Abstract: The present application provides a selective catalyst reduction system for use with a combustion gas stream. The selective catalyst reduction system may include a tempering air system with a finger mixer and a number of mixing boxes positioned downstream of the finger mixer and a catalyst positioned downstream of the tempering air system. The tempering air system cools the combustion gas stream and evens out the temperature profile before the combustion gas stream reaches the catalyst.
