Aspects of Failure of Condenser tubes and their Remedial

In a fossil power plant coal is burnt in boiler furnace to produce heat which boils the water in the boiler to produce high pressure & high temperature steam. This steam is expanded across a number of turbine blades and the spent steam is condensed in a condenser and pumped back to the steam - …

Erosion-Corrosion Effects on Boiler Tube Metals in a

Erosion-corrosion effects were studied on simulated steam tubes (400–700°F, 204–370°C) oriented either horizontally or vertically in the bed. Results of 50-hr tests showed that the life of heat exchange tubes operating up to 650°F (343°C) in this type of combustor will depend primarily on erosion effects.

Combating hot corrosion of boiler tubes – A study

Dec 01, 2018 · The erosion-corrosion of boiler tubes leads to continuous thinning of the boiler tubes in the working environment; ultimately result into an immediate rupture of the boiler tubes. As per the data, E-C is recognized as the main cause of downtime of the boilers (50–75% of their total arrest time) at power-generating plants [ [74], [75], [76

Finding the Root Cause of Boiler Tube Failures

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
