Study of the combined plant for the generator diesel engine; Hatsudenki diesel engine no combined plant no kenkyu

Abstract

It is intended to recover more effectively thermal energy currently discharged from marine vessels into air. This paper describes a diesel engine combined power generation system in which medium-order waste heat energy from a diesel engine for power generation in a marine vessel is recovered and utilized to operate a Rankine cycle system (using the waste gas as the high temperature source and sea water as the low temperature source), thus the thermal energy is recovered as a motive force. Two kinds of fluorocarbons and steam were discussed as a working fluid. Due to fluorocarbons making the whole system ultra-high in pressure, and from a viewpoint of high-temperature thermal stability, the temperature was remained at levels from 100 to 200 degC, and a single-stage expansion cycle was used. With the use of steam, a two-stage reheating cycle was employed, by which the temperature is raised fully up to 300 degC and effective head of fluid was taken largely. Ceramic paint was used as a means to prevent sulfur oxide corrosion when the system is used down to the dew point, and its effectiveness was verified. Motive force recovered by combining the steam two-stage reheating cycle and the ceramic painted heat  More>>

The derived thermal efficiency was about 26%. 2 refs., 24 figs., 2 tabs.}
