Some facilities have both kinds, using water-tube boilers with high pressures for process loads while the low pressure fire-tube boilers are used for heating water and space heating. In fact, the two kinds can be combined in the same area.
What is the difference between pressure vessel and boiler
A pressure vessel is a tank designed to hold fluids (gases or liquids or both) at a high pressure without bursting. A boiler is a tank to hold a liquid (often water) so that it can be boiled by a heat source.
