Abstract

A dual flow distribution header system in which the flow is divided into two paths before the distribution header but after a metering device. The flow is controlled by separate butterfly valves in each path, whereby the control function is magnified and becomes more precise in each path. The invention is particularly adapted for use with industrial heating furnaces employing dual burner systems.
