Abstract
Colorless distributed combustion (CDC) reactors or green combustion gas turbine combustors having a combustion chamber are presented for improved performance of gas turbine combustion engines. The combustors are configured and designed for providing a superior pattern factor (uniform thermal field in the combustion zone) and a reduction or complete elimination of pollutants emission from the combustor (i.e., zero emission gas turbine combustor) and uniform thermal field in the entire combustion zone to provide significantly improved pattern factor. Colorless distributed combustion is achieved with fuel and air entering the combustion chamber via one or more injection ports as non-premixed, or premixed. Rectangular, cylindrical, stadium and elliptical shaped combustors are presented with injection ports and exit ports located in various locations of the combustors. The mixture preparation between fuel and air with the hot combustion products is carried out either with the gases present in the combustion chamber or via a communication link between the exit gases from the combustor back to the combustion chamber.
