A control system for a catalytic combustion system on a gas turbine includes a flame preburner, a fuel injector positioned downstream of the preburner and a catalyst positioned downstream of the fuel injector. In such systems, a portion of the fuel combusts within the catalyst itself and the remainder of the fuel combusts in a homogeneous combustion process wave downstream of the catalyst. A sensor in communication with the control system monitors the homogeneous combustion process wave and adjusts the gas temperature at the catalyst inlet to a preferred value based on a predetermined schedule that relates the catalyst inlet gas temperature to operating fundamentals such as adiabatic combustion temperature or the gas turbine's exhaust gas temperature.

The invention relates to an oven or grill burner composed of a flat body delimiting an inner chamber and having fastening protrusions, wherein fastening members are composed of at least a tab made of one piece with a flat body wall or walls. In one embodiment, the burner of the present invention includes mountings for fastening a thermocouple and / or igniter and / or a venturi tube that supplies an air and gas mixture, all included as integral members of the burner. The burner of the present invention is shaped such to increase the even distribution of the air / gas mixture to outlet holes and further includes such constructive characteristics that provide for a reduction in the thickness of the metal sheet used for making the burner without compromising burner strength.

The invention provides a gas burner (10) with a high power burner unit and a low power burner unit.

A method and apparatus is provided for initiating and stabilizing fuel combustion in applications such as gas turbine electrical power generating engines and jet turbine engines where it is desired to burn lean fuel / air mixtures which produce lower amounts of NOx. A laser induced spark is propagated at a distance from the fuel nozzle with the laser ignitor being remotely located from the high temperature environment of the combustion chamber. A laser initiating spark generated by focusing high peak power laser light to a sufficiently tight laser spot within the fuel to cause the ionization of air and fuel into a plasma is unobtrusive to the flow dynamics of the combustion chamber of a fuel injector, thereby facilitating whatever advantage can be taken of flow dynamics in the design of the fuel injector.

A method for monitoring a flame in a combustion chamber comprising a wall with an outer side is provided, wherein the radiation which is emitted from a part of the outer side of the wall is optically detected by a sensor. Furthermore, a burner is provided, especially for use in a gas turbine. The burner comprises a wall section with an inner side, which shows towards a combustion zone, and an outer side. The burner further comprises a sensor for optically detecting the radiation emitted from the outer side of said wall section.

The invention relates to a gas turbine combustor, being able to suppress excessive temperature rise of a structure of the gas turbine combustor and ensure the reliability of the gas turbine combustor. In a gas turbine combustor (3) of the present invention, an air hole plate 20 includes a center air hole group 51 configured from a plurality of air holes (51A) and (51 B) and a plurality of outer circumferential air hole groups (52) configured from a plurality of air holes (52A, 52B), and (52C) and formed to surround the center air hole group (51). The gas turbine combustor (3) includes a hole part (601) and a temperature sensor (401) provided on the air hole plate (20) to be located in a region surrounded by two outer circumferential air hole groups (52) adjacent to each other and the center air hole group (51), a supply source (220) of coolant, a cooling pipeline (205) that connects the hole part (601) and the supply source (220), valves (67, 68) provided in the cooling pipeline (205), and a control system (500) that drives the valves (67, 68) on the basis of a measured value of the temperature sensor (401).

A combustor nozzle includes a center body and a shroud circumferentially surrounding at least a portion of the center body to define a passage between the center body and the shroud. A guide between the center body and the shroud can pivot with respect to the center body. A method for supplying fuel to a combustor includes flowing a working fluid through a nozzle at a mass flow rate and flowing a fuel through the nozzle. The method further includes sensing a flame holding event inside the nozzle and pivoting a guide inside the nozzle to increase the mass flow rate of the working fluid flowing through the nozzle.

A burner control valve with speed control includes a speed control assembly for metering loading pressure into a loading pressure chamber to prevent pilot light blow out and / or backfire in a downstream burner.

A gas stove having a temperature sensing function comprises a stove body, a temperature sensor and a gas controller. The stove body includes a burner assembly for heating a pot. The temperature sensor includes a thermopile sensor and a signal processor. The thermopile sensor senses infrared rays radiating from the pot and outputs a sensing signal. The signal processor is electrically connected with the thermopile sensor to process the sensing signal and outputs a control signal. The gas controller is electrically connected with the signal processor and adjusts a gas flow supplied to the burner assembly according to the control signal. The aforementioned gas stove senses the temperature of the pot with a non-contact manner.

A such as a furnace or boiler includes a perforated reaction holder configured to hold a combustion reaction that produces very low oxides of nitrogen (NOx).

A fuel supply system for a gas burner assembly includes a fuel supply, a forced air supply, and an injection assembly positioned proximate the gas burner assembly for providing a flow of combustion air and fuel through an inlet into a fuel chamber. A pressure controlled valve is operably coupled with the fuel supply and the forced air supply, the pressure controlled valve being configured for stopping the flow of fuel when a pressure of the flow of combustion air drops below a predetermined pressure, potentially indicating a malfunction or failure of the forced air supply.
