Abstract
A paper web in a paper machine including a yankee dryer is dried and the moisture profile thereof controlled by arraying a plurality of gas burners in a cross-machine direction within the hood of the yankee dryer to direct heat toward different incremental width portions of the paper web. The burners are independently controlled by a scanning moisture gauge.
