Claims
- 1. A heating apparatus which comprises a burner and a combustion chamber, wherein said burner comprises a first portion in which, in use, combustion gases from the or another combustion chamber are mixed with one of (a) fuel, and (b) oxygen or oxygen enriched air, a second generally tubular portion including a line which has a plurality of outlets within the confines of said second portion for introducing fuel radially into said second portion, wherein when said apparatus is in use the mixture leaving said first portion is mixed with the other of (a) said fuel, and (b) said oxygen or oxygen enriched air, wherein said combustion chamber is generally U-shaped, having first and second legs, said second portion of said burner is mounted on the first leg of said "U" in alignment therewith, and said first portion of said burner is mounted between the second leg of said "U" and said second portion of said burner; and means for igniting said mixture leaving said second portion of said burner to produce combustion gases in said first leg of said combustion chamber.
- 2. A heating apparatus as claimed in claim 1, wherein said second portion of said burner is of generally circular cross-section.
- 3. A heating apparatus as claimed in claim 2, wherein said first portion of said burner enters said second portion of said burner substantially tangentially.
- 4. A heating apparatus as claimed in claim 1, wherein said second portion of said burner comprises a fuel supply line which extends along the axis of said second portion and is provided with a plurality of radial outlets, and wherein a substantially circular disc is mounted at the downstream extremity of said fuel supply line.
- 5. A heating apparatus as claimed in claim 1, wherein said combustion chamber is of generally circular cross-section and said first portion of said burner opens tangentially into said second leg of said combustion chamber.
- 6. A heating apparatus as claimed in claim 1, wherein said second leg is provided with a baffle for use during start-up, said baffle having a start-up position in which ambient air can be drawn into the first portion of said burner, and an operating position in which only combustion gases from the combustion chamber can be drawn into said first portion.
- 7. A heating apparatus which comprises a burner and a combustion chamber wherein said burner comprises a first portion in which, in use, combustion gases from the or another combustion chamber are mixed with one of (a) fuel, and (b) oxygen or oxygen enriched air, a second generally tubular portion including a line which has a plurality of outlets within the confines of said second portion for introducing fuel radially into said second portion, wherein said combustion chamber is substantially link shaped having a first leg, a second leg substantially parallel to said first leg, a first end joining one end of said first leg with the adjacent end of said second leg, and a second end connected to the other end of said second leg and opening substantially in line with said first leg, and wherein said first portion and said second portion of said burner are aligned and are disposed between the inlet of said first leg and the outlet of said second end wherein when said apparatus is in use the mixture leaving said first portion is mixed with the other of (a) said fuel, and (b) said oxygen or oxygen enriched air; and means for igniting said mixture leaving said second portion to produce combustion gases in said combustion chamber.
- 8. A heating apparatus including a plurality of combustion chambers and burners, wherein each of said burners comprises a first portion in which, in use, combustion gases from a combustion chamber are mixed with one of (a) fuel, and (b) oxygen or oxygen enriched air, a second generally tubular portion including a line which has a plurality of outlets within the confines of said second portion for introducing fuel radially into said second portion, wherein at least some of said combustion chambers comprise substantially straight tubes, each of said burners is aligned with each said tubes, and means are provided for conveying the combustion gases from the combustion chamber associated with one burner to the first portion of another burner, and wherein when said apparatus is in use the mixture leaving said first portion is mixed with the other of (a) said fuel, and (b) said oxygen or oxygen enriched air; and means for igniting said mixture leaving said second portion to produce combustion gases in said combustion chambers.
