GASEOUS FUEL BURNER - AIR LIQUIDE

Title:

GASEOUS FUEL BURNER

Document Type and Number:

WIPO Patent Application WO/2020/237680

Kind Code:

A1

Abstract:

Disclosed is a gaseous fuel burner, containing a refractory unit (10), a metal piece (20), a fuel-oxidant supply system (11) containing a fuel nozzle and a plurality of fuel-oxidant passages, a first oxidant supply system (12) containing a plurality of first oxidant passages, and a second oxidant supply system (13) containing a plurality of second oxidant passages. An outlet end (1212) of each of the first oxidant passages is provided with a first turning structure (1213), such that the outlet end (1212) of the first oxidant passage faces downward, and a first offset angle is formed between the outlet end and an extension line of a body of the first oxidant passage; and an outlet end (1312) of each of the second oxidant passages is provided with a second turning structure (1313), such that the outlet end (1312) of the second oxidant passage faces upward, and a second offset angle is formed between the outlet end and an extension line of a body of the second oxidant passage. The burner can be used for a kiln with a gaseous fuel, such that combustion effects, such as adjusting the length and direction of a flame, controlling combustion speed, and reducing NOX products can be achieved.
