Analisis Performasi Kehandalan System Pembangkit Tenaga gas (Turbine Gas) akibat Perubahan Nilai Log Mean Temperature Defference (LMTD) air to air cooler

Abstrak

Turbine Gas generating system is usually need more than five system supporting, fuel system, instrumentasi, air and oil coling system, air admission and compression system, all of them increase performance turbine generally, every system will be primary supporting and always corelated each other. Less efficiency one of above will influence output turbine. Gas turbine Cooling System divide both air cooling and supporting ignation system and oil colling system, its necessary to be empasising of inspection and repair schedule because very urgently to influence out put tubines. LMTD( log mean temperature defference) is one simple methode to appreciate coling system working, value of temperature defference input fluid and output fluid will shown colling system performance, generally turbine gas output will influenced. Key word : LMTD : log mean temperature deferrence Air to air cooler Turbine gas
