In this Seminar we will learn the principal Boiler Performance Indicators and how those Performance Indicators can help us identify the causes of performance decline.  We will learn ways to accurately measure boiler tube leakage.  In addition we will learn how to establish and use a Boiler Tube Failure Analysis Program to maintain the boiler.  We will lean about the ASME Pressure Vessel Code and its application to boiler tube repairs.

OBJECTIVES:
At the completion of this Seminar the participant will be able to:
  1. Describe circulation in a drum style boiler
  2. Describe the basic thermodynamic process that occurs in the steam generator
  3. Describe the principal performance indicators of boiler operation
  4. Explain how those indicators can indentify causes of deviation in boiler performance
  5. Describe methods  used to identify boiler tube leakage
  6. Provide a basic description of basic boiler tube metallurgy
  7. Describe the areas involved in a boiler inspection
  8. Describe how to develop and use a boiler tube failure analysis program
  9. Describe the ASME Pressure Vessel Code
  10. Explain the ASME Pressure Vessel Code applicable to boiler tube repairs
