Indirect vs. Direct: The Heat Transfer Method Does

Most applications employ steam as an indirect source, using either a heat exchanger to transfer heat to a gas carrier or a jacketed vessel or drum to heat a surface. It also is used as a direct heat source to achieve effective drying. The amount of energy that can be carried by steam is related to the pressure at which the steam is delivered.
