Dual structure infrared surface combustion burner
This patent describes an improvement in a surface combustion radiant heat burner comprising an inlet plenum for receiving fuel and oxidant gas mixtures from at least one supply inlet and a burner body secured in communication with the inlet plenum. The burner body having an inlet side facing the plenum and an outlet side defining a radiating surface. It comprises: the burner body comprising a first layer of porous ceramic material adjacent the inlet side and a second layer of porous ceramic material adjacent the outlet side defining the radiating surface, the first layer of porous ceramic material having a thickness of at least about 0.90:01 inch and a fine interconnected porous structure with a mean pore diameter ranging from 0.00004 inch to 0.10 inch, the second layer of porous ceramic material having a thickness of at least about 0.05 inch and a coarse interconnected porous structure with a mean diameter ranging from 0.05 to 0.40 inch, and at least the outer surfaces of the first porous layer and substantially all surfaces of the second porous layer being provided with a fully dense ceramic coating.
