EXHAUST GAS CONTROL DEVICE OF MARINE DIESEL ENGINE USING LOW-QUALITY FUEL SUCH AS HEAVY OIL CONTAINING SULFUR COMPONENT AT HIGH DENSITY

摘要

PROBLEM TO BE SOLVED: To provide an exhaust gas control device of a marine diesel engine which can discharge waste disposal water into the sea even in marine navigation in a special sea area of waste drain water, and in an area other than the special sea area, in the exhaust gas treatment of the marine diesel engine using low-quality fuel such as heavy oil containing, in particular, a sulfur component at high density.SOLUTION: An exhaust gas control device of a marine diesel engine 1 using low-quality fuel such as heavy oil containing a sulfur component at high density comprises a scrubber 3 which hardly removes PMs by using a difference between diffusion rates of a gas and a particulate to an exhaust pipe which continues to an exhaust manifold 2 of the engine.SELECTED DRAWING: Figure 1
