Abstract
A burner includes a main flange, an oxidant inlet coupled to the main flange, a combustion fuel inlet coupled to the main flange, a nozzle pipe coupled to the main flange, an outer pipe coupled to the main flange, and a diffuser coupled to the nozzle pipe and the outer pipe. The nozzle pipe has an inner volume in fluid communication with the oxidant inlet. The outer pipe is around the nozzle pipe. An annular volume is at least partially defined by the main flange, the nozzle pipe, the outer pipe, and the diffuser. The annular volume is in fluid communication with the combustion fuel inlet. The diffuser may be flat.
Claims25
A burner comprising:
- a main flange;
- an oxidant inlet coupled to the main flange;
- a combustion fuel inlet coupled to the main flange;
- a nozzle pipe coupled to the main flange, the nozzle pipe having an inner volume in fluid communication with the oxidant inlet, the nozzle pipe including:
- a first cylindrical section having a first diameter, the first section proximate the oxidant inlet;
- a second cylindrical section having a second diameter larger than the first diameter;
- and
- a third frustoconical section between the first cylindrical section and the second cylindrical section, the third frustoconical section expanding from the first diameter to the second diameter;
- an outer pipe coupled to the main flange, the outer pipe being around the nozzle pipe;
- a diffuser face coupled to the nozzle pipe and the outer pipe;
- and
- an annular volume located between the nozzle pipe and the outer pipe, wherein the annular volume is defined by the main flange, the nozzle pipe, the outer pipe, and the diffuser face and is in fluid communication with the combustion fuel inlet, the diffuser face being flat and including:
- a first plurality of apertures in fluid communication with the inner volume of the nozzle pipe;
- and
- a second plurality of apertures in fluid communication with the annular volume of the nozzle pipe.
A burner comprising:
- a first plate;
- a second plate, wherein the second plate is distal to the first plate in a direction of a flow of a combustion fuel;
- an oxidant inlet;
- a combustion fuel inlet;
- an inner pipe coupled to the first plate;
- an outer pipe coupled to the first plate, the outer pipe being around the inner pipe;
- and
- an annular volume located between the inner pipe and the outer pipe;
- wherein:
- the annular volume is at least partially defined by the first plate, the inner pipe, the outer pipe, and the second plate;
- the annular volume is in fluid communication with the combustion fuel inlet and is configured to be filled with combustion fuel and to prevent oxidant from entering the annular volume;
- and
- the second plate is flat.
A burner comprising:
- a first plate;
- an oxidant inlet;
- a combustion fuel inlet;
- an inner pipe coupled to the first plate;
- an outer pipe coupled to the first plate, the outer pipe being around the inner pipe, the outer pipe comprising a portion that has a frustoconical shape, a narrower diameter portion and a wider diameter portion;
- and
- an annular volume at least partially defined by at least the first plate, the inner pipe, and the outer pipe;
- wherein the annular volume is located between the inner pipe and the outer pipe and is in fluid communication with the combustion fuel inlet.
