EXHAUST TURBINE POWER GENERATION SYSTEM

PROBLEM TO BE SOLVED: To improve turbine work in an exhaust turbine power generation system comprising exhaust paths of two systems.SOLUTION: An exhaust turbine power generation system comprises: an internal combustion engine in which each cylinder comprises an intake opening part, a first exhaust opening part, and a second exhaust opening part; an exhaust turbine power generator that generates power by rotating a turbine with exhaust gas from the internal combustion engine; an intake pipe connected to the intake opening part; a first exhaust pipe that connects the first exhaust opening part and an inlet part of the turbine; a second exhaust pipe that connects the second exhaust opening part and a turbine downstream exhaust pipe downstream of the turbine without passing through the turbine; and an EGR pipe that connects the second exhaust pipe and the intake pipe without being connected to the first exhaust pipe.SELECTED DRAWING: Figure 1 【課題】２系統の排気経路を有する排気タービン発電システムにおけるタービン仕事を向上させること。【解決手段】排気タービン発電システムは、各気筒が吸気開口部、第１排気開口部及び第２排気開口部を有する内燃機関と、内燃機関からの排気ガスでタービンを回転させることにより発電を行う排気タービン発電機と、吸気開口部につながる吸気管と、第１排気開口部とタービンの入口部との間を接続する第１排気管と、タービンを介さずに、第２排気開口部とタービンの下流のタービン下流排気管との間を接続する第２排気管と、第１排気管に接続されることなく、第２排気管と吸気管との間を接続するＥＧＲ配管と、を備える。【選択図】図１
