HYBRID TURBOS FOR POWER GENERATION

摘要

Generally, exhaust gas from the main diesel engine is directed entirely to the turbocharger turbine; the efficiency of the turbocharger is measured by the ratio of the adiabatic heat drop of the turbine to the adiabatic compressive work of the compressor. Due to the increased efficiency of marine diesel engine turbochargers in recent years, sufficient air can be supplied to the engine even when a portion of the exhaust gas is diverted from the engine for purposes such as electrical power generation. Waste heat recovery systems have been developed for practical application, in which about 10% of the exhaust gas is used to drive a power turbine connected to a generator.
