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 bath which are closed toward the gas side, and through a heater, whereby the tub, or vat or tank includes at each longitudinal and/or end wall a plurality of conduit means, such as pipes, for introduction of the gas into the bath and whereby the gas is withdrawn above the conduit means through a draft flue at the edge of the tub, or vat or tank, which draft flue includes a vertical partition immersed in the bath. The device includes means for communicating a warm gas receiving means with the container for the melting bath which communicating means includes at least one ceramic block including passage means for communicating the warm gas receiving means with the container.
