Abstract

A furnace over at least part of its outer surface is provided with a double wall, the space enclosed by said double wall being part of a circulation system for cooling liquid without pressure, there being a reservoir above the double wall space in which vaporized cooling liquid can be separated from the cooling mixture, which reservoir is in communication with the upper end and the lower end of the double wall space, the reservoir being in direct open communication with the upper end of the double wall space and being positioned immediately on top thereof and the double wall space being divided into two spaces by an intermediary baffle about parallel to the outer surface of the furnace, said two spaces being in open communication with each other at their upper and lower ends. The reservoir may extend from the upper end of the double wall space in upward and widening outward direction with respect to the furnace wall and may have at least one discharge duct for vapour connected thereto in the proximity of the highest and most outward area of this reservoir may have in the proximity of the upper end of the double wall space, at the outside thereof, as part of the supply system for cooling liquid a liquid reservoir with an overflow which is connected to the space within the double wall through a narrow connecting passage and may include other structural features.
