A gas cooking assembly comprises: (a) a base part (10) comprising: (a1) a burner body (14) for installation in a cooktop surface (16); (a2) a gas outlet (20) in the burner body (14); and (a3) an ignition source (22) in the burner body (14); and (b) an upper part (12) comprising: (b1) at least one foot (36) for supporting the upper part (12) on the cooktop surface (16); (b2) a grate (26) for supporting a cooking vessel; (b3) an annular flame spreader (28); and (b4) a gas inlet (46) at the bottom side of the flame spreader (28); wherein the upper part (12) is an integral unit that is removable from the base part (10), wherein when the upper part (12) is connected to the base part (10), the gas inlet (46) of the upper part (12) connects to the gas outlet (20) of the base part (10).

The invention relates to a burner as well as to a waste gas treatment device for generating a flame for the combustion of process gas, especially of contaminants, in a combustion chamber, in each case having feed lines for a fuel gas and for an oxidizing agent so that they flow into a pre-mixing chamber, and having an ignition device for igniting the gas mixture contained in the pre-mixing chamber. According to the invention, a sensor for detecting and/or monitoring the flame is provided on the burner, especially at one end of the burner situated opposite from the pre-mixing chamber.

There is disclosed an igniter for a gas turbine engine including: a base; a glow plug heater rod extending from the base along an axis and terminating in a rod end; and a fuel receiver adjacent the heater rod, the fuel receiver including a portion located closest to the heater rod, the rod end protruding axially relative to the axis from the fuel receiver portion located closest to the heater rod.

Sparkless igniters comprising a hot surface igniter assembly and a nozzle that produce a flame plume with diameter substantially similar to the diameter of the fire tube, and flame length less than the length of each leg of the U-shaped fire tube in heater treaters are applicable to both vertical and horizontal heater treaters and improve the durability of fire tubes while reducing igniter fuel consumption by at least 30%.

The present invention relates to a smoke tube boiler including: a mix chamber which includes a mixing space in which combustion gas and air are mixed, a mix chamber body having a flat shape, and a flat plate-shaped burner disposed in a horizontal direction above a combustion chamber; and a heat exchanger which includes an outer shell forming an outer wall of a water tank into and from which a heat medium is introduced and discharged and which accommodates the heat medium, an upper tube plate having an end plate structure that is coupled to the outer shell and configured to form the combustion chamber, a plurality of tubes formed in a flat shape that are configured to allow combustion gas generated in the combustion chamber to flow therein and cause a heat exchange to occur between the combustion gas and the heat medium flowing outside the tubes, turbulators coupled to an inner side of the tube and configured to induce occurrence of a turbulent flow in the flow of the combustion gas, multi-stage barriers disposed between the outer shell and the tube and configured to induce a heat medium flow direction to be alternately changed between a radially inward direction and a radially outward direction, and a lower tube plate having an end plate structure that is configured to support a lower end portion of the tube.

A collapsible camp stove having a cover, a chassis having a fuel burner and a pot support; and the pot support and the chassis and the cover are all pivotally interconnected to one another in a parallelogram structure wherein pivotal opening of the cover relative to the chassis causes the pot support to raise upwardly away from a top surface of the chassis while the pot support continuously remains parallel to the top surface of the chassis.
