HEAT RECOVERY STEAM GENERATOR (HRSG) – OPERATION AND MAINTENANCE COURSE

Course Description

DURATION

21 hours (Three (3) days)

 

TARGET GROUP

  • Engineering and Procurement engineers
  • Project execution engineers
  • Plant Operation engineers and senior technicians
  • Maintenance Engineers
  • EPCC contracting engineers

 

TARGETED INDUSTRY/INDUSTRIES

Oil & Gas, Petrochemicals, Power Plant, Renewal Energy Plant, Co-Generation Plant and Refineries Plant and other industries that using HRSG for steam generation.

 

CERTIFICATION

This course can be certified under the Continuing Professional Development (CPD) Program by the Board of Engineers, Malaysia (BEM).

 

COURSE OBJECTIVE

This course on HRSG Fundamentals is intended for those that want to know about the HRSG and its use in combined cycle and cogeneration plants. Topics to be covered include types of HRSGs, heat exchangers, boiler circulation systems, components, heat management, controls, water chemistry, emission controls, associated equipment, and fabrication/construction. Key features include heat transfer, surface arrangements; design/operating considerations, and integration with combined cycles and cogeneration equipment. Steam conditions will also be discussed.

 

COURSE OUTCOMES

At the end of the training, the participants will be able to: –

  • Explain heat transfer and flow within HRSG
  • Describe the function of the economizer, evaporator, superheater, reheater, and steam drum components
  • Discuss saturated and superheated steam fundamentals, temperature and superheater controls
  • Identify purpose of drains, vents, and safety valves
  • Outline HRSG controls and protective trips
  • Review HRGS construction
  • Describe the boiler commissioning, operations, trouble-shooting, inspections, repairs and maintenance processes.
