Jun 24, 2014 · When the steam bubbles condense, the water in the boiler will fall to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. If you have an automatic water feeder, it will open and eventually flood the boiler.

How to Destroy a Boiler -- Part 1
Aug 19, 2020 · Steam boilers are hot and water tight and do not lend themselves to visual inspections. Unfortunately, the consequences of poor pretreatment usually go unnoticed until it's too late. Oxygen pitting that does not show up during inspections is usually only discovered when a boiler tube fails.
Apr 23, 2017 · High water readings in the sight glass of a steam boiler, also referred to by the pros as a flooded steam boiler are most-likely caused by one of the following, of which surging is perhaps the most common problem. Surging in the steam boiler, that in turn cycles the water feed valve when it shouldn't. Surging in a steam boiler, in turn, may be caused by over-firing (burner set too high or wrong burner capacity installed), dirt or debris in the boiler and its water, excessively high steam
Symptoms: Tube experiences metal loss from the OD of the tube. Damage will be oriented on the impact side of the tube. Ultimate failure results from rupture due to increasing strain as tube material erodes away. Causes: Erosion of tube surfaces occurs from impingement on the external surfaces. Firing high ash fuels, such as western U.S. subbituminous coal, may lead to more erosion, slagging and fouling …
Jan 08, 2019 · This video explain What are 3 Types of steam Boiler Tube Failures & Deformities? And How Can Repair?now that we've covered the basic causes of tube failure
As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum. Eventually, sufficient heat is transferred and steam is generated. Colder feedwater replaces the water that rises, which creates the natural circulation. A typical boiler circulation (as …
