锅炉是蒸汽机车上的大型圆柱形水箱。它有一组管子穿过它，将后面的燃烧室与前面的烟箱连接起来。来自燃烧室的热空气和烟雾通过这些管道，加热锅炉内的水，最终使其蒸发成蒸汽。作为加压室中的可压缩气体，蒸汽会在锅炉中积聚，从而增加压力。水的沸点温度取决于锅炉中的压力大小。压力越高，沸点越高。随着锅炉中的蒸汽冷却下来，它会凝结回水。

大多数蒸汽机都有一个安全阀，可以在锅炉超压时释放多余的蒸汽。建议锅炉中的压力与运行发动机所需的压力一样大，不要超过，因为过量会导致燃料浪费。

Maintaining nominal water level in the boiler is critical. Failing to do so can be catastrophic, from damage to cylinders , to boiler explosions . Water is fed to the boiler using an injector and dumped using a blowdown valve .

The boiling point temperature of water depends on the amount of pressure in the boiler. The higher the pressure, the higher the boiling point.
