Abstract
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.
