PDF Study on Boiler

For example, steam locomotives have fire-tube boilers, where the fire is inside the tube and the water on the outside. These usually take the form of a set of straight tubes passing through the boiler through which hot gas flows. In a cast iron sectional boiler, sometimes called a "pork chop boiler" the water is contained inside cast iron sections.
