PURPOSE: A multi-swirl combustor plate is provided to reduce the producing of NOx and to maintain excellent combustion property by receiving multiple swirlers arranged on many concentric rings installed in one board of a combustion device. CONSTITUTION: A multi-swirl combustor plate receives multiple swirlers arranged around the inner part of a combustor plate and multiple non-swirling holes arranged around the outer part of a plate(102) molded to be hard. The swirlers are arranged on the concentric circle, and the non-swirling holes are formed on the other concentric circle placed on the outer part of the swirlers. The swirlers includes an outer wall(210) having a wall more thicker than one of the multi-swirl plate, and are the extended part of the multi-swirl plate arranged in the direction of the lower course. Likewise, a swirl hub(212) has a wall thicker than one of the board, and is the extended part of the multi-swirl plate.
