PCT No. PCT/FI94/00395 Sec. 371 Date May 20, 1996 Sec. 102(e) Date May 20, 1996 PCT Filed Sep. 9, 1994 PCT Pub. No. WO95/11060 PCT Pub. Date Apr. 27, 1995It is possible to more effectively extinguish fires in confined spaces such as engine rooms of ships. General nozzles are disposed above and/or on the sides of the confined space to be protected for general fire extinguishment in the confined space. Spot nozzles may be disposed around specific objects which are susceptible to fire in the confined space, such as engines in an engine room. At least some of the nozzles are low pressure nozzles having wings from which extinguishing water is sprayed at a pressure less than twelve bar, e.g., between 2-12 bar, having water droplets of various size. Due to rotating action of the wings, the water droplets are distributed in the water spray so that the frequency of drops having larger diameters is greater at the periphery of the water spray than in the inner part of the spray, and correspondingly, the frequency of drops having smaller diameters is greater in the inner part of the spray than at the periphery.
