Abstract

When a freight ship is in a harbor, a Diesel engine generator is operated to supply electric energy in the ship. Exhaust gas from the Diesel engine causes air pollution in the harbor area. We have tried to develop a heat recovery system with a Stirling engine generator. When the ship is at sea, the Stirling engine generator operates with the exhaust heat of the Diesel engine, and charges batteries in the ship. When the ship is at anchor in the harbor, the charged batteries supply the electric energy into the ship without the operation of the Diesel engine generator. This system is expected that the harbor area is kept clean, because the exhaust gas of the Diesel engine decreases in the area. In this paper, we report structure and performance of an experimental Stirling engine for the system. The engine has target power of 500W, and it can operate using heat source of 400 deg C.
