Abstract
Control system and method for regulating the air/fuel mix of a burner for a web dryer or a regenerative or recuperative oxidizer, for example. Differential air pressure is monitored between the air chamber of the burner and the enclosure into which the burner fires (such as a flotation dryer or the combustion chamber of a regenerative thermal oxidizer). Fuel flow is monitored by a differential pressure measurement between the fuel chamber of the burner and the enclosure into which the burner fires. These measurements are compared to predetermined values, and the fuel flow and/or air flow to the burner is regulated accordingly.
