The Boiler Circulatory System: Beyond the Steam-Generating

May 01, 2011 · For a boiler to make steam continuously, it must have water circulating through its tubes. 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.
