DEVELOPMENT OF THE IMPROVED METHODS OF FIGHT AGAINST DISTRIBUTION OF SMOKE ON SHIP WITH SYSTEMS OF JET WATER–GAS EJECTORS

The ways of improving the design of ship openings with the implementation of a method for reducing the intensity of the exit of flue gases through an opening (doors, hatches) of the emergency premise of the ship are considered. The output of flue gases from the emergency premise is proposed to be controlled by the control of gas–air currents with the help of a system of jet water–gas ejectors. Ejectors are equipped with devices for collecting flue gases from the emergency premise of the ship and the collectors of the output of the vapor–gas mixture back to the emergency premise.In case of fire, in the shortest possible time, a high temperature rises in the area of exit from the emergency premise of the ship and a large amount of smoke spreads along the corridors and premises of the ship. These factors require immediate sealing of the emergency premise, which limits the operational access of emergency teams to combat fire.The considered air suppression methods in the ship's aperture and devices for their implementation contribute to screening of heat energy and localization of flue gases in the emergency premise without its sealing to ensure prompt access of emergency teams
