A funnel which forms a part of the engine room , acts as a chimney for the exhaust of engines, boiler steam or engine room gases. It acts as a casing for the uptakes from engine room. It serves the purpose of a normal chimney, and has added modifications for meeting various pollution regulations and safety standards. It clears the exhaust gases off ships deck, and thus keps in check fouling of ships structure or decks. The funnel houses Main engine exhaust, Generator engine exhausts, Boiler exhausts, and also funnel flaps.
The funnel size and shapes will be largely dependent on the volume of exhaust gases produced by the main propulsion engines and auxilliary engines. Funnel volume is also counted with engine room volume, and therefore should be included in all calculations involving engine room volume, for example calculating volume of CO2 needed for a fixed CO2 system.
The funnel also acts as a casing for the Main engine and auxilliary engine exhaust silencers. Catalyric convertors also finds its place inside the engine room funnel.
