Collective heating boiler in three-pass design for flowing fuels

The innovation concerns a collective heating boiler in three-pass construction for flowing fuels. The job of hiring is to design a boiler of this type in such a way that its ¥ / exchange pipes (return and pre-flow) are easy to install and clean.

According to the innovation, the sleek flame tube has a water-cooled constriction at the beginning and a water-cooled one at the end Dome-shaped, axially slidable supported in their center on the boiler Turning chamber, the diameter of which is larger than the diameter of the flame tube; to the dome-shaped turning chamber are connected to a widening equiaxed cone shell tubular return flow members, which in a front reversal comb he open, and from the front reversing chamber arranged on a concentric cylinder lead pre-flow trains into one Exhaust collector.

Through the flame tube in connection with the turning chamber and the constriction at the start of the flame tube, which only has one opening for the: Leaving the combustion head of the burner free, a combustion chamber is formed that is cooled on all sides, so that the whole of the flame emanates from the flame.

de radiant heat is supplied to the boiler water. The ge ^ . Arched bottom that delimits the turning chamber: in the axial direction ", directs the hot gases to the return lines without great pressure loss out, with the concentric connection of the return flows a Uniform exposure of the flame tube and the reversible chamber with heating gases. In addition, the spherical shape is mechanical favorable ^ it takes the "pressure forces acting from the water space" on. The axially slidable "support on the boiler leaves a free movement of the flame tube with its turning chamber opposite to the boiler.

Because the diameter of the turning chamber is larger than the diameter of the flame tube, you can here without difficulty. Connect return flows, e.g. weld on. One can be 4be ring-shaped Give the surface between the flame tube and the outer jacket of the turning chamber a relatively small radial extension, which does not significantly exceed the diameter of the return pipes. These return pipes lead slightly outwards at an angle a reversal chamber, whereby the cross-section of the reversal chamber is small can be held, because now it is possible to use the Torströmzüge to be arranged axially parallel on a cylinder, the diameter of which. knife is only slightly larger than the diameter of the return pipe outlet openings. . :.

The arrangement is extremely compact and yet ... easy to manufacture. The. _: Heat exchange surfaces are large. .

The sheet metal hood has advantageous / below and above at least each an opening for the free entry and-the-free discharge of Air.
