A venturi nozzle for a gas combustor includes an orificed gas nozzle, a venturi tube and one or more support members. The orificed gas nozzle has a longitudinal axis, an inlet and an outlet. The venturi tube is aligned with the longitudinal axis and has an entrance proximate to the outlet of the orificed gas nozzle and an exit. The support member(s) are attached between the orificed gas nozzle and the venturi tube to create a gap between the venturi tube and the orificed gas nozzle. In some embodiments, two or more venturi nozzles can be combined together in various configurations into a nozzle assembly or multi-nozzle gas combustor and attached, mounted or disposed within a stack, chimney or vented enclosure. The wall(s) of the stack, chimney or vented enclosure may include one or more openings, cut outs or vents to provide primary and secondary air to the venturi nozzles.

A combustion chamber for a gas turbine is provided. The combustion chamber has a pilot burner device, a fuel injector and an ignitor unit. The pilot burner device has a pilot body with a pilot surface which is facing an inner volume of the combustion chamber. The fuel injector has a fuel outlet for injecting a fuel into the inner volume. The ignitor unit is adapted for igniting the fuel inside the inner volume, wherein the ignitor unit is arranged at the pilot surface such that fuel which passes the ignitor unit is ignitable. The pilot body includes a recess, wherein the fuel outlet is arranged within the recess.

A gas control valve featuring magnetic control and a gas ignition system having the same are disclosed. The gas control valve includes a main body and a magnetic control assembly. The main body has a valve base and a control lever. The control lever is movably connected to the valve base. The magnetic control assembly has a magnetic member and a magnetic control switch. The magnetic member is installed in one of the valve base and the control lever, while the magnetic control switch is installed in the other of the valve base and the control lever. When the control lever moves to an ignition position, the magnetic control switch is affected by the magnetic member and forms a closed circuit. The magnetic control assembly is incorporated in the gas control valve in a modularized manner, and can be easily maintained and repaired.
