Selection of Blowdown Systems - Industrial steam

Many high pressure steam boilers require continuous surface blowdown to maintain acceptalbe levels of total disolved solids (TDS) in the boiler. The energy wasted through continuous surface blowdown may be a significant waste of energy, which may make it easy to justify the investment in a heat recovery system.

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-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when
