| Summary: | The authors have carried out the design-analytic studies of the efficiency of ternary combined cycle gas turbine including high-capacity gas-turbine system, water vapor circuit and low boiling substance circuit. The analytic expression of the dependence of ternary combined cycle gas turbine efficiency on the principle influencing factors was obtained. It was shown that heat-economy figures of water-steam cycle do not influence the combined cycle gas turbine economy. The authors determined the conditions of increasing the efficiency of ternary combined cycle gas turbine with low boiling substance circuit with respect to waste-heat combined cycle gas turbine. The paper considers the features of using the small deviations method to analyze the efficiency of combined cycle gas turbines. The equation for dependence of the combined cycle gas turbine efficiency on the main influencing factors was established in small deviations; the factors values were calculated. The efficiency of different in structure combined cycle gas turbines with low boiling substance circuit was analyzed by the small deviations method. |
