Abstract
A regenerative burner device for a furnace and a method of removing contaminants from such a device. The burner device includes a burner for introducing heat and waste gas into a furnace during ignition when supplied with fuel and a combustion gas, a media bed comprising refractory particles, and ducting for delivering combustion gas to said burner during ignition, and for drawing waste gas from said furnace on termination of ignition. The ducting causes the combustion gas and the waste gas to pass in succession through the media bed. Means are provided for periodically delivering a rapid flow of a decontaminating gas into said media bed. The rapid flow is of sufficient force to dislodge contaminants collected in the media bed from said waste gas.
