ABSTRACT:
The operational capacity and efficiency of a combustion turbine is increased by treating the turbine inlet air to increase its density. The inlet air treatment is achieved in a columnar tower with the inlet air being drawn in at the top of the tower. Treatment water is injected into the tower at a downward velocity greater than that of the inlet air to establish a vertically descending, two-phase co-current flow of inlet air and treatment water. The system utilizes the natural phenomenon of drag-induced pressure boost to the air achieved by the difference in the relative velocities of the inlet air and the treatment water in the co-current flow. By utilizing a cold treatment water, for example at 32.degree.-40.degree. F., the tower creates a direct contact heat transfer situation that cools the inlet air, thereby further increasing its density. The invention serves to increase the operational capacity and efficiency of existing or new peaking combustion turbines at a cost per kW that is substantially less than that of installing new peaking combustion turbine capacity, while also permitting enhanced load following capabilities for the electric utility's control center.
