<p>The present invention relates to an anti-freezing structure of a ballast tank using an insulation material, and more specifically, by blocking the introduction of outside cold using an insulation material, freezing of the ballast of a ship sailing in polar regions can be prevented through simple structural changes. Particularly, the present invention can increase the temperature of a ballast tank without comprising a separate heating device, by using the waste heat of combustion gas discharged from an engine combustion chamber of a ship such that the temperature of the ballast tank of a ship sailing in polar regions can be maintained above the freezing point. In addition, the present invention can control the area to which the combustion gas is supplied according to the temperature of the inside of the ballast tank and the height of the sea surface, thereby efficiently using waste heat of the combustion gas. Therefore, reliability and competitiveness for ships and freight fields, and particularly, the ships sailing in polar regions can be improved.</p> |
