<p>A process for drying a web of material (12) moving at a speed of at least about 150 feet per minute. In the first step of the process, a web of material is contacted with a first mixture of air and flue gas while passing the web under a first air nozzle (28). Thereafter, a portion of the first air/flue gas mixture is exhausted through a first exhaust nozzle disposed less than 12 inches away from the first air nozzle. Thereafter, the web is passed under a multiplicity of gas fired infrared radiation emitting burners (34, 36, 38, 40, 42 and 44) while contacting said moving web with infrared radiation and flue gas and heating said moving web to a temperature of from about 100 to about 280 degrees Fahrenheit. Thereafter, the web is contacted with a second mixture of air and flue gas while passing it under a second air nozzle.</p> |
