Estimated Reading Time: 9 minsTypical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.
[PDF]May 04, 2010 · a new boiler, or in one which has been drained and refilled with cold water, as the water warms up, air bubbles form on the tubes. In a very short time pits develop under these bubbles, due to the difference in oxygen concentration under the bubbles and the oxygen concentration in the water surrounding the bubbles. Penetration as high as 50 percent of the …
Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to …
