3 1-1. Type of MERS Eco - TG System (Without gas bypass) This is a conventional system which has been applied to the Turbine Generators currently in service. Not so great amount of power generation can be expected. Eco - TG System (With gas bypass) With extracting an exhaust gas partially from main engine to economizer, this system realized more amount of power generation by increasing economizer steam amount and temperature. The power generation amount is 1.5 to 1.8 times more than above system. Suction Air Suction Air Economizer Main Engine Economizer Main Engine Steam Steam S/T S/T Gas Bypass R/G Exhaust Steam (To Condenser) R/G Exhaust Steam (To Condenser) Generator Generator STG System (Super Turbo Generating) The exhaust gas partially extracts from main engine exhaust gas manifold then it drives an Power Turbine, which is connected to steam turbine with SSS Clutch. 2.4 to 2.8 times more power generation than above (1) system Suction Air Turbocharger Turbocharger Turbocharger Economizer Main Engine P/T Steam R/G Gas Bypass SSS Clutch S/T R/G Exhaust Steam (To Condenser) Generator 3
