Title: TEMPERED AMMONIA INJECTION FOR GAS TURBINE SELECTIVE CATALYST REDUCTION SYSTEM
Abstract:
The present application provides a selective catalyst reduction system for use with a combustion gas stream of a gas turbine. The selective catalyst reduction system may include an inlet positioned about the gas turbine, a combined ammonia-tempering air injection grid positioned about the inlet, and a catalyst positioned downstream of the combined ammonia-tempering air injection grid. The combined ammonia-tempering air injection grid injects air and ammonia into the combustion gas stream upstream of the catalyst.
