This is a collection of technical papers published by MAN Energy Solutions, Copenhagen/Holeby, Denmark, covering both MAN B&W two-stroke and MAN four-stroke diesel engines. Our technical papers provide information on new engine developments and trends, service experience, important aspects of engine management and maintenance, and emissions requirements compliance and …

· PDF fileToday, this market is dominated by highly efficient twostroke low speed diesel engines which run on low quality fuels and utilise (recover) the exhaust gas heat by means of an ex haust gas boiler/economiser.

A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration.Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from …

The goal is to increase the energy conversion efficiency of both gas turbines and diesel engines, adopted in ship propulsion systems, by recovering part of the thermal energy contained in

· PDF fileCONSIDERATION OF HEAT RECOVERY FOR A DIESEL TWO-STROKE ENGINE Catalin FAITAR2) *, Andra Teodora NEDELCU1), MITSUBISHI TYPE 7UEC85LSII MAIN ENGINE The propulsion of the tanker ship of 300.000 dwt is provided by a Mitsubishi-UE MDE 7UEC85LSII, two-stroke, slow and reversible engine, with a constant overcharging pressure that develops a rated output of 27020 kW at …

· PDF fileIt is possi- ble to generate an electrical output of up to 11% of the main engine power by utilising this exhaust gas energy in a waste heat recovery system compris- ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating.
