Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
93 words
Process for combustion of liquid fuel in a burner without a premixing section, wherein, in the interior (14) of the burner, a conical column (5) of liquid fuel, which widens in the direction of flow and does not wet the walls of the interior (14) and which is surrounded by a rotating stream (15) of combustion air which flows tangentially into the burner is formed, ignition of the mixture starts at the burner outlet, and the flame is stabilised in the region of the burner outlet by means of a backflow zone (6).
Claim 2
Dependent Claim
93 words
Process for combustion of liquid fuel in a burner without a premixing section, wherein, in the interior (14) of the burner, a conical column (5) of liquid fuel, which widens in the direction of flow and does not wet the walls of the interior (14) and which is surrounded by a rotating stream (15) of combustion air which flows tangentially into the burner is formed, ignition of the mixture starts at the burner outlet, and the flame is stabilised in the region of the burner outlet by means of a backflow zone (6).
Claim 3
Dependent Claim
121 words
Burner for carrying out the process according to Claim 1, consisting of hollow part-cone bodies making up a complete body, having tangential air inlet slots and feed channels for gaseous and liquid fuels, characterised in that the centre axes (1b, 2b) of the hollow part-cone bodies (1, 2) have a cone angle increasing in the direction of flow and run in the longitudinal direction at a mutual offset, in that a fuel nozzle (3), the fuel injection (4) of which is located in the middle of the connecting line of the mutually offset centre axes (1b, 2b) of the part-cone bodies (1, 2), is placed at the burner head in the conical interior (14) formed by the part-cone bodies (1, 2).
Claim 4
Dependent Claim
30 words
Process according to Claim 1, characterised in that gaseous fuel (13/16) is fed to the combustion air stream (15) before the latter flows into the interior (14) of the burner.
Claim 5
Dependent Claim
27 words
A process according to Claim 1, characterised in that, in near-stoichiometric operation, the excess air in the combustion air stream (15) is replaced by recirculating exhaust gas.
Claim 6
Dependent Claim
21 words
Burner according to Claim 2, characterised in that the part-cone bodies (1, 2) are displaceable towards or away from each other.
Claim 7
Dependent Claim
16 words
Burner according to Claim 2, characterised in that the fuel injection (4) is an air-assisting nozzle.
Claim 8
Dependent Claim
15 words
Burner according to Claim 2, characterised in that the nozzle (3) is a pressure atomiser.
Claim 9
Dependent Claim
24 words
Burner according to Claim 2, characterised in that the part-cone bodies (1, 2) are provided with movable baffles (21a, 21b) on the inflow side.
