Waste heat recovery systems - GloMEEP

Waste heat recovery systems recover the thermal energy from the exhaust gas and convert it into electrical energy, while the residual heat can further be used for ship services (such as hot water and steam). The system can consist of an exhaust gas boiler (or combined with oil fired boiler), a power turbine and/or a steam turbine with alternator.

Boiler – Fundamentals and Best Practices

Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

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

29/7/2009 · 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.

Waste Heat Boiler Economiser - ThermTech, The waste …

Waste heat boilers are often used to raise steam or hot water by utilising the heat from hot gases exhausted by high energy equipment such as gas engines, turbines, incinerators and regenerating furnaces. A waste heat boiler economiser can be retrofitted onto the exhaust ductwork of the boiler to further cool down exhaust gases and so preheat the boiler feed water.
