A combustor method and apparatus is provided. The method utilizes flameless combustion. The absence of a flame eliminates the flame as a radiant heat source and results in a more even temperature distribution throughout the length of the burner. Flameless combustion is accomplished by preheating the fuel and the combustion air to a temperature above the autoignition temperature of the mixture. The present invention lowers the autoignition temperature by placing a catalytic surface within the desired combustion chamber. Temperatures are maintained above the catalyzed autoignition temperature but less than the noncatalyzed autoignition temperatures for noncatalyzed reaction. Thus, the amount and location of reaction can be controlled by varying the amount and distribution of catalyst within the burner. Removing heat from the combustion chamber in amounts that correspond to the oxidation of fuel within different segments of the combustion chamber can result in low temperatures and relatively even distribution of heat from the burner.

[ We claim:] [1.] A flameless combustor for combustion of a fuel and oxidant mixture, the combustor comprising:a combustion chamber in communication with an inlet at one end and in communication with a combustion product outlet at the other end;a mixed fuel and oxidant supply in communication with the inlet;a preheat section wherein in the preheat section heat can be exchanged between the fuel and oxidant mixture and the combustion products; anda catalyst surface within the combustion chamber wherein the catalyst surface is effective to cause oxidization of an amount of fuel wherein the oxidation of the amount of fuel does not result in a temperature above an uncatalyzed autoignition temperature of the fuel and oxidant mixture.
