### Boiler (power generation) - Wikiped

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Drawbar horsepower (DBHP) is the horsepower developed by the locomotive at the tender coupler. It is important because this is what moves a train; it’s what pays the bills. It takes energy to move a locomotive, and this energy — which can be significant — reduces the power available from the prime mover that may be used to power a train.
