Abstract

An apparatus for discharging condensate in an air cooler of a propelling engine for a ship while preventing the reverse flow of the condensate is provided to prevent destruction of an oil film between a cylinder liner and a piston ring due to the condensate. In a condensate discharging apparatus, the condensate generated in a water mist catcher(20) is firstly discharged to a leakage tank(40) and is secondly discharged to a venting tank(50) connected to the leakage tank by a leakage tank condensate discharge pipe(60) to separate and discharge the air in the condensate. The condensate generated in the air cooler is directly discharged to the venting tank through the air cooler condensate discharge pipe connected to the venting tank. The reverse flow of condensate is prevented by separating the condensate in the water mist catcher from the condensate in the air cooler.

And it is to provide a backflow prevention discharge device of the condensate generated in the air cooler of the marine propulsion engine to prevent corrosion of the cylinder liner due to sulfuric acid generated by the reaction of the condensate and combustion products.

통상 응축수는 엔진의 효율을 높이기 위하여 에어쿨러로 터보차져에 의해 압축된 공기의 밀도를 높일경우 발생된다.Condensate is usually generated when the density of air compressed by a turbocharger is increased by an air cooler in order to increase engine efficiency.
