A furnace heating device is provided for the heating a furnace chamber, comprising:

at least one radiant tube, configured to heat the furnace chamber and which can be heated using a burner, which can be operated in a first operating mode with a flame and in a second operating mode with flameless combustion, a burner control device, configured to control on and off states and operating mode setting for the burner of the radiant tube, wherein said burner control device is configured to determine when a temperature (T) of the furnace chamber lies above a critical temperature (T.sub.k), which must at least be present in a combustion chamber for safe operation of flameless combustion, wherein there is a single safety monitor for monitoring the temperature within said furnace chamber and communicating said temperature to said burner control device and wherein said burner control device is configured to send a signal to not send a signal to start said flameless combustion when it is determined that said temperature (T) of the furnace chamber is above the critical temperature and a cooling process or a purging process or a control device switch on procedure has occurred.

A stove for indoor use includes a housing having a bottom wall, a top wall and one or more side walls defining a combustion chamber adapted to retain a fire, and an air supply system for supplying air to the combustion chamber. The air supply system includes a primary air conduit for supplying air to the combustion chamber from below through the bottom wall and a secondary air conduit for supplying air to the combustion chamber from above. A valve is arranged in the primary air conduit or in a branching between the primary and secondary air conduits. The valve is controlled by a bimetal whereby the valve is in a maximum open position when the prevailing temperature is below a first predetermined temperature during start-up of a fire and in a maximum closed position when the prevailing temperature is above a second predetermined temperature after start-up of the fire.

A method of operating a cooktop appliance includes inputting a temperature measurement and a set temperature into a closed-loop control algorithm. When the output of the closed-loop control algorithm is less than a power level threshold, a first control valve to a gas burner of the cooktop appliance is closed.

The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

The present description discloses a combustion type water heater that heats water by burning fuel. The combustion type water heater includes: a burner that generates combustion gas by burning the fuel; a heat exchanger that exchanges heat between the water passing through on an inside of the heat exchanger and the combustion gas flowing on an outside of the heat exchanger, an exhaust pipe that discharges the combustion gas after the heat exchange in the heat exchanger as exhaust gas; an exhaust gas temperature detector that detects a temperature of the exhaust gas flowing in the exhaust pipe as an exhaust gas temperature; a clog degree detector that detects a degree of clog in the exhaust pipe; and a scale buildup determiner that determines whether or not scale has built up inside the heat exchanger based on the exhaust gas temperature and the degree of clog in the exhaust pipe.

Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.

A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool, the radiant burner comprises: a sintered metal fibre sleeve through which combustion materials pass for combustion proximate to an inner combustion surface of the sintered metal fibre sleeve; and an insulating sleeve surrounding the sintered metal to fibre sleeve and through which the combustion materials pass. In this way, a radiant burner is provided which does not crack due to rapid cycling caused by frequent idle steps during which the burner is extinguished. Also, by providing an insulating sleeve, the temperature within the radiant burner and the temperature of an outer surface of the radiant burner remain comparable with existing ceramic burners. This enables the radiant burner to be substituted in place of existing ceramic burners as a line-replaceable unit which does not suffer from cracking during such frequent and short-duration periods of process tool inactivity.

A temperature sensor (1) for gas burner (2) having a thermocouple (11) comprising electric conductors (15) and a connection element (12) to connect to the burner (2) associated with a free end (18) of such thermocouple (11), said connection element (12) being suitable for being inserted inside a seat of the sensor (8) formed inside a wall (4) of the burner (2) and having a first end (26) suitable for being placed at the outer surface (6) of the burner (2), said thermocouple (11) being inserted inside a blind hole (29) of the connection element (12) which opens at a second end (28) of said connection element (12). Said blind hole (29) ends with at least one part (31) convergent towards an end zone (K) of the hole (29), said part (31) getting in contact with the thermocouple (11) inserted inside the connection element, the connection element (12) being made from an iron-chrome-aluminum alloy. An assembly comprising such temperature sensor and a burner is also claimed.

According to an embodiment, a burner system includes a pilot burner disposed in a furnace at a distal position along a main fuel and combustion air flow axis, and one or more main fuel nozzles disposed at a proximal position along the main fuel and combustion air flow axis. The pilot burner is configured to support a pilot flame and the one or more main fuel nozzles are configured to support a main flame in contact with the pilot flame. The pilot burner is disposed to cause the main fuel and combustion air to be ignited by the pilot flame. The pilot burner may support a diffusion pilot flame or may include a premixing apparatus to support a pre-mixed flame.

A gas burner assembly includes a gas burner. A grate with a plurality of fingers is positioned above the gas burner. A sensor finger of the plurality of fingers defines an open downward facing slot at a bottom of the sensor finger. A temperature sensor is mounted to the sensor finger at a first end portion of the slot. A pogo pin terminal block is mounted to the grate at a second end portion of the slot. A wire extends between the temperature sensor and the pogo pin terminal block within the slot.
