Steam generators, also known as boilers, are devices that use heat to convert liquid water into steam. They are made up of two main parts: a furnace and a boiler. The furnace burns fuel to create heat, which is then used in the boiler to convert water into steam.  How steam generators work: Fuel is burned inside one or more furnace-tubes that run through a sealed container of water. The heat from the combustion is transferred through the walls of the tubes by thermal conduction. The water is heated and steam is created. Steam generators can use a variety of heat sources,...
