Abstract: A wide protection range can be ensured by extending the flying distance of fire-extinguishing agent particles electrified and sprayed from a head. A water-based fire-extinguishing agent is pressurized and supplied to an electrification spray head 10 installed in a protection area A via a pipe, the jetted particles of the fire-extinguishing agent are electrified and sprayed from the electrification spray head 10. The electrification spray head mixes and sprays the fire-extinguishing agent having a comparatively small particle size included in a range from 30 μm to 200 μm by a small-particle jetting nozzle 38a and the fire-extinguishing agent having a comparatively-large particle size of 200 μm to 2000 μm by a large-particle jetting nozzle 38b, thereby carrying the group of the fire-extinguishing-agent particles having the small particle size by the air current caused by spraying the group of the fire-extinguishing-agent particles having the large particle size.

Abstract: An electrostatic atomizing apparatus includes: a liquid nozzle portion for releasing a liquid column into an open space; a liquid conduit portion for introducing pressurized liquid into the liquid nozzle portion; a liquid-side electrode disposed inside the liquid conduit portion for coming into contact with the pressurized liquid; a gas conduit portion made of an insulation material and having a gas nozzle portion disposed around the liquid nozzle portion for converting the liquid column into fine particles to generate an atomized stream by making a gas stream from the gas nozzle portion act at an atomization point of the liquid column released into the open space from the liquid nozzle portion; and a ring-shaped induction electrode disposed around the atomization point located in the open space and having an electrode conductor made of a conductive material and coated with an insulation material.
