Title: [Tampa Electric Company IGCC project]. 1996 DOE annual technical report, January--December 1996

Abstract

Tampa Electric Company`s Polk Power Station Unit 1 (PPS-1) Integrated Gasification Combined Cycle (IGCC) demonstration project uses a Texaco pressurized, oxygen-blown, entrained-flow coal gasifier to convert approximately 2,000 tons per day of coal to syngas. The gasification plant is coupled with a combined cycle power block to produce a net 250 MW electrical power output. Coal is slurried in water, combined with 95% pure oxygen from an air separation unit, and sent to the gasifier to produce a high temperature, high pressure, medium-Btu syngas with a heat content of about 250 BTUs/cf (HHV). The syngas then flows through a high temperature heat recovery unit which cools the syngas prior to its entering the cleanup systems. Molten coal ash flows from the bottom of the high temperature heat recovery unit into a water-filled quench chamber where it solidifies into a marketable slag by-product. Approximately 10% of the raw, hot syngas at 900 F is designed to pass through an intermittently moving bed of metal-oxide sorbent which removes sulfur-bearing compounds from the syngas. PPS-1 will be the first unit in the world to demonstrate this advanced metal oxide hot gas desulfurization technology on a commercial unit. The emphasis during 1996 centered aroundmore » start-up activities.« less

  • This quarterly report consists of materials presented at a recent review of the project. The project is an IGCC project being conducted by Tampa Electric Company. The report describes the status of the facility construction, components, operations staff training, and discusses aspects of the project which may impact the final scheduled completion.

  • The third quarter of 1996 has resulted in the completion of over five (5) years of extensive project development, design, construction and start-up of the 250 MW Polk Power Station Unit {number_sign}1 IGCC Project. the combined cycle performance test was completed on June 18, 1996. This test demonstrated that on distillate fuel, the combined cycle achieved a net output of 222,299 KW with a net heat rate of 6,868 BTU/KW. This is about 3.86% and 2.76% better than the guaranteed values of 214,040 KW and 7,063 BTU/KW respectively. During the third quarter of 1996, the combustion turbine was run onmore » syngas two (2) different times for a combined total of about seven hours. Attachment {number_sign}4 shows graphically the transfer from oil to syngas. Emission levels were generally acceptable even though no specific emissions tuning was completed by GE and the emissions monitoring equipment was not yet completely operational.« less

  • The report discusses progress in the following systems: Air separation; Coal-water slurry preparation; Gasifier operation; High temperature syngas cooling; Acid gas removal; Sulfuric acid plant; Slag handling; Fines removal, and process water systems; Brine concentration; Combined cycle performance; and Control systems.

  • Tampa Electric Company continued efforts to complete construction and start-up of the Polk Power Station, Unit {number_sign}1 which will use Integrated Gasification Combined Cycle (IGCC) technology for power generation. From an overall standpoint, the Project continues to track well. The completion of construction system turnovers to Start-up is encouraging. Start-up will accept responsibility of the plant until turnover to operations. The major focus continues to be on the production of first Syngas, scheduled for July 17. All construction, engineering, and start-up activities are in support of Syngas production. Key activities toward this goal include final checkout and startup of remainingmore » gasification systems, completion of punch list items required for first syngas, finalization of operating procedures, preparation of site and area access control plans, site- wide safety training, and other Process Safety management (PSM) requirements.« less

  • This report satisfies the requirements of Cooperative Agreement DE-FC21-91MC27363, novated as of March 5, 1992, to provide an annual update report on the year`s activities associated with Tampa Electric Company`s 250 MW IGCC demonstration project for the year 1993. Tampa Electric Company`s Polk Power Station Unit 1 (PPS-1) Integrated Gasification Combined Cycle (IGCC) demonstration project will use a Texaco pressurized, oxygen-blown, entrained-flow coal gasifier to convert approximately 2,000 tons per day of coal (dry basis) coupled with a combined cycle power block to produce a net 250 MW electrical power output. Approximately 50% of the raw, hot syngas is cooledmore » to 900 F and passed through a moving bed of zinc-based sorbent which removes sulfur containing compounds from the syngas. The remaining portion of the raw, hot syngas is cooled to 400 F for conventional acid gas removal. Sulfur-bearing compounds from both cleanup systems are sent to a conventional sulfuric acid plant to produce a marketable, high-purity sulfuric acid by-product. The cleaned medium-BTU syngas from these processes is routed to the combined cycle power generation system where it is mixed with air and burned in the combustion section of the combustion turbine. Heat is extracted from the expanded exhaust gases in a heat recovery steam generator (HRSG) to produce steam at three pressure levels for use throughout the integrated process. A highly modular, microprocessor-based distributed control system (DCS) is being developed to provide continuous and sequential control for most of the equipment on PPS-1.« less
