A self-adapting gas turbine firebox with variable geometry includes at least one system with variable opening for automatically adjusting a combustion configuration inside a combustion chamber according to an air temperature, particularly of air from a compressor. The adjustment is performed by a thermosensitive member that controls at least one cross-sectional area of a passage to the combustion chamber, for air which participates in the combustion of fuel or participates in a dilution of gases effective inside the combustion chamber.

A gas range has burner head which have temperature sensing devices as a portion of the burner heads. Upon reaching a predetermined temperature, the temperatures sensing devices reduces gas flow to a bypass amount until temperature drops below to at least the predetermined temperature. Lowering the temperature in a cooking utensil below a common ignition temperature, while still allowing boiling, is an objective of many embodiments.

The disclosure relates to a burner having a container for storing liquid fuel, a fuel inlet for filling liquid fuel into the container, and a fire outlet for fire from burning liquid fuel to leave the burner. The fire outlet may function as fuel inlet or a separate fuel inlet is provided. The burner includes a stopping mechanism and an actuator for controlling the stopping mechanism. The stopping mechanism is displaced by the actuator towards a first position, when the temperature of the actuator is changed from a relatively high temperature to a relatively low temperature. The stopping mechanism is displaced by the actuator towards the second position, when the temperature of the actuator is changed from a relatively low temperature to a relatively high temperature. The disclosure also relates to a method of operating such a burner and a funnel for a burner.

A torch with integral flashback arrestor and thermal shut-off device is provided. In one approach, a torch body includes a passageway of the torch body, and a cartridge assembly disposed within the passageway. The cartridge assembly may include at least one of: a resettable pressure-sensitive device, and a thermal shut-off device, wherein the pressure-sensitive device and the thermal shut-off device are modifiable from a first configuration to a second configuration in response to a pressure or temperature gradient in the torch body, and wherein the second configuration restricts flow through the passageway. The cartridge may further include a check valve disposed along the passageway, for example, within a bore of a bushing, or within a retainer coupled to the torch body at an inlet of the passageway.

A combustor for a gas turbine, including: a combustor chamber; a casing enclosing the combustor chamber and defining an area therebetween for passing compressor discharge air into the combustor chamber for use in combustion; and at least one passive bypass valve for selectively extracting a portion of the compressor discharge air from the area between the combustor chamber and the casing to adjust a temperature in the combustor.
