Waste Heat Recovery System On Ships | marinersgalaxy

Aug 05, 2016 · Waste Heat Recovery System. Here is the point wise explanation of this: Fuel is burnt in the engine. And the exhaust goes out of it. Although the energy from fuel released in the engine is already used by the engine, but the heat is still there in the exhaust. Now this heat in the exhaust can be used to heat the water and generate steam.

Steam Distribution System - an overview | ScienceDirect Topics

Boilers consist of a number of tubes that carry the water–steam mixture through the furnace for maximum heat transfer. These tubes run between steam-distribution drums at the top of the boiler and water-collecting drums at the bottom of the boiler. Steam flows from the steam drum to the superheater before entering the steam-distribution system.
