A compound power/cooling cycle with gas turbine for cogeneration of municipal solid waste

In this paper the Authors analyze a Brayton gas turbine cycle modified to be employed for a polyvalent cogeneration. The refrigerator cycle is obtained carrying the turbine expansion until temperature and pressure values lower than the environmental ones. For sake of simplicity, the working fluid is assumed to be dry air, assumed as a mixture of perfect gases, in a closed or half-closed circuit gas turbine limit cycle, i.e. a cycle where the circulating fluid is real, except being inviscid and having thermo-chemical properties calculated as temperature values varying along such a cycle.
