Boiler Waterwall Tubes and Condenser Tube Leakage in Power

Jun 15, 2009 · Tube failures are a cause of concern in boiler outage, contaminating boiler feed water due to condenser leakage leads to a large amount of damage. Condensers using brackish water for cooling in high pressure boilers will have to be maintained well to avoid any leakage of condenser tubes. Any leakage of condenser cooling water to the condensate leads to low pH levels in boiler water, which …

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

Waste Heat Boiler - an overview | ScienceDirect Topics

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

Water tube boiler test - YouTube

However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced circulation must be introduced.

Steam explosion - Wikipedia

To decrease the likelihood of a devastating explosion, boilers have gone from the "fire-tube" designs, where the heat was added by passing hot gases through tubes in a body of water, to "water-tube" boilers that have the water inside of the tubes and the furnace area is around the tubes. Old "fire-tube" boilers often failed due to poor build
