A regenerative bed is operated in a separate, additional cleaning cycle by heating the regenerative bed media to a temperature above the condensation temperature of contaminants in order to liquify and drain of the same off of the bed media. In the preferred embodiment shown, this is accomplished by over riding the normal cycling of the regenerative beds so as to retain a subject bed in a fluing mode for an abnormal amount of time (trading bed efficiency for the heating of the bed). The beds preferably also incorporate an escape opening 13 to drain off the contaminants.

In a burner having a regenerative bed, which regenerative bed is prone to the solidification of contaminants from the material being heated within the furnace due to the existence within the regenerative bed of bed media having a temperature lower than the solidifying temperature of such contaminant

In a burner having a regenerative bed, which regenerative bed is prone to the solidification of contaminants from the material being heated within the furnace due to the existence within the regenerative bed of bed media having a temperature lower than the solidifying temperature of such contaminant material, the improvement comprising means to heat the bed media in the regenerative bed to above the solidifying temperature of the contaminants such that the contaminants are unsolidified and means to drain off the unsolidified contaminants from the regenerative bed.
