A suction cooling and regenerative gas turbine plant is proposed in this paper. The power plant is composed of a single-stage absorption-type refrigerator (with an air cooler for suction cooling) and a regenerative gas turbine. Better performance is obtained with the decrease of air inlet temperature, or the increase of cycle temperature ratio and with careful balance of exhaust waste heat between the regenerator and the evaporator of the refrigerator. The results of thermodynamic study indicate that the compound power plant is of significant efficiency and output power, in addition, it is not so sensitive to ambient temperature as simple cycle gas turbine.
