May 2019: Effective HRSG Operations

Posted in Courses

May 15 & 16, 2019 at The Chateaux Deer Valley in Park City, Utah USA

134058019

Course Overview:

This seminar is primarily intended for O&M staff at all levels of experience working in combined cycle power plants, but should also be of interest to engineers and managers involved in new project development. The course gives attendees a comprehensive yet in-depth survey of a broad range of topics relating to the design, operation and maintenance of the HRSG and associated steam cycle systems. This year we’ve added additional material on emissions controls by SCR and CO catalysts as well as additional insights on chemical and fireside cleaning, low load operation and desuperheater design. Also included is a discussion on HRSG Fabrication and Procurement.

Drawing on our field experience working at power plants throughout the world, the objective is to provide attendees with clear instruction on the operator actions and design issues that impact HRSG reliability, efficiency and operating life.

Tetra Engineering has offered this seminar for many years and it is updated annually. Recent seminar sites have included USA, Turkey, UAE and Malaysia. The instructor /seminar leader is David Moelling, P.E., Tetra Engineering’s Chief Engineer. He has presented these seminars for over 15 years. Ms. Early Femiana will discuss the details of HRSG specification, manufacture, shipping and assembly from her 10 years with GE/Alstom for all types of HRSGs.

Combined Cycle Power Plant Fundamentals

Posted in Courses

Overview

Gas Turbine Combined Cycle (GTCC) technology is a leading solution in improving efficiency and reducing emissions. The course provides an introduction to the basic thermodynamic concepts underlying the design and operation of GTCC plants, followed by a description of the major components and their operation.  Participants will complete the course with an understanding of what drives the performance of the integrated plant.  

The one day course is suitable for anyone with a general technical background that is or will be involved in the construction, operation or management of GTCC power plants.

Root Cause Analysis for Boiler & HRSG Failures

Posted in Courses

Overview

This training course is primarily intended for experienced O&M staff working in thermal power and process plants as well engineering and management staff at the corporate level. The objective is to give attendees all the essentials for effective determination of the root cause of failures that can occur in the boiler, HRSG and associated steam balance-of-plant. The principal failure modes are reviewed, with focus on those occurring in the boiler, critical piping and other key components such as pressure vessels and condensers. Major emphasis is placed on analyzing how upstream events in the steam cycle process can lead to failures in downstream components. Several actual failure case histories treated by Tetra Engineering staff at plants around the world are presented, providing attendees with practical application of the presented concepts. 

Course Syllabus

Steam Cycle Components and Failure Modes

A summary of failure modes and mechanisms most frequently observed in various steam cycle components

  • Boiler Tubes and Internal Pressure Parts
  • Boiler Gas Path and Exterior
  • Power Piping (Condensate, Feedwater and Steam)
  • Pressure Vessels

Collecting Evidence and Identifying the Failure Mechanism

The key first step is to define the problem, collect the evidence and then identify the component failure mechanism. It’s important to remember that this is usually not the same as the failure root cause.

  • Defining the Investigation Scope
  • Collecting the Field Evidence: Visual, NDE and Destructive Samples
  • Process Data Collection
  • Overview of Laboratory Analytical Techniques
  • Getting the Most Out of Metallurgy
  • Effective Reporting

Root Cause Analysis Methods

There are several methods or approaches to determining the root cause, these are presented in summary fashion here as background. Despite their differences, all follow a similar overall strategy and aim to achieve the same goal. Whatever the method chosen, it is important to remember that the ultimate objective is to find a solution that prevents further failures.

  • Five Whys
  • Failure Modes and Effects Analysis (FMEA)
  • Pareto Analysis
  • Fault Tree Analysis
  • Current Reality Tree
  • Fishbone Diagram
  • Kepner-Tregoe Method
  • RPR Problem Diagnosis

Sample Case Histories and Discussion

Examples from recent projects performed by Tetra staff are presented, covering failure analyses on a variety of steam cycle pressure part components.

This course is offered in a 2 day format and a condensed 1 day format.

Managing Your Power Piping system

Posted in Courses

Overview

This one (1) day course is primarily intended for experienced O&M staff working in thermal power and process plants, but could also be of interest to corporate engineering and management staff. Incorrectly managed piping systems can cause serious accidents leading to forced shutdowns and injuries to plant personnel.  By managing your power piping in a preventive manner, unwanted loss of production can be avoided, plant safety can be increased and overall maintenance costs can be decreased. By raising the awareness of plant personnel, it is far more likely that potential problems will be detected early, decreasing the risk of forced outages. 

Course Syllabus

The course consists of the following subjects:

  • Understanding Power Piping Design
  • Power Piping Visual Inspection Methods
  • Inspecting and Monitoring Piping Supports
  • Assessing Risks
  • Meeting B31.1 Requirements for Power Piping Inspection and Record Management

Course aim

After course completion the student should be able to:

  • Understand the overall function of pipe supports
  • Understand and apply different inspection methods to piping systems and supports
  • Interpret inspection results
  • Understand the value and basics of inspection result record keeping
