Intense flue-gas recirculation from high-momentum jet flames improves temperature uniformity and lowers emissions.
High-momentum jet flames are widely used in different industrial applications, such as radiant-tube heating, to develop intensive flue gas recirculation for better forced convection heat transfer and temperature uniformity in the working chamber. Four major types of radiant-tube burner working-chamber geometries are: coaxial tubes (SER, or single-ended recuperative design), "U", "W" and "P" shapes. The main design advantages and performance of Eclipse's Auto-Recupe burner mounted inside an SER radiant tube are discussed. The burner uses high-momentum flame technology to meet industry requirements and environmental regulations.
