Abstract

The invention provides a gas combustion device for a supersonic blowtorch. The gas combustion device comprises a body combustor (10), a first ignition device (20) and a neck mixer (80). The body combustor (10) comprises a combustion chamber (11) which is provided with a first gas inlet (12) and a first gas outlet (13); the first ignition device (20) is arranged on the body combustor (10); the neck mixer (80) arranged on the body combustor (10) is positioned at the first gas inlet (12) and provided with a first gas passage (81), the first gas passage (81) is communicated with the combustion chamber (11) through the first gas inlet (12), the neck mixer (80) is provided with a first gas nozzle (82) facing the first gas inlet (12), and the first gas nozzle (82) is annually distributed around the first gas passage (81). Damages caused by high-temperature gases generated in the combustion chamber can be reduced by the gas combustion device.

Description

technical field [0001] The invention relates to the technical field of torches, in particular to a gas combustion device for a supersonic torch. Background technique [0002] At present, the supersonic blowtorch in the prior art mainly relies on gaseous fuel contacting with high-temperature gas and spontaneously igniting to generate supersonic flame, and the temperature of high-temperature gas has a great influence on the supersonic flame. High-temperature gas is formed in the gas combustion device. Gaseous fuel, oxygen and air are mixed and ignited in the combustion chamber of the gas combustion device. The specific process is as follows. Oxygen and air are mixed in the mixing chamber independently of the combustion chamber , and then pass into the combustion chamber from the mixing chamber, at the same time, the gaseous fuel also passes into the combustion chamber, start the igniter in the combustion chamber to make the mixture gas in the combustion chamber burn and form h...
