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

In this article, we look at the construction and operation of the marine boilers found on both steam-powered and fuel oil powered ships. The steam generation process is explained and important key phrases are defined. The various uses for steam aboard ship are described, and the difference between the water tube and fire tube basic designs in explained.
