12 injected at an incremental rate of up to 14,000 lb/hr to yield an additional 2000 hp. CONCLUSIONS Steam injection technology is fast becoming a mature technol ogy with varied and wide application within the utility, cogener ation, and petrochemical industries. This technology has been successfully used for both power augmentation and NOx reduc tion. The steam injection systems have been either part of the original turbine design by the OEMs or have been retrofitted to the existing turbine installations. This technology has not been utilized widely within the gas transmission industry as the majority of gas turbine horsepower involves simple cycle or regenerative cycle installations. Transco's combined cycle plants are good candidates for use of this technol ogy due to the availability of relatively inexpensive, but good quality steam for injection. Power augmentation of an existing gas turbine was cost effec tively implemented using a steam injection system. These older "straight-through combustor" units required a special modifica tion to the combustors. This system was designed, built and tested for adequacy. The normal "around-the-comer combustor" units have been successfully steam injected in the diffuser section of the air compressor. The operating envelop for this unit was developed based on performance tests. It was concluded that the overall combined cycle efficiency is reduced when the unit is injected with steam. This is a surprising conclusion as steam injection is usually thought of as increasing plant efficiency, which it does if steam is raised from "waste" heat. When fuel is burned in the HRSG to produce steam for injection, plant efficiency drops because of the steam's low incremental efficiency. However, for Transco's plant, it is cost effective to generate peaking horsepower using steam injection. At higher steam injection rates, there was an increase in exhaust temperature spreads caused by introduction of steam into different combustion zones. However, there was no degradation of combus tor or hot end performance. Based on empirical correlation of combustor temperatures with the exhaust temperatures, it is pos tulated that the impact on mechanical deterioration of the hot end components will be minimal. The annual hot end inspections were normal. A major overhaul is planned for the summer of 1993 and further inspection and verificationof component life will be made at that time. REFERENCES 1.
