Steam Boiler: What Is It? How Does It Work? Types Of

A steam boiler is a steam producing heating system; it produces energy by heating water to create steam. A steam boiler burns fuel to heat water. The combination of heat and water produces steam. Steam boilers are defined by their construction, portability, types of tubes, types of fuel, and the pressure they produce.

However, to produce dry steam in an industrial boiler designed to produce saturated steam is rarely possible, and the steam will usually contain droplets of water. In practice, because of turbulence and splashing, as bubbles of steam break through the water surface, the steam space contains a mixture of water droplets and steam.
