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

    Jan 21, 2021 · The water tube boilers have tubes with a smaller diameter and also a small steam drum. This will help to produce high temperature and high-pressure steam. The advantage of the water tube boiler is it has less weight than the fire tube boiler. Also, have fast production of the steam. The design of the boiler is very simple and has good efficiency.Learn More

  • Water-tube boiler - Wikipedia

    The water tube boilers work on the principle of convection & radiation. Most modern water tube boiler designs are at very high pressures within a capacity range of 4,500 – 120,000 kg / h. Many water tube boilers used as fuel for oil and/or gas are of "pack" construction. …Learn More

  • Superheated Steam Water Tube Marine Boilers - Bright Hub

    Nov 27, 2009 · References. Ships main engine and auxiliary power generators require a large supply of high pressure superheated steam. This steam is produced by single or multiple water tube oil fired marine boilers. The boilers are all similar in operation but vary by the number of drums they have. These drums are horizontal pressure vessels with domed ends.Learn More
