Resumo
FIELD: heating.
SUBSTANCE: acoustic straight-flow gas burner includes burner body, natural gas supply branch pipe, combustion air supply branch pipe, central gas nozzle and peripheral air nozzle, internal natural gas supply pipeline, acoustic gas-jet emitter consisting of nozzle, resonator and reflector; at that, internal natural gas supply pipeline has variable cross section, and some part of that pipeline, which has an increased cross section, forms housing of acoustic gas-jet emitter, in which its nozzle, resonator and reflector are arranged; at that, nozzle and resonator of acoustic gas-jet emitter, as well as internal natural gas supply pipeline are arranged coaxially; distance from closed end surface of resonator to exit section of central gas nozzle of burner is 3-5 diameters of exit section of central gas nozzle, and cross-section area between outer diameter of resonator and inner diameter of housing of gas-jet acoustic emitter is equal to cross-section area of internal natural gas supply pipeline.
EFFECT: reduction of acoustic vibrations losses at their action on gas burner flame; reduction of dimensions and cost of burner device; shortening of flame length; reduction of fuel unburnt carbon and nitrogen oxide emissions.
