High-pressure steam locomotive - Wikipedia

2019-5-10 · A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa). High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction

What is the maximum pressure of high pressure boiler?

It is unclear what you mean by back pressure. Maximum Allowable Working Pressure in a boiler is calculated using the rules for construction of high pressure boilers and construction of heating

Boiler (power generation) - Wikipedia

2019-5-10 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

What is a Maximum Allowable Working Pressure …

Maximum allowable working pressure is used when rating pressure-relief devices that protect vessels. It is also used to rate components such as piping, steam drums, tubes, boilers and any pressure vessels in hydraulic systems. The operating pressure is the pressure that a vessel is subjected to when in service.
