Flat flame burner for use in e.g. hop, weeding or defoliation device, has spraying chamber extending in thickness of casing surrounding combustion chamber, and spraying nozzle sparing gas in form of flat jet for combustion of gas

摘要

The burner (1) has a spraying chamber (4) provided between a combustible gas supply connection (2) and a combustible gas spraying nozzle (3), where the chamber extends in a thickness of a casing (6) surrounding a combustion chamber (5). The nozzle sprays the gas in the form of flat jet for the combustion of gas. The casing with an increasing section extends from an open end (7) forming an air inlet (8), close to the nozzle, to an oblong and open end (9) around an opening (10) that canalizes inflamed gas during the combustion of gas.
