METHOD AND APPARATUS FOR REDUCING NITROUS OXIDES AND CO-EMISSIONS IN A GAS-FIRED RECUPERATED RADIANT TUBE BURNER

摘要

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 (4), exhaust section (8), radiant tube (3), plenum (2) and a jet pump assembly (1). A volume of exhaust gas drawn from the stream of exhaust gases into the jet pump assembly (1) by way of a motive gas (24) is flowed into a stream of combustion air (16) so as to vitiate the oxygen content of the combustion mixture. When the combustion mixture is combusted with fuel (56) in the burner section (4), the production of nitrous oxides and other harmful emission is mitigated.
