Abstract
The Tidd PFBC Demonstration Plant is the first utility-scale PFBC demonstration project in the United States. Its objective is to demonstrate that the pressurized fluidized bed combustion (PFBC) combined-cycle technology is a cost effective, reliable, and environmentally acceptable alternative to conventional coal fired electric power generation using flue gas desulfurization. The project will demonstrate PFBC technology on a large scale for use in commercial combined-cycle electric generating plants. The program will demonstrate has turbine survivability and controllability; process performance in removing oxides of sulfur and minimizing the formation of oxides of nitrogen; equipment and system performance and reliability. This paper reviews problems encountered during the first year of unit operation, the modifications made during an outage in the Fall of 1991 to correct these problems, and the post outage operating experiences through July 1992.
