A high heat flux catalytic radiant burner of the present invention includes a housing with an inlet and an outlet end. A catalyst layer which has a coating disposed on a support is positioned between the two ends. The catalyst layer has a total specific surface area of 0.1 to 10 m.sup.2 /g. The support has a specific surface area of 1 m.sup.2 /g or less. The coating is a thin film of a nobel metal. A mixture of air and gas enters the housing though the inlet end and enters the catalyst layer where the gas is oxidized and releases heat such that the burner maintains operational firing rates of approximately 40 to 413 kBTU/hr ft.sup.2 and produces extremely low emissions.

[ What is claimed is:] [1.] In a high heat flux catalytic radiant burner, a method for producing radiant heat comprising the steps of:mixing a gas with air in a mixing zone to form a premix;propelling said premix by using a blower to blow said premix into a housing through an inlet end of said housing so that all oxygen entering said housing enters with said premix;providing said premix to an upstream face of a catalyst layer having a coating formed from a thin film of a noble metal on a porous support having a specific surface area of 1 m.sup.2 /g or less, said catalyst layer having a specific surface area of 0.1 to 10 m.sup.2 /g when said coating is on said porous support;oxidizing said gas of said premix by said catalyst layer and said air in said premix without diffusion of air from the atmosphere through said downstream face; andproducing an operational firing rate of approximately 40 to 413 kBTU/hr ft.sup.2, so that said catalyst layer reduces blockage of pores in said catalyst layer, maintains high temperatures and raises efficiency of the burner.
