How to Destroy a Boiler -- Part 1

Typical 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.

What is inside the boiler drum and how it is the steam

All Answers ( 3) The boiler control system has to ensure that the steam drum never overflows with water, or you will get water forced through the steam lines. A very bad thing. To get more energy in the steam, after the steam exits the steam drum, it is sent through another set of tubes, back into the furnace again.

Water Tube Boilers. As the amount of water in the steam drum within the boiler decreases, the amount of heat absorbed by the water decreases, thus heating the steam. Because less water is converted to steam, the existing steam is heated and the pressure inside the vessel increases dramatically due to the offset ratio of water and steam.
