Marine Engineering

In addition to providing sufficient air for combustion purposes in the main engine, the auxiliary diesel engines, the fuel-fired boiler, etc., the ventilation system should be designed to remove the radiation/convection heat from the main engine, auxiliary engines, boilers, and other components. A sufficient amount of air should be supplied and exhausted through suitably protected openings arranged in such a way that these openings can be used in all weather conditions, and care should be taken to ensure that no seawater can be drawn into the air intake. Furthermore, the ventilation air inlet should be placed at an appropriate distance from the exhaust gas funnel in order to avoid the suction of exhaust gas into the engine room. Air supply In the case of a low-speed two-stroke diesel engine installed in a spacious engine room, the capacity of the ventilation system should be such that the volume of air is at least 1.5 times the total air consumption of the main engine, auxiliary ...
