GAS-DYNAMIC IGNITER Russian patent published in 2008 - IPC F23Q13/00 

FIELD: heating.

SUBSTANCE: invention is referred to thermal engineering and, particularly, to igniting two-component, including two-phase compounds and may be used for development of different heat plants including liquid fuel motors. Igniter includes reverberation chamber having outlet with the installed nozzle for gas supply to heat resonator, resonator, additional mixing chamber, combustion chamber, mounted in series and combined with additional mixing chamber in a housing, supply channels with fuel and oxidiser nozzles. Resonator is put into additional mixing chamber and throttling opening is made between additional mixing chamber and combustion chamber. Cavities in additional mixing chamber and combustion chamber are connected by channels with fuel and oxidiser supply units. The most optimal conditions for fuel ignition and resonator cooling are achieved when diameter of channels connecting fuel supply unit with additional mixing chamber and combustion chamber and diameter of those channels connecting oxidiser supply unit with throttling opening and combustion chambers are realised in ratio d₁/D₁=d₂/D₂=0.15-0.25, where d₁ - diameter of channel connecting fuel supply unit with additional mixing chamber; D₁- diameter of channels connecting fuel supply unit with combustion chamber; d₂ - diameter of channels connecting oxidiser supply unit with throttling opening; D₂ - diameter of channels connecting oxidiser supply unit with combustion chamber.

EFFECT: development of igniter on the basis of on-line gas-dynamic heating with higher reliability factor.
