Abstract

Boilers with horizontal boiler sections contain in each section several heat exchanger elements for transferring the heat from the heating medium to the heat carrier medium. They have the inherent advantage of needing a connection between sections only on one side so that the dimensional changes during operations are easily equalized and no thermal stresses occur. Heretofore, it has been assumed that the frame of such horizontal boiler sections in which the heat exchanger elements in the form of pipes are secured must be provided with a cooling channel for the liquid heat carrier medium, and consequently the specific heat output in relation to the amount of material used for the construction of the boiler section was considerably decreased. The boilers with horizontal sections in accordance with the invention overcome this problem and require only a reduced specific amount of material as compared with the known boilers of this type. This is achieved by providing the boiler sections with a solid frame which is in heat conductive contact with at least the adjacent pipe or pipes conducting the heat carrier medium by means of the fin or fins provided on the pipes, preferrably by means …
