COAL CONSTRUCTION BEGINS ON TECO's POLK IGCC PLANT Tampa Electric Company's (TECO) Integrated Gasification Combined Cycle (IGCC) project in Polk County, Florida was kicked off with an offi cial groundbreaking ceremony the first of Novem ber. The environmental impact assessment for the project was approved in July, and a final financing Department of Energy (DOE) August. agreement with the United States was concluded in According to TECO's D. Pless, this project was originally conceived to respond to the Round III solicitation as part of the Clean Coal Technology Program. The project was 1 of the 13 selected from 49 applicants. Notification of award was received in January 1990. The originally proposed project was a 120-megawatt air-blown fixed-bed gasifier supplying a GE 6EA combus tion turbine/combined cycle powerplant, and in cluded an in-line zinc ferrite Hot Gas Clean-Up system. The general objective of this (HGCU) project was to demonstrate cost competitive in tegrated gasification combined cycle with hot gas clean-up. Due to difficulties encountered with finalizing the power sales agreement with the originally in tended power purchaser, TECO had to search for other purchasers for the unit's output. It then became obvious that a more efficient, more reli able, and more cost-effective arrangement would be necessary. To meet these needs, TECO altered the project's arrangement to include a General Electric 7F(A) combustion turbine (CT)/combined cycle (CC) system to significantly increase the power island efficiency and output. They added a Texaco oxygen-blown entrained-flow gasifier to increase the project's reliability due to the Texaco gasifier's proven track record at Cool Water. They also added an air separation unit and coupled the excess nitrogen to the inlet of the CT to increase system output, reduce NOx emis sions and increase overall plant efficiency. In or 4-7 der to enhance the HGCU performance, the sorbent will be changed to either zinc titanate or a patented sorbent from Phillips Petroleum called Z-Sorb. Finally, to ensure system reliability, TECO opted to install a conventional 100 percent cold gas clean-up system in parallel with a 50 percent HGCU system to insure that the IGCC system would be able to operate regardless of the status of the HGCU system. According to TECO's C. Shelnut, the most novel integration concept in this project is the intended use of the air separation unit. This system provides oxygen to the gasifier in the traditional arrangement, while simultaneously using what is normally excess or wasted nitrogen to increase power output and improve cycle efficiency and also lower NOx formation. To be more commercially and economically ac ceptable, a size of 250 megawatts was selected. The Florida Public Service Commission acknow ledged that with the DOE partial funding, this unit would become a least cost power option. The originally proposed project called for a 50/50 cost shared arrangement between the par ticipant and DOE. DOE would provide $100 million for capital expenses and $20 million for support during the 2-year demonstration period. Because the DOE funds were fixed, the project's support from DOE for the 250-megawatt unit, on a percentage basis, changed from 50 percent to about 20 percent. Project Site The Polk Power site will be built on a Central Florida inland site in southwestern Polk County, Florida. The site, about 1 1 miles south of Mul berry, is a tract previously mined for phosphate and is basically unreclaimed. The selected site is about 4,300 acres. About one-third of it will be used for the generating facilities. As part of this overall plan, the existing mine cuts will be modified and used to form an 850 acre cooling reservoir.
