Abstract

A head assembly for a radiant burner, an inlet assembly and a method are disclosed. The head assembly is for a radiant burner. The head assembly may include a housing defining a plurality of identical housing apertures extending therethrough, an insulator received by the housing and defining a corresponding plurality of identical, complimentarily-located insulator apertures extending therethrough, and at least one inlet assembly configured to be received by one of the identical housing apertures. Each inlet assembly may include a housing portion configured to be received by the one of the identical housing apertures, and an insulator portion configured to fill the complimentarily-located insulator aperture. In this way, a head assembly is provided which has a number of apertures, any of which may receive an inlet assembly. Given that each inlet assembly is configured to be received by any of the apertures, this provides flexibility for the insertion and removal of the assemblies, without needing to completely disassemble the head assembly from the radiant burner. Also, by forming the inlet assembly with a housing portion and insulation portion, the assembly can be located within the head assembly and the insulating portion prevents heat damage.

First claim

1 . A head assembly for a radiant burner, the head assembly comprising:
(a) a housing defining a plurality of identical housing apertures extending there through; (b) an insulator received by the housing and defining a corresponding plurality of identical, complimentarily-located insulator apertures extending there through; and (c) at least one inlet assembly configured to be received by one of the identical housing apertures;
wherein each inlet assembly includes a housing portion configured to be received by one of the identical housing apertures, and
an insulator portion configured to fill the complimentarily-located insulator aperture.

2 . The head assembly of claim 1 , wherein each identical housing aperture comprises a common fixing arrangement operable to receive any one of a plurality of different inlet assemblies, each inlet assembly having a complimentary common fixing arrangement.

3 . The head assembly of claim 1 , wherein each identical housing aperture is distributed across a major face of the housing.

4 . The head assembly of claim 1 , wherein the housing comprises at least one other aperture extending there through and the insulator comprises at least one complimentarily-located insulator aperture extending there through, wherein the other aperture being configured to receive at least one of an inner burner feed assembly, a pilot assembly, a thermocouple assembly and a sight glass assembly.

5 . The head assembly of claim 1 , wherein the housing portion is configured to receive at least one fluid from a corresponding fluid supply and to convey the fluid to a corresponding outlet for supply to a combustion chamber of the radiant burner.

6 . The head assembly of claim 5 , wherein the housing portion is configured to convey the fluid to a plurality of outlets for supply to the combustion chamber of the radiant burner.

7 . The head assembly of claim 5 , wherein the housing portion is configured to receive a plurality of fluids from a corresponding plurality of fluid supplies and to convey the plurality of fluids received to an outlet for supply to the combustion chamber of the radiant burner.

8 . The head assembly of claim 1 , wherein the housing portion further comprises at least one cleaning mechanism operable to clean a corresponding outlet.

9 . The head assembly of claim 1 , wherein the housing defines a gallery operable to distribute fluid from the inner burner feed assembly to a plenum of the radiant burner coupleable to the head assembly.

10 . The head assembly of claim 9 , wherein the housing and the insulator together define the gallery.

11 . The head assembly of claim 9 , wherein the housing portion is configured to extend through the gallery.

12 . The head assembly of claim 1 , wherein each outlet extends at least partially through a corresponding outlet aperture of the insulating portion.

13 . The head assembly of claim 1 , wherein the insulator portion is configured to at least partially surround the outlet.

14 . A head assembly method, comprising:
(a) providing a housing defining a plurality of identical housing apertures extending there through; (b) receiving an insulator by the housing, the insulator defining a corresponding plurality of identical, complimentarily-located insulator apertures extending there through; and (c) receiving at least one inlet assembly with one of the identical housing apertures; wherein each inlet assembly includes a housing portion configured to be received by one of the identical housing apertures and an insulator portion configured to fill the complimentarily-located insulator aperture.

15 . An inlet assembly configured to be receive at least one identical housing apertures of a housing of a head assembly for a radiant burner, the inlet assembly comprising:
(a) a housing portion configured to receive at least one of the identical housing apertures; and (b) an insulator portion configured to fill a complimentarily-located insulator aperture of an insulator received by the housing.
