HYDROGEN IN THE GAS MICRO BURNER DIFFUSION COMBUSTION STABILIZATION METHOD

摘要

FIELD: power engineering.;SUBSTANCE: invention relates to power engineering. Invention can be used for the metals heat treatment, the jewelry repair and manufacturing, dental prostheses, wires soldering, the joinery decorative charring, the old paint annealing. Hydrogen in the gas micro burner diffusion combustion stabilization method involves the hydrogen micro jet generation in the cylindrical nozzle or Laval nozzle with the supersonic flow rate at the cylindrical nozzle shear exit or in the Laval nozzle critical section. Hydrogen jet is generated in the nozzle at supersonic speed in a cylindrical nozzle with the output diameter of 0.1 to 3 mm, or in the Laval nozzle with a diameter in the critical section of 0.1 to 3 mm, and the hydrogen jet is ignited at a distance from the nozzle exit, where the hydrogen jet with air mixing and burning in the form of detached from the nozzle flame stable turbulent zone is formed, turning into stable turbulent combustion in the entire torch working area.;EFFECT: stabilization of the hydrogen diffusion micro jet combustion at the micro jet outflow supersonic speeds and ensuring the hydrogen stable combustion.;1 cl, 2 dwg
