Latest Developments in Turbocharger Applications in Marine Diesel Engines
(a) Power Turbine Generator
A Power Turbine Generator (PTG) is a system that utilizes the energy of exhaust gases from the main engine to drive an auxiliary turbine, which in turn drives a generator to produce electrical power. The turbine is usually connected downstream of the main turbocharger’s turbine. This setup offers several benefits:
Enhances energy recovery by converting otherwise wasted exhaust gas energy into usable electricity.
