Exhaust Gas Steam Boiler

2019-5-19 · Exhaust Gas Boilers also known as Exhaust Gas Economizers, with extended heating surface, used for waste heat recovery in motor ships. A diesel engine loses approximately 30% of the energy to the exhaust gases. A turbocharger recover some of it, but there is still heat losses that can be recovered by means of an Exhaust Gas Boiler, EGB.

How do Boilers Work & What is their Use on Ships?

A basic boiler is a machine with the simplest arrangement of the internal parts. The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure.

Boiler Maintenance on Ships - Marine Engineering

The boiler should NOT be depressurised by lifting the safety valves and then filled with cold feed water since the stress induced by too rapid cooling may cause damage. Empty the boiler and close all valves. If the boiler is connected to a second boiler, check that the valves between them are closed.
