ABSTRACT:
A carbon desorption heater (10) for use in a system for removing volatile organic contaminants from a carbon filter is disclosed as having a housing (30) in which a recirculating heating circuit (36) is provided with a recirculation blower (44) that moves the air past a burner (50) for flow through a first flow path (60) of a heat exchanger (58) with a portion of the recirculated air exhausted during each cycle of flow through an exhaust stack outlet (52). A delivery blower (64) within the housing (30) moves air through a second flow path (62) of the heat exchanger (58) for heating prior to delivery to a supply outlet (34). The heater includes a plurality of modules (90) that are sufficiently small so as to be shippable and subsequently securable to each other at the factory site where the heater is to be used. Insulated walls (94, 96, 98, 100) cooperate to define a heating chamber (106) in which the recirculating heating circuit (36) is located, while an outer wall (108) cooperates with certain of the insulated walls to provide a control chamber (110) in which the control equipment of the heater is located for adjustment and maintenance.
