  • Water Handbook - Boiler System Failures | SUEZ

    Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.Learn More

  • Heat Recovery Steam Generators: Vulnerable to Failure

    Jul 28, 2016 · Flow-Assisted Corrosion (FAC), a chemistry-related failure, causes 40% of all HRSG tube failures. It involves the single (water only) and two-phase (water/steam) variations. FAC originates from the loss of protective metal oxides within the tubes which enables wall loss. Proper boiler water chemistry is critical.Learn More

    Jul 05, 2012 · In high pressure boiler cycles, these temperatures exist in boiler feedwater or "LP" (low pressure) and "IP" (intermediate pressure) sections of a Heat Recovery Steam Generator (HRSG). Aside from the obvious concern of catastrophic failure of feedwater piping, FAC is a significant safety concern.Learn More

  • HRSG Tube Failures: Prediction, Diagnosis and Corrective

    Mar 16, 2003 · Heat recovery steam generators (HRSG) remove heat from exhaust gases, typically from a gas turbine, and convert the energy to steam. The steam may be used for industrial processes or to drive a turbine generator to produce electricity. Failures of boiler tubes and other piping in HRSGs are a growing problem.Learn More

  • What are Boilers and Their Types? - Engineering Choice

    Fire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.Learn More

  • Welcome To Combined Cycle Journal

    Tube samples are taken to charac­terize both hard scales that form in LP boilers and magnetite and copper deposits in HP boilers. Such deposits reduce heat transfer and efficiency and make the HRSG more suscepti­ble to overheating and tube failures. Tubes are sampled only when available NDE methods are not able to meet expectations.Learn More

  • Heat Recovery Boiler - an overview | ScienceDirect Topics

    The steam flow from a heat recovery boiler can usually be increased by the addition of an economizer to preheat the feedwater before it enters the evaporator. The impact of adding an economizer to the evaporator previously analyzed in Fig. 3.1 is shown in Fig. 3.2.The gas temperature leaving the system is reduced substantially and the steam flow is increased approximately 75%.Learn More

  • What Is Steam Boiler?- Definition, Working, and Types

    A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak Learn More

  • Heat Recovery Steam Generator [HRSG] Design & Troubleshooting

    Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure.Learn More
