I know a bit about ships. Here is what causes the bellowing black smoke coming from the funnels. If you encounter a situation where a ship's funnel produces excessive black smoke, you should immediately focus on the three primary machinery systems - Generator, Boiler, and Inert Gas Generator. These systems typically run in port with their exhaust/smoke outlet directed to the ship's funnel. The leading cause of black smoke is an imbalance in the air-fuel ratio that could be due to a shortage of air or fuel not being treated correctly. The black smoke consists of particulates, which are large fuel particles that don't burn completely due to a lack of oxygen.
A ship's funnel integrates all the exhaust trunking from the main engine, generator engine, and boiler inside one enclosure. To identify the source of the black smoke, go to the bridge deck and check which exhaust trunk the black smoke is coming from. Trace the marked trunk from the funnel room and check if it's from the generator or boiler. If it's from the generator, start the standby generator and ensure that the black smoke has subsided before proceeding with troubleshooting. If it's from the boiler, and the cause cannot be detected while running, change all the running machinery to diesel oil and switch off the boiler for troubleshooting.
Also, a thermal and power imbalance could cause black smoke. To identify and correct any imbalances, you must thoroughly check the engine's performance. Remember, timely and assertive action is crucial to resolve this situation.
