What is a steam generator used for?

Steam generators, also known as steam heat sources (commonly referred to as boilers), are mechanical devices that use the heat from fuel or other energy sources to heat water into hot water or steam. The original meaning of "pot" refers to a container for holding water heated over a fire, while "furnace" refers to the place where fuel is burned. Boilers consist of two main parts: the pot and the furnace. Steam generators are important thermal energy conversion devices, primarily used to heat water into steam and hot water.
