EVALUATION OF HIGH TEMPERATURE BOILER TUBES

2013-7-2 · EVALUATION OF HIGH TEMPERATURE BOILER TUBES USING ITERATIVE ANALYTICAL APPROACH ABSTRACT Heat recovery steam generator is used to harvest the exhaust flue gas expelled from gas turbine to generate steam for power generation in steam turbine-generator. The steam is generated via the application of boiler tubes. After several years of operation,

Comparing materials for high-temperature steam piping

2003-1-16 · X20 Material. X20 material was first used in India for high-temperature steam piping around 1970. The next application in India took place nearly two decades later, when the Tata Electric Co. () selected the material for both the main steam and hot reheat lines of its Trombay power station’s 500-MW units.

Tube Temperature Distribution in Water Tube Boiler- A

2017-9-29 · fire tube boilers. The flow of steam and water within a water tube boiler is called circulation. This circulation is critical in preventing tubes from overheating. When tubes are overheated, metal softens, weakens and may eventually rupture. In a simple water tube circuit, bubbles of steam form in the heated tubes or “risers”.

Finding the Root Cause of Boiler Tube Failures

Tube OD surfaces experience thermal fatigue stress cycles which can occur from normal shedding of slag, sootblowing, or from cyclic operation of the boiler. Thermal cycling, in addition to subjecting the material to cyclic stress, can initiate cracking of the less elastic external tube scales and expose the tube base material to repeated corrosion.
