I Learned from That: Opening Drain Valve Leads to

Jul 26, 2010 · The heat in the furnace transfers to the water in these tubes to produce steam. The furnace is at temperatures in the range of 800°C to 1000 °C. The water flowing through the tubes keeps the tube metal temperatures well below the deformation temperatures. If there is no water flow in these tubes, the tubes will overheat and fail.

Water for the Boiler - Spirax Sarco | First for Steam

Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high

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.
