Abstract:
A pilot burner assembly comprising:an ignitor comprising an electrically conducting rod extending axially from an ignitor head;an axially extending first tube disposed around the ignitor rod to form a first fluid passageway and having a first tube opening;a first manifold having an eccentric first axial bore therein, a first manifold opening for attachment to a first fluid supply fitting, and a first lateral passageway communicating the first manifold opening with the first axial bore, wherein the first tube is disposed at the first axial bore and the first tube opening cooperates with the first lateral passageway to communicate the first manifold opening with the first fluid passageway;a coupling having an axial coupling bore, wherein the coupling is attached to the first manifold such that the axial coupling bore is aligned with the first axial bore and the ignitor head is received in the coupling such that the ignitor projects through the coupling;an axially extending second tube disposed around the first tube to form a second fluid passageway and having a second tube opening; anda second manifold having an eccentric second axial bore therein, a second manifold opening for attachment to a second fluid supply fitting, and a second lateral passageway communicating the second manifold opening with the second axial bore, wherein the second tube is disposed at the second axial bore, the second tube opening cooperates with the second lateral passageway to communicate the second manifold opening with the second fluid passageway, and the second manifold is attached to the first manifold such that the second axial bore is aligned with the first axial bore and the second manifold opening extends laterally in substantially the same direction as the first manifold opening.
