Exhaust gas energy recovery is more preferred than the energy contained in the cooling water. This is determined by the higher exhaust gas temperature, from 250 °C to 400 °C, for two-stroke engines and from 400 °C to 500 °C for four-stroke engines. Recovery is accomplished by means of a heat exchanger, called a heat recovery boiler or directly from the exhaust gas by the entrainment of a power turbine that drives an electric generator. Mitsubishi engines waste recovery systems consist of high-quality, highly efficient machinery that significantly increases overall vessel efficiency and it is an effective way to reduce the EEDI (energy efficiency design index ). Very large crude carriers (VLCC) are among the biggest working freight vessels on the planet. With a capacity more than 250,000 dwt, these big vessels are equipped with two-stroke engines of high power.
