Heating furnace

摘要

In a heating furnace, a reduction of the building material and heating of the material to be heated (4) on both sides are achieved by providing a plurality of spaced-apart combustion chambers (7-11). The furnace height is so low in furnace sections (15-18) lying between the combustion chambers (8-11) that the draught flue gases pass through both the upper furnace (5) and through the lower furnace (6). <IMAGE>
