The steam generator or steam boiler is an integral component of a steam engine when considered as a prime mover. However, it needs to be treated separately, as to some extent a variety of generator types can be combined with a variety of engine units. A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat.
