The moisture in the atmosphere and the combustion of hydrocarbon fuel contribute water to the exhaust such that only about 707. of the water in the exhaust needs to be recovered to satisfy the injection requirement. Recovery of water to produce a dry plant reduces STIG performance only marginally by additional exhaust pressure drop and auxiliary power. "Dry" plants with condensing steam turbines suffer considerable degradation of performance because of the higher condenser pressure and auxiliary power. Due to the lesser penalty for S T I G water recovery than to air cooled condensing ofasteamplant,a STIG maybethemost efficient "Dry" plant. Water recovery from a S T I G is discussed in reference 8. PERFORMANCE The heat rates of combined cycles without supplementary firing and Turbo-STIG systems with similar sophistication are almost identical. Power of the Turbo-STIG can be twice the power of the basic gas turbine without steam injection. Power of an un-refired combined cycle is typically one-and-a-half times the dry gas turbine power. Thus power of the Turbo-STIG is about =37 greater than an unfired combined cycle with the same gas turbine. The efficiency of a combined cycle supplementary-fired to equal the power of the Turbo- S T I G is lower than the STIGefficiency. The efficiency of the Turbo S T I G could be equalled without the Turbo feature by a Combined S T I G with dual steam pressure. The combined STIG with single steam pressure was discussed in an EPRI study ( ,6), but without dual steam pressure its efficiency would not equal the Turbo- S T I G . The Turbo and the combined S T I G s are more efficient than the other S T I G cycles because of the higher steam expansion ratio and the reheat of the steam. As a Turbo - S T I G the expander produces 33-50r more power than normal; the main compressor power is about the same as in the normal engine; and net power can be increased by about 100'1.. Fuel demand is increased by 40% to heat the injected steam from the steam turbine outlet temperature of about 60OF and the slightly hotter than normal compressed air, to combustor outlet temperature. Basic gas turbines need the following modifications to convert them to the Turbo- STIG cycle. 1. A system to extract the compressed air rather than sending the air directly to the combustor. 9.16 1985 1985 1778 1778 1800 1850 111.5 42.3 59.8 528 690 80.54 1754 1754 52.63 64.92 5783 5706 803 --- 6673 3763 6475 5 100.4 38.07 22530 8055 11730 10184 4713 4921 11967 9316 12916 40.71 29.36 32275 53.8 47.37 9412 12381 8961 13987 42.32 27.11 77.82 1.19 58.43 10027 Downloaded from http://asmedigitalcollection.asme.org/GT/proceedings-pdf/GT1989/79160/V004T09A002/4456981/v004t09a002-89-gt-100.pdf by guest on 21 October 2020
