Locomotive Boilers
Steam locomotives usually do not have condensers so the feedwater is not recycled and water consumption is high. The use of deionized water would be prohibitively expensive so other types of water treatment are used. Chemicals employed typically include sodium carbonate, tannin, phosphate and an anti-foaming agent.
Treatment systems have included:
- Alfloc, developed by British Railways and Imperial Chemical Industries
- Traitement Integral Armand (TIA), developed by Louis Armand
- Porta Treatment, developed by Livio Dante Porta

Famous quotes containing the word locomotive:
“Hereditary property sophisticates the mind, and the unfortunate victims to it ... swathed from their birth, seldom exert the locomotive faculty of body or mind; and, thus viewing every thing through one medium, and that a false one, they are unable to discern in what true merit and happiness consist.”
—Mary Wollstonecraft (1759–1797)
