(PDF) FAILURE ANALYSIS OF BOILER TUBES OF A THERMAL POWER

The majority of forced outages of these thermal power stations are due to premature failure of vital components such as boiler tubes. Case studies pertaining to the failure analysis of various kinds of boiler tubes such as super heater tubes, reheater tubes, and water wall tubes that have failed involving creep deformation and damage have been

Stress and Integrity Analysis of Steam Superheater Tubes of a

Keywords: superheater, high temperature damage, boiler 1. Introduction Superheater tubes are surfaces for heat exchange, with the object of increasing the steam temperature, after it comes from the boiler drum, to a value higher than saturation. This has two basic purposes: to increase the thermodynamic ef-

Failure analysis of high temperature superheater tube (HTS

failures of superheater tubes occur most frequently. To prevent tube failures, which causes temporary shutdown of the power plant, assessment of the tubes are always conducted according to power plant preventive maintenance practices [7-8]. Boiler tube failures are leading cause of forced outages in fossil-fired boilers.

Failure of Boiler Tubes in Power Plants

failures in high pressure boilers have been attributed to caustic corrosion.11-13 .-On the other hand, solutions of low pH value may be generated in boilers and thus cause acidic corrosion. The pH of all of the boiler water is reduced when contaminants which are _acidic(or become acidic when heated) enter the water circuit or

Failure analysis of the boiler water-wall tube - ScienceDirect

The failure of the boiler water-wall tube is investigated. The fire-facing side of the tube was observed to have experienced significant wall thinning. The iron-to-oxygen ratio of the fire-facing side is smaller than that of the back side. The failure occurred due to oxidation.

Failure Analysis and Prevention of Furnace Water wall Tube

The shutdown due to boiler tube failures causes great loss of power generation and there by result in revenues loss to the power station. Detecting the tube failures and analyzing the causes is an important job to avoid consecutive damages. There is more risk in running boiler with known leaks.

A Review of the Common Causes of Boiler Failure in the Sugar

The failure 'mechanisms' were, more or less, self-selective. Table 1. Mechanisms of pressure part failures. Fatigue accounts for 80% of the failures investigated in fire tube boilers and 28% in water tube boilers. Significantly in the non-sugar, watertube section this rises to 36% but drops to 17% for sugar boilers.
