A burner includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.

A heater structure includes a heater body including a burner connected to a valve switch. A pilot fire assembly is covered by a protective cover that has ventilation holes. A switch unit includes an ignition switch, a shut-down switch, an ignition operator, and a shut-down operator. The ignition operator and the shut-down operator are structured to provide a swingable arrangement. The ignition operator may be operated to contact and press the fuel gas valve rod and the ignition switch to open the valve switch for supply fuel gas to the burner and to activate an ignition circuit to cause successive shootings of an ignition pin of the pilot fire assembly to set a flame on the burner. The shut-down operator is operated to contact and press the shut-down switch, so as to cut off a signal of the thermocouple and thus cut off the supply of the fuel gas.

A pilot and burner apparatus is provided for use in firefighting training. The apparatus includes a main fuel conduit and a main fuel valve. The apparatus includes a pilot tube and a pilot fuel conduit configured to deliver fuel from the main fuel conduit to the pilot tube. The apparatus includes main and pilot fuel valves to respectively control a flow of fuel in the main and pilot fuel conduits. In a pilot phase, the valves direct fuel to the pilot tube. An ignition component is configured to ignite fuel in the pilot tube to generate a pilot flame. In a burn phase, the pilot flame generates a controllable flame out of a main burner pipe by igniting fuel exiting the main fuel conduit. The controllable flame can be delivered to a training structure for training purposes.

A combustion apparatus includes a burner, a chamber, and a flame rod. The burner includes a burner port surface in which a plurality of burner ports are open. The chamber includes an attachment surface to which the burner is attached and supplies mixed gas to the plurality of burner ports. The flame rod is attached to a flange portion of a chamber located on an outer circumference side of the burner in plan view. The flame rod includes a core. The core extends diagonally to the attachment surface to pass through the chamber, and is bent toward the burner port surface.

In one aspect a pilot assembly is disclosed for use with a flare having a first flare stack and a second flare stack, each having discharge ends. The pilot assembly comprises a pilot nozzle assembly, a pilot inlet pipe having a pilot fuel inlet, and a pilot ignition system. The pilot nozzle assembly comprises a connecting member, a pilot nozzle inlet, a first pilot nozzle and a second pilot nozzle. The pilot nozzle assembly can direct a quantity of pilot gas received via the pilot inlet pipe out through the first and second pilot nozzles. The first and second pilot nozzles may both be positioned adjacent the discharge end of either one of the first or second flare stacks. Alternatively, the first pilot nozzle may be positioned adjacent the first flare stack's discharge, and the second pilot nozzle may be positioned adjacent the second flare stack's discharge end.

Apparatus for igniting a burner of a barbeque includes a housing, a mesh, an orifice, a pair of conductors and a generator. The housing defines a conduit having an inlet and an outlet spaced apart from the inlet. The mesh occludes the conduit and is positioned adjacent the outlet. The orifice is for receiving combustible gas and communicates with the inlet. The pair of conductors define a gap, the gap being positioned such that the gap is disposed in spaced relation to the mesh and the mesh is disposed intermediate the orifice and the gap. The generator is for producing a spark across the gap.

A spark ignited, gas fueled pilot assembly compromising a bracket and a metal gas tube extending through the bracket and having an outlet end. The gas tube is surrounded by a ceramic jacket which is of such a length as to extend beyond the outlet end of the gas tube by approximately 0.03 such that the gas tube outlet is recessed into the ceramic jacket. The assembly further comprises a pair of ignitor electrodes carried by the bracket and arranged and located relative to the recessed gas supply tube to ignite fuel emanating therefrom.
