ABSTRACT

The energy ofthe exhaust gas from marine diesel engines has long been utilized to operate equipment

such as exhaust gas turbines and exhaust gas boilers to improve fuel efficiency. For large marine diesel

engines, steam output of the exhaust gas boiler is high and is often used for many purposes such as heating

oil, cleaning and maintaining equipment and for life activities ... The paper proposes a new way of taking

advantage of this source of energy. That is to cool the boosted gas for engine by absorption cooling method

usingenergy of exhaust gas boiler.
