The Waste Heat Boiler operates in a controlled system that converts exhaust heat from the generating sets into steam that is used for hotel services onboard the vessel. Daring the generally successful sea trials of the DDH280 inservice problems developed over one year of operation in varying climatic conditions while being subjected to different input operating parameters.

Jan 01 2013 · Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW and hence reduces boiler fuel requirements. Flue-gases are often rejected to the stack at 30 to 70°C higher than the temperature of the generated steam. Generally efficiency can be increased by ~ 1% for every 22°C reduction in fluegas temperature.

Feb 22 2016 · Waste heat in exiting streams can be removed via heat recovery steam generators (HRSGs) and is most often used on exiting gas streams. Heat recovery from reactions is a viable option when the reactor temperature will be at 150 C or above as this will create steam at high enough pressure to be used in other processes. (Towler and Sinnott 2012) In the case of steam and water

Waste Heat Boiler - an overview | ScienceDirect Topics

In this method the gas is cooled in waste heat boilers and its dust content is removed in cyclones and electrostatic precipitators. The gas at 350 °C is cooled in heat exchangers to about 200 °C using concentrated H 2 SO 4 as a heat exchange medium. It is then scrubbed with the same acid which is now at 150200 °C to convert elemental mercury into a sulfate according to:
