대형 터빈계통의 고효율 배압시스템 개발에 관한 연구(II)

A Study on the Development of a High Efficiency Vacuum System for a Large Steam Turbine(II)

The pollution of atmospheric environment becomes serious problem according to the growth of usage of fossil fuel like the coal and the petroleum oil. The demand of clean energy, like the liquefied natural gas(LNG), increases suddenly because it generates few polluting substances when it is burned and it generates relatively less CO₂ gas than the other energy sources. LNG transportation method of our country is marine transportation by ships because the LNG producing place is so far away from our country. All LNG ship use the steam turbine as a main engine, and the vacuum system of steam turbine is a important system for a thermal efficiency of the steam turbine. In this study, a high efficiency vacuum system of steam turbine is developed and accomplished the performance test of this system.
