Boiler Ratings - Spirax Sarco | First for Steam Solutions

Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam at 100°C. This calls for additional enthalpy of saturation of water. As the boiler pressure rises, the saturation temperature is increased, needing even more enthalpy before the feedwater is brought up to

high-pressure steam locomotive - wikipedia

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. In the later years of steam, boiler pressures were typically 200 to 250 psi. High-pressure locomotives can be considered to start at 350 psi, when special construction techniques become necessary, but some had boilers that operated at over 1,500 psi. Delaware & …

Boiler Efficiency and Steam Quality: The Challenge of

This entrainment, while damaging to the steam system, is independent of boiler efficiency. Basically, both high- and low-efficiency boiler operation can produce - or not produce - excessive entrainment. While entrainment cannot be completely prevented, it can be minimized by proper boiler and steam system operation. Case I, On-Off Boiler Feed
