An extinguishing head has a double-flow body ( 7 ) including water and gas header, inner gas-nozzle of convergent-divergent profile and inner water-gap of annular cross-section formed by a sleeve ( 4 ) situated coaxially around the inner gas-nozzle. The inner water-gap, formed by the sleeve ( 4 ), has at its outlet a water-nozzle situated at an angle from 0° to 45°, preferable divergently, towards to the inner gas-nozzle axis and the sleeve ( 4 ) makes an inner part of the second gas-nozzle ( 2 ) of convergent-divergent profile and annular cross-section situated coaxially towards to the inner gas-nozzle.
