  Development of a waste heat recovery system onboard LNG

  About 48–51% of the total heat energy of the Internal Combustion Engine is thrown back to the atmosphere without any use which considered the main source of waste heat in marine diesel engines. The waste heat recovery system can reclaim and capture the waste heat and improve the overall efficiency of the plant.

  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

  The Engines of the Largest Container Ships in the World

  May 28, 2018 · The crankshafts may set the limits. By MC01, a frequent commenter on WOLF STREET:. Three engine manufacturers have come to dominate the market for the giant low-speed two-stroke diesel engines used in the largest container ships, bulk carriers, and tankers: MAN SE of Germany, Mitsubishi Heavy Industries of Japan, and Wärtsilä of Finland.

  Exhaust Gas Boilers And Economisers working procedure

  Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.

  Entropy | Free Full-Text | Exergy Analysis of Complex Ship

  With multiple primary and secondary energy converters (diesel engines, steam turbines, waste heat recovery (WHR) and oil-fired boilers, etc.) and extensive energy networks (steam, cooling water, exhaust gases, etc.), ships may be considered as complex energy systems. Understanding and optimizing such systems requires advanced holistic energy modeling. This modeling can be done in two ways: The

  A review of the use of organic Rankine cycle power systems

  Aug 01, 2018 · For waste heat recovery applications, the power output of the ORC unit is governed by the amount of heat extracted from the heat source and the thermal efficiency of the Rankine cycle. In the case that the minimum heat source temperature is restricted, the highest power output is achieved for the system with the highest thermal efficiency of

  Jul 29, 2016 · Cylinder lubricating oil for a low-speed main propulsion diesel engine is admitted to each cylinder during the compression stroke. Cylinder lubricating oil, for lubricating the piston rings and the liner, has to be admitted when the piston, piston rings and the liner are in cool condition and the piston is moving upward so that oil can be retained on the piston rings and sprayed by the piston

  How an engine cooling system works | How a Car Works

  A water-cooled engine block and cylinder head have interconnected coolant channels running through them. At the top of the cylinder head all the channels converge to a single outlet. A pump, driven by a pulley and belt from the crankshaft, drives hot coolant out of the engine to the radiator, which is a form of heat exchanger. Unwanted heat is passed from the radiator into the air stream, and
