The Boiler Circulatory System: Beyond the Steam

Boilers use thermal circulation, in which water is exposed to heat and begins to turn into a water/steam mixture. Since a combination of water and steam is less dense than water, gravity will cause the water to move down and the steam/water mixture to rise. All steam-generating boilers have the same systems described below.
