HRSGs for Fast-Starting Combined Cycle Plants

Akber Pasha (Vogt Consulting) brings degrees in Engineering and Business from Osmania University and University of Louisville. He joined Henry Vogt Machine company of Louisville as Design Engineer dealing with the design of Heat Transfer equipment. He has been active in issues dealing with the design and operation of Power Plant equipment, particularly Heat Recovery Steam Generators (HRSGs). The work completed by him and the company for past 50 years has become industry standard for the Design, Operation and Maintenance of HRSGs. During the last 45 years he presented numerous papers in Power conferences throughout the world. He has also developed and presented Workshops on the Design, Manufacturing, Operation, Inspection and maintenance of HRSGs. Presently he is the Consulting Technical Director at Vogt Power International of Louisville, Kentucky. He is a member of various professional organizations such ASME, IGTI, API etc.
