  • All high pressure boilers commissioned and put into operation go through a stabilization period, during which some teething problems occur, including a few tube failures. Classification of tube failures. Tube failures are classified as in-service failures in boilers. These failures can be grouped under six major causes: Stress rupture; Fatigue

  • The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases. The feed water can be heated to saturation of temperature in the economizer with the help of waste heat.

  • In fire tube boilers the most common cause is internal scale, which prevents sufficient heat transfer and hence adequate cooling. Over-firing, incorrect burner settings and too many on/off cycles are amongst common causes resulting in cracking. In water tube boilers thermal fatigue can occur when there is frequent wetting of a hot surface such

  • What would cause the boiler to overheat after it had turned off? It turns out that when a boiler is running, it requires the pump to be running to move the water around the system, and even when it switches off, lack of movement of the water can allow heat to ‘sit’ in the boiler instead of being carried away.
