Abstract
A device for heating open melting baths, especially galvanizing baths, enameling baths, lead coating baths, metal baths, and glass baths, and the like, in tubs, or vats or tanks, wherein an inert gas is circulated through components of the open baths which are closed toward the gas side which are in the form of shafts, and through a heater, whereby the gas is introduced into the fluid of the bath into vertical shafts, arranged on each longitudinal and/or end side of the tub, or vat or tank, the gas then bubbling through the fluid and being withdrawn through a withdrawal channel positioned above the shafts. There is provided at least one ceramic partition extending into the fluid, which partition forms at least part of the vertical shafts, and having at least one bore or a slot the upper end of which is in communication with the gas inlet conduit and the lower end of which opens into a pertaining vertical shaft or has provisions for directing the gas into the shaft.
