Method for reducing emissions from a combustor

A modification method for reducing emissions from an annular shaped combustor of a gas turbine plant having uniformly spaced, circumferentially mounted premix burners and a combustor air distribution system, the method comprising:

• removing at least one of said burners thereby disrupting the spatial uniformity of the remaining said burners and creating a modified combustor;
• and
• modifying said combustor air distribution system to compensate for an increase burner pressure drop of said remaining burners, thereby enabling said modified combustor to operate at a load equivalent to the unmodified combustor;
• wherein said removing and said modifying together;
• reducing combustor emissions for a given combustor load by increasing burner velocity from said modifying;
• and
• flame stabilizing by disrupting said spatial uniformity by said removing.
