Selas Refrak Screen Burners

Sealed-in tunnel burners with superior flame retention and combustion characteristics.


Two Models For Superior Combustion Control For Furnace Temperatures Up To 2100°F and Over 2100°F

The Selas Refrak Screen burner is a sealed-in tunnel burner with superior flame retention and combustion characteristics. The RSA’s large perforated refractory screen distributes the air/gas fuel mixture uniformly within the tunnel and assures complete combustion over an extremely wide throttling range. The Refrak Screen Burner has many advantages such as a wide operating range, low operating pressure, complete combustion, easy installation, easy replacement, low velocity and short flame.

Selas offers two kinds of Refrak Screen burners. Burners for furnace temperatures up to 2100°F are available in eight standard sizes for capacities up to 4,000,000 Btu/hr and for wall thicknesses from 6 3⁄4″ to 12 1⁄2″. Burners for furnace temperatures above 2100°F are available in 11 sizes fabricated to specific wall thickness.

S123 Refrak Screen Burners are recommended where furnace temperatures exceed 2100°F. Employing the same refractory port system as the RSA series, S123 burners maintain the same operating characteristics. Because of the higher temperatures encountered, however, it is not practical to offer the piloting and safety accessories available with RSA equipment.

S123 Burners are produced in a wide range of sizes and are fabricated to specific wall thickness. Easy to install and maintain, they provide an economical answer to high temperature requirements. Maximum operating temperature remains a function of furnace design, operating cycle, and turndown requirements.
