There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater.
For example the high pressure steam boiler in a locomotive may operate at pressures of 200-250 psi (1.38-1.72 MPa) or even higher. Specially constructed very high pressure steam boilers may operate at pressures over 1,500 psi. - Wikipedia 4/14/14 Watch out: You won't find high pressure steam boilers being used for residential building heating
Sep 05, 2016 · "High pressure boiler" means a boiler in which steam or other vapor is generated at a pressure of more than 15 psig, or water is heated to a temperature greater than 250°F and pressure greater than 160 psig for use external to itself. High pressure boilers include at the following: (i) Electric boilers; (ii) Miniature boilers;
The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure. The fuel is burnt in a combustion chamber inside the boiler.

A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars. The output of a railroad steam generator is low pressure, saturated steam that is passed through a system of pipes and conduits throughout the length of the train. Steam generators were developed when diesel locomotives started to replace steam locomotives on passenger trains. In most cases, each passenger locomotive was fitted with a steam generator and a feedwat
