Abstract
Gas-steam combined cycle (GSCC) plants are among the best technologies for power production, in particular when operating in combined heat and power (CHP) generation. As far as we know, there is not any efficiency assessment criterion for thermo-economic analysis of GSCC-CHP plants until now. To solve this problem, this paper proposes a novel efficiency assessment criterion through establishing a mathematical model of heat-consume apportionment and then defining a set of thermo-economic performance indexes for the GSCC-CHP plants, based on the basic principle of heat quantity method by synchronically considering some predefined parameters such as energy utilization efficiency of gas turbine units and the unit comprehensive energy utilization efficiency. With the multi-condition analysis of the changed heat load, extraction pressure and water recovery rate, it verifies the feasibility of the efficiency assessment criterion.
