    Waste Heat Recovery System (WHRS) - MAN Energy Solutions

     · PDF file

    The primary source of waste heat of a main engine is the exhaust gas heat dis-sipation, which accounts for about half of the total waste heat, i.e. about 25% of the total fuel energy. In the standard high-efficiency engine version, the ex-haust gas temperature is relatively low after the turbocharger, and just high enough for producing the necessary steam for the heating purposes of the ship by means of a …

    Waste heat recovery unit - Wikipedia

    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 …

    Technical Papers - MAN Energy Solutions

    Main engine exhaust gas energy is by far the most attractive among the waste heat sources of a ship because of the heat flow and temperature. It is possible 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 comprising both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler …
