摘要： An improved burner assembly and process for operating same using a burner design that produces very low levels of undesirable nitrogen oxides is provided. The burner assembly premixes primary fuel and air in a venturi system and recirculates combustion gases back to the burner through a plurality of recirculation conduits where it is mixed with the premix of fuel and air and secondary air prior to combustion in a primary combustion zone. Rapid premixing of the primary fuel and air in the venturi system and the dispersion of the recirculated furnace gases is believed to result in lower peak flame temperatures and therefore minimizing the formation of the pollutants, such as nitrogen oxides.

摘要： A fired equipment system and process for operating same is provided that combines stationary industrial burner technology and a catalyst bed that converts pollutants formed during combustion of fuel and air in the burner to yield stack gases that need no further treatment before discharge to the atmosphere. The system and process disclosed reduces CO, NOx and VOC's by at least 90 to 95%.
