Uniformization of furnace temperature distributionFigure 3 shows ordinary combustion (left) and high temperature air combustion (right, ENX-P) .Combustion generally proceeds rapidly in the vicinity of the burner, where local high temperature zones occur.Then, the temperature distribution in the furnace becomes higher at the center of the furnace.On the other hand, since ENX-P burns slowly throughout the furnace based on high temperature air combustion,the temperature distribution in the furnace becomes uniform.As the result, miniaturization of the furnace, improvement of the quality of heating object, and reduction of NOx emission become possible.
