In the summer of 1974, Philadelphia Electric Company placed into service eight regenerative cycle combustion turbines at a site near Philadelphia. It is the first large-scale installation in which the regenerators will be subjected to a large number of starting cycles. The regenerators are of a revised design to function in this service without excessive cracking. The first year’s operating experience is discussed and data is presented on availability, starting reliability, and heat rate. Some of the major problems are reviewed and details on the solutions are presented.
