Abstract
A radiant tube burner assembly and method is provided to reduce nitrous oxides and carbon monoxide emissions in the combustion of hydrocarbon fuels. The burner assembly comprises a burner section, exhaust section, radiant tube, plenum and a jet pump assembly. A volume of exhaust gas drawn from the stream of exhaust gases into the jet pump assembly by way of a motive gas is flowed into a stream of combustion air so as to vitiate the oxygen content of the combustion mixture. When the combustion mixture is combusted with fuel in the burner section, the production of nitrous oxides and other harmful emission is mitigated.
