Conceptual design of a gas turbine for PFBC applications
First generation pressurized fluidized bed (PFBC) technology has potential advantages which include: lower capital cost, Unproved environmental performance, shorter lead times, higher efficiency and enhanced fuel flexibility. Coal firing with combustion turbines experiments have been conducted for over forty years. These efforts have evolved to the point where commercial demonstrations are now feasible. The PFBC is one of these technologies. It will be demonstrated as part of the Clean Coal III initiative. PFBC technology is applicable for new installations, replacement of existing equipment as well as repower and retrofit. Included with these options is the opportunity to reduce dependency on fuel oil and well as enhancing environmental performance and increasing efficiency. The turbo-machinery will require design changes to meet the requirements for PFBC application. The major change to the combustion turbine take place in the center section. This section will include provisions to supply compressed air to the PFBC as well as receive vitiated air from the PFBC. These efforts also have the objective of reducing the degree of change from a standard unit. Under a clean coal program a first generation PFBC demonstration win take place at the Des Moines Energy Center. For this demonstration it will be necessary to remove two stages from the 251B12 compressor. This will make the air supplied by the compressor suitable for the PFBC system. The results from this program will be applicable to the DMEC-1 program.
