Afton Combined Cycle with Hybrid Cooling

摘要

The Afton Generating Station near Las Cruces, N.M., is a 225 MW-dass 1×1 combined cycle project owned and operated by Public Service Co. of New Mexico (PNM). The preliminary design efforts moved through five distinct configurations to reach the final design. The facility represents the state of the art in combined cycles, including unique parallel path water conserving hybrid cooling system. This cooling system is applicable for consideration at all plant sites facing water constraints.rnThe project was first conceived in 2001 as a 100 percent wet-cooled 550 MW 2×2×1 Frame 7FA unit. This prompted PNM to procure the gas turbines and steam turbine from General Electric and construct one simple cycle turbine as Phase I.
