摘要

PURPOSE:To effectively remove ash content and soot adhering on blades of a blower or tube of an exhaust gas economizer by adding mixed composition of specified particulate matter, Mg(OH)2 in powder state, and the like through the inlet of a supercharger blower. CONSTITUTION:When the blower blades of a supercharger and the tube fins of an exhaust gas economizer in a diesel engine for marine use are washed, mixed composition of over one sort of fixing substance chosen from crushed coal, rice, walnut shell, granular activated carbon, and granular MgO, and in addition Mg(OH)2 and/or Ca(OH)2 in powder state is prepared. This mixed composition is added from the blower inlet of the supercharger, to remove ash content or soot adhering on the blower blades or tube fins, by making the mixed composition collide with the metal surface of the blower blades of the supercharger or the tube fins of the exhaust gas economizer.
