallurgical processes, having a tubular casing intended to be fitted partially onto one end of a lance and the end part of which, located distal from the lance, carries a striker, which includes a pyrotechnical delay, extending into the tubular casing, and a reaction mass which is arranged in the casing and which can be ignited by the striker. The ignition device includes an end stop located in the casing adjacent the reaction mass, the end of the lance being intended to be brought into engagement with the end stop when fitting the device on the lance.

Abstract: A plurality of burners, e.g., steam boiler burners, are provided with air and fuel through separate conduits. A separate air volume regulator is provided for each burner, but only a single fuel volume regulator is provided for all burners. After one burner has been ignited, a signal representative of the air volume associated therewith is supplied to an additional burner, whereby substantially the same volume of air is supplied to the additional burner. To ignite the additional burner, it is then only necessary to double the volume of fuel being supplied, and divide that fuel volume equally among the burners.

Abstract: A control system for multiple burners or heaters in an afterburner section of a metal scrap dryer is provided. The control system provides for cascade and sequential control including selective and sequential ignition as well as selective and sequential deenergization of the burners or heaters.

Abstract: The present invention is an apparatus for preventing gas leakage from gas burning equipment, which comprises an electromagnetic valve which normally closes the gas passage near the gas supplying source, a gas pressure detector for measuring the gas pressure in the gas passage to detect a defect in the piping, at least one gas burning system having electrical circuits for detecting gas leakage other than that caused by defects in the piping, and a control panel for receiving all of the detection results to control the actuation of the electromagnetic valve and to issue an alarm signal, whereby the gas supply is interrupted when nonburning gas escapes from at least one piece of gas burning equipment which is in use and the alarm signal based on a fault or defect in the piping is issued when the gas escapes during a time that all of the gas burning equipment is kept in a non-use condition.
