Operating Controls - National Board of Boiler and Pressure Vessel …

Steam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

High-pressure steam locomotive - Wikipedia

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High

Boiler Operations That Affect Efficiency (Part 1) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production). However, these two goals often have opposing outcomes.

An introduction to steam generation and distribution

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.
