US 2015/0316264 A1 · PILOT BURNER ASSEMBLY AND METHOD OF ASSEMBLING SAME

Abstract

A pilot burner assembly includes a bracket, a thermo-electric device configured to be connected to the bracket, and a unitary pilot guard. The bracket includes a first plate and a second plate spaced from the first plate. Each of the first and second plates have a pilot guard aperture defined therein. The pilot guard has a first end defining a gas inlet configured to receive a gas supply line, and a second end defining a gas outlet. The pilot guard includes an elongate body and a pilot hood disposed at the second end, and is configured be inserted into the pilot guard apertures. The pilot guard further includes a first retention element configured to cooperate with a second retention element on the gas supply line to maintain a connection between the pilot guard and the gas supply line.

Dependent claims

A pilot burner assembly for use with a gas fired appliance, the pilot burner assembly configured to receive gas from a gas supply line, the pilot burner assembly comprising:

a bracket comprising a first plate and a second plate spaced from the first plate, each of the first and second plates having a pilot guard aperture defined therein;
a thermo-electric device configured to be connected to the bracket;
and
a unitary pilot guard having a first end defining a gas inlet and a second end defining a gas outlet, the pilot guard including an elongate body and a pilot hood disposed at the second end, the pilot guard configured to be inserted into the pilot guard apertures and to receive the gas supply line within the gas inlet, the pilot guard further including a first retention element configured to cooperate with a second retention element on the gas supply line to maintain a connection between the pilot guard and the gas supply line.

1 more element

A power generation system for use with a gas fired appliance including a main burner and a gas supply line, the power generation system comprising:

a pilot burner assembly for igniting gas supplied to the main burner, the pilot burner assembly comprising:
a thermo-electric device configured to convert thermal energy into electrical energy, the thermo-electric device having an internal resistance;
and
a pilot guard having a first end defining a gas inlet and a second end defining a gas outlet, the pilot guard including an elongate body and a pilot hood disposed at the second end;
and
a controller configured to receive a signal from the thermo-electric device and control the supply of gas to the main burner based on the signal, the controller powered by electrical energy generated by the thermo-electric device, wherein the internal resistance of the thermo-electric device is matched to a load resistance of the controller to facilitate maximum power transfer between the thermo-electric device and the controller.

3 more elements

A method of assembling a pilot burner assembly for use with a gas fired appliance including a main burner and a gas supply line including an outlet orifice, the pilot burner assembly including a bracket, a thermo-electric device, and a pilot guard, the bracket including a first plate and a second plate, each of the first and second plates having a pilot guard aperture defined therein, the pilot guard having a first end defining a gas inlet and a second end defining a gas outlet, the pilot guard including an elongate body and a pilot hood disposed at the second end, the pilot guard further including a first retention element, and the gas supply line further including a second retention element, the method comprising:

inserting the outlet orifice through at least one of the pilot guard apertures defined in the first plate and the second plate;
and
inserting the pilot guard through each pilot guard aperture such that the first retention element engages the second retention element to maintain a connection between the pilot guard and the gas supply line.
