Selas Ribbon Burners Offer A Variety Of Heating Techniques.

Filaments for lamps are preheated ahead of drawing dies, as shown here. Fine sewing threads are singed in multiple strands. Copper alloy wire is heated in this way for annealing.
Webs are dried, cured or preheated by directing the burner flames against the passing material. Flames are uniform to be used for textile singeing. Electrical static is discharged by flame conduction.
Parts of many shapes and materials are handled on conveyors as shown. Fabricated pieces of steel, glass and nonferrous materials are heated for hardening, tempering, annealing or hot forming.
Air is heated for many purposes by inducing (or forcing) it over ribbon burners within insulated chambers. Applications include drying, enamel baking, food preparation, curing and other similar uses.
Conveyors of ovens, furnaces, and lehrs are preheated to offset effects of cooling during return travel. This practice increases production and reduces thermal shock to previously heated ware.
Rolls for calendering are normally gas fired internally. This arrangement of ribbon burners provides uniform lateral heat distribution. Rolls without internal accessibility may be externally fired.
Wire is conveniently cured after coating by conveying it vertically through special ribbon burners. Multiple strands are heated simultaneously. Burner manifolds are retractable for accessibility.
Glassware must be fire -polished or "glazed", to eliminate sharp molded edges that might injure the user. Glazing is performed by fusing the sharp edges while the ware is continuously conveyed through ribbon flames.
