FIELD: process engineering.
SUBSTANCE: invention relates to fluid spraying and can be used in ship engine room fire extinguishing systems. Sprayer comprises truncated-cone case 1 with inlet pipe 2 communicated with atomisers arranged regularly over side surface of said cone. Every atomiser 3 has cylindrical inlet channel 4, swirling chamber 5, conical discharge channel 6, its diameter exceeding that of channel 4, and discharge nozzle 7. Said channel 4 incorporates swirler 8 with its discharge channel 8 having rectangular cross-section and being located in the plane perpendicular to atomiser axis 3 and in tangent to swirling chamber wall 5.
EFFECT: fluid fine spray at low feed pressure making at least 0,6 MPa.
