Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

Our boilers are normally water tube boilers and most often have four passes: three vertical radiation passes and a convection pass. The first of the radiation passes is integrated into the furnace as a post-combustion chamber. The convection pass, in which the evaporators, superheaters, and economisers are located, may be vertical or horizontal.

superheaters and reheaters is generally pure steam. However, even pure steam reacts with steel to form iron oxide. 3Fe + 4H20 = Fe304 + 4H2 Superheaters and reheaters see especially difficult operating conditions, particularly during start-up, when steam flow has not been fully established. The highest metal temperatures within the boiler are

Superheater and Reheater Temperature Control in Boilers

The superheater temperature control can be done by many ways. Methods like desuperheating by water injection, flue gas flow diverting, burner tilting are few of the commonly adopted systems. In large capacity boilers the injection type desuperheating is adopted for superheater temperature control. Reheater in power boilers can also be technically classified as superheaters, however the type of

The Effects of Carryover in Steam Boiler Systems

Effects of Carryover Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective magnetic layer on steam lines, remove the film formed by filming amine programs, cause erosion-induced corrosion, and result in

Miscellaneous Boiler Types Economisers and Superheaters

Superheaters. Whatever type of boiler is used, steam will leave the water at its surface and pass into the steam space. Steam formed above the water surface in a shell boiler is always saturated and cannot become superheated in the boiler shell, as it is constantly in contact with the water surface.

Why do superheaters work? | Naked Science Forum

A boiler produces saturated steam, meaning its temperature is determined by the boiling point of water at the pressure in the boiler. A superheater takes saturated steam from the boiler and raises its temperature beyond the boiling point to produce superheated steam (or superheated H2O gas if you prefer).

PDF New Microsoft Office PowerPoint Presentation

SUPERHEATERS The function of the superheater in the thermal power plant is to remove the last traces of moisture ( 1 to 2%) from the saturated steam coming out of boiler and to increase its temperature sufficiently above saturation temperature.
