Unusual Failures Involving Copper Deposition in Boiler

2019-9-22 · Unusual case histories are presented in which boiler tube failure mechanisms involved copper deposition on waterside surfaces. Three case histories on copper-induced liquid metal embrittlement (LME) are reviewed. For copper to cause LME of plain carbon steel boiler tubing, metal temperatures must exceed 871°C (1600°F).

Flush these surfaces completely with water to dissolve, dilute and remove any remaining sulfur compounds. Dry by blowing air through the boiler. All cleaned surfaces should be coated with a good grade of light oil to prevent rust.

2019-12-6 · Coal-fired boiler tubes are generally exposed to high internal pressure and high temperature of steam and flue gas. The common cause of any metallurgical failure of a superheater tube is due to the tube metal temperature higher than that as originally specified 1. Tube metal temperature may increase gradually over many years due to the growing oxide scales inside tube or elevate rapidly

Failure Analysis and Investigation Methods of Reboiler

Failure of boiler and Reboiler tubes is a very common phenomenon in a related plant. The investigation into the causes of tube failure is very important to prevent future tube failures. 1, 10 Identifying correct failure mechanism often helps to perform meaningful life assessment. There can be many reasons for tube failures such as pitting

Analysis of End Crack in Boiler Tube - Scientific.net

Boiler tube failures usually result in frequent forced outages, and ultimately in costly extended outages for major tubing replacement in a plant. There are several failure modes that may occur in a boiler tube, i.e. stress-corrosion cracking, pitting, water-side corrosion, fire-side corrosion, fatigue failure, overheating, dissimilar metal weld fatigue, mechanical fatigue and erosion.
