High-pressure steam locomotive - Wikipedia

2020-2-5 · 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 techniques become necessary, but some had boilers

What is Reheater on Boiler? | Technology-Articles.com

High pressure steam turbine output steam, commonly known as cold reheat steam, has lower pressure and temperature of main steam, before entering the turbine. Although the cold reheat pressure is drop significantly, it still has not reached its saturation point. So, if this steam reheated, it will return to superheated steam.

effect of boiler feed water temperature on main steam

IN a OTU, the ratio of firing rate to feedwater flow ( FR/FW) is supposed to be adjusted ( perturbed) so that the main steam outlet temperature achieves the desired setpoint, so the stated issue should never exist. In a drum type boiler, a low feedwater temperature will lead to a higher final steam temperature and a lower steam flowrate.

Residential Steam Boiler Basics

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
