Tube Failures in High Pressure Boilers - Bright Hub

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 treatment …

Weil McLain Troubleshooting Guide

- Remove and examine the dip tube located in the cold water inlet. Replace if damaged. A broken or melted dip tube will cause the cold water to discharge across the top of the tank, thus short cycling the water heater. Check the operating temperature of the boiler (Non-Warranty) - If possible increase the boiler operating temperature to 200ºF.

Reheaters - an overview | ScienceDirect Topics

The superheater heats steam above the saturation temperature for a particular boiler pressure. Superheater tubes have steam on one side and hot combustion gases on the other. Surface temperatures are higher here than the boiler tubes. The passage of heat from the hot flue gases through the tube wall increases the temperature to about 565°C.
