A radiant burner for treating an effluent gas stream from a manufacturing process tool may include: a combustion chamber having a porous sleeve through which combustion materials pass for combustion proximate to a combustion surface of the porous sleeve; and a plenum surrounding the porous sleeve supplying the combustion materials to the porous sleeve, the plenum being configured to provide the combustion materials with varying stoichiometry along a length of the porous sleeve. This approach of varying the stoichiometric ratios of the combustion materials correspondingly varies the heat generated by those combustion materials along the length of the porous sleeve. By varying the stoichiometry of the combustion materials to compensate for variations in the heat generated within the combustion chamber along the length of the porous sleeve, a more uniform temperature can be achieved along the length of the porous sleeve within the combustion chamber. |
