Title: High temperature turbine technology program. Phase I. Program and system definition. Topical report: overall plant design description liquid fuel combined cycle electric power plant

Abstract

The combined cycle plant described utilizes an advanced 2600/sup 0/F inlet temperature combustion gas turbine engine and burns a coal-derived liquid fuel. The plant is intended to serve the base and intermediate loads of a utility system. This operation requires that the equipment be capable of cyclic duty and of starting and accelerating to a full load condition in approximately one (1) hour. The plant is comprised of two (2) air-cooled dual liquid fuel combustion gas turbine engines, each rated at a gross output of 122,663 KW. The 1200/sup 0/F exhaust heat of each combustion turbine is recovered in an unfired Heat Recovery Steam Generator (HRSG) generating steam at 1800 psig/1000/sup 0/F/1000/sup 0/F. Intermediate pressure steam is also generated and is mixed with the cold reheat steam prior to the reheater. The tandem compound, double-flow reheat steam turbine operates at throttle conditions of 1800/1000/sup 0/F/1000/sup 0/F TT and a condenser pressure of 2.5 in. HgA. Gross power generated in 72,515 KW per combustion gas turbine unit or 145,030 KW for the plant. The combined heat balance of the plant after allowing 7150 KW for total plant auxiliary power, shows a HHV heat rate of 6966 Btu/KwHr at a net plantmore » output of 383,206 KW. This heat rate translates to an overall efficiency of 49 percent. The alternate plan heat balance, which uses water, steam and air for combustion gas turbine cooling shows the net plant power to be 393,638 KW at a HHV heat rate of 7182.6 Btu/KwHr. On review of the complete overall plant design, the single area requiring technological development is that required to bring a 2600/sup 0/F combustion gas turbine engine burning a coal-derived liquid fuel into commercial use.« less
