鍋爐是蒸汽機車上的大型圓筒狀水箱。它的內部由許多稱為「煙管」的管道貫穿兩端，使鍋爐後端的火箱與前端的煙箱互通。來自火箱的熱空氣和煙霧通過煙管，加熱鍋爐內的水，最終使其沸騰轉化為蒸汽。蒸汽為能夠被壓縮的氣體，因此蒸汽會在鍋爐中積聚，從而增加壓力。水的沸點溫度取決於鍋爐內的壓力大小。壓力愈大，沸點愈高。鍋爐中的蒸汽冷卻下來後將會凝結再度轉化為水。

大多數蒸汽機都有一個安全閥，可以在鍋爐超壓時自動釋放過量蒸汽。建議不要產生超過車輛運轉時所需的蒸汽，產生過量蒸汽僅會浪費燃料。

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.
