Abstract
Apparatus for heating the recirculated air from a web dryer in such a manner that the recirculated air does not come in direct contact with the flame of the burner in which the fuel and air for combustion are mixed and burned. Because the solvent-laden recirculated air does not come in contact with the flame, alteration or partial incineration of the hydrocarbons does not occur. When printing inks are formulated with non-photochemically reactive solvents and used in conjunction with the present apparatus, other methods of solvent collection are available for air pollution control instead of energy-consuming incineration (thermal or catalytic); and in some cases no control method is required. The present apparatus provides an area for the complete combustion of the fuel/air mixture from the burner before leaving the containment tube and mixing with the recirculated air.
