Apparatus and method for cleaning regenerative-burner media bed

摘要

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.

1. A regenerative burner device for a furnace, comprising:
a burner for periodically introducing heat and waste gas into a furnace during ignition when supplied with fuel and a combustion gas, a media bed comprising refractory particles, ducting for delivering combustion gas to said burner during said ignition, and for drawing waste gas from said furnace on termination of said ignition, said ducting causing said combustion gas and said waste gas to pass in succession through said media bed; a source of decontaminating gas under pressure; and delivery tubing having a stationary outlet positioned adjacent the media bed for delivering a decontaminating gas pulse to the media bed in less than one second, wherein the decontaminating gas pulse is of sufficient force to cause the refractory particles to bounce and thereby to dislodge contaminants collected in the media bed from the waste gas.
