Chapter 14 - Boiler System Failures | SUEZ

2019-7-31 · Boiler Design Problems. Certain basic design flaws can contribute to tube failures. Problems which occur as a result of a design flaw may be intensified by the boiler water chemistry. The boiler water often contains elements that become corrosive when concentrated far beyond normal values as a result of design problems.

Tube Failures in High Pressure Boilers

There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.

Boiler circulation systems: natural circulation and

For both, steam drum systems as well as once-through steam generators (OTSG) systems, we must have uninterrupted flow of water through the tubes in order for the system to continuously generate steam. For an OTSG system, water travels only one time (single pass) through the boiler tubes before being converted to steam and sent to the steam turbine generator set for producing electricity.

Prediction of risers' tubes temperature in water tube

A dynamic model is developed which enables the prediction of risers' tubes temperature of water tube boilers under various operating conditions. The model is composed of fluid dynamics model representing the fluid flow in the drum-downcomer-riser loop and a dynamic thermal model of the riser's temperature.
