Diesel Engine Generator Exhaust System for Submarine
Indigenous development of Diesel Engine Generator Exhaust System for a conventional submarine, which will carry the exhaust on surface and in submerged condition against a known back-pressure (depth). The major challenge being faced is that there are three exhaust valves in each of Port and Starboard sides, depending on operation of the generator in surface or submerged condition respectively. These exhaust valves, if not holding in shut position, result in seawater ingress through them inside the submarine, thereby resulting in flooding. It also leads 1o lesser reliability in submarine operations. A reliable exhaust system, therefore, should be designed and developed by an Indian firm.
