<p>A method and apparatus for maintaining and reinforcing, in an accumulation tank, a stratified condition of fluid caused by the fluid in the tank, when flow of the fluid is caused by heating the same, causes a portion of the fluid to be heated. The heated fluid is permitted to ascend through a liquid column separated from the fluid in the tank; and is conducted back into the tank at a fluid layer that has substantially the same temperature as the heated fluid.</p> |
