This paper is concerned with the evaluation of economic and energy-saving characteristics of a super waste incineration cogeneration plant, which is equipped with gas turbines as topping cycle to overcome the drawback of low power generating efficiency of conventional waste incineration cogeneration plants only with steam turbines. Economic and energy-saving characteristics are evaluated using an optimal planning method, which determines capacities and operational strategies of constituent equipment from their many alternatives so as to minimize the annual total cost. Through a case study, advantages of a super waste incineration cogeneration plant are shown in comparison with a conventional one. A parametric study is also carried out with respect to the amounts of waste collected and energy distributed.
