ROOT CAUSE ANALYSIS FOR BOILER & STEAM CYCLE FAILURES

09 - 10 AUGUST 2018, MANILA, PHILIPPINES

About The Course

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 or 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.

Learning Outcomes

  • Gain an overview of the most common damage mechanisms, either on the waterside or fire/gas/air-side, that can affect components in the steam cycle
  • Understand how to define the problem, collect the evidence and then identify the component failure mechanism, which is not the same as the failure root cause.
  • Acquire insight into the various root cause analysis methods, their respective merits and how several were applied in some actual case studies

Who Should Attend

Engineers of all disciplines, managers, technicians, design, maintenance and operations personnel, and other technical individuals who need a comprehensive introduction to practical optimization, operation and design considerations of a major combined cycle power plant.

Course Faculty - James W. Malloy

James is currently Director of European Operations of a leading engineering and inspection consultancy in the power generation sector. Activities are now concentrated on the steam cycle in combined cycle plants, but included projects for coal, oil, diesel and nuclear plants in the past. Areas of specialization are instrumentation and controls (I&C) as well as materials science.

 

CRE S.A., Sophia Antipolis, France, 1987-1991

Lead Engineer, worked on the design and development of real-time systems for controlling diesel generators and turbines. One application involved the development of a complete monitoring system under subcontract to a major European diesel manufacturer, which was subsequently installed on a new black start diesel at a US nuclear plant.

 

Raytheon Company, Development Laboratory, Sudbury, MA. USA , 1983-1987

Engineering and analyses to improve resistance of defense electronic systems to spatial environments and effects of nuclear radiation. This involved designing custom test circuitry and carrying out the tests at both Raytheon and US government facilities.

 

Combustion Engineering Inc., Nuclear Division, Windsor CT. USA, 1980-1982

Worked in the design group responsible for the nuclear fuel reloading (enriched uranium) for the St Lucie 1 and BG&E Calvert Cliffs plants. Used radiation transport programs for simulating the physics of the reactor during a cycle.
