Definitions
- the invention relates to a combustion cylinder for premixed forced draft burners of gas heating devices according to the preamble of the main claim.
- fan burners are used in which a mixture of fuel gas and air, which is usually pre-stoichiometrically premixed before the flame is formed, is fed to a preferably arranged hanging cylinder in the gas heater, which has a flame holding cylinder made of perforated, heat-resistant sheet metal material on the outer wall, on which the flame formation takes place .
- a modern development of the aforementioned combustion cylinder has two further cylinders, also made of perforated heat-resistant sheet metal material, namely in the flame holding cylinder with a radial distance a distribution cylinder and in this with a radial distance a throttle cylinder.
- connection flange which contains the opening for the entry of the mixture into the combustion cylinder and a cover which closes the opposite end of the combustion cylinder
- connection flange and the cover being formed with three concentric annular grooves into which the three cylinders are located with their edges are inserted.
- the outer flame holding cylinder is fastened at both edges in the annular groove of the connection flange and the cover by means of several radial screw bolts in order to hold the connection flange and the cover and thus the entire combustion cylinder together.
- the distribution cylinder and the throttle cylinder are, however, in the most common hanging arrangement of the combustion cylinder with the cover located at the bottom only in the ring grooves of the cover by means of the radial screw bolts and axially movable at the top in the ring grooves of the connecting flange, so that the connecting flange and cover can change their distance from one another when the outer flame holding cylinder, which is most subjected to temperature changes, changes its axial length. It is necessary to seal the edges of the flame holding cylinder fastened in the ring grooves of the connecting flange and the cover also by inlaid, high-temperature-resistant special seals, since gas leaks at the bordered edges of the flame holding cylinder would considerably disrupt the flame formation and the combustion.
- the construction and assembly of the known fuel cylinder are also relatively complex due to the design of the cast flange and the cast cover with three concentric receiving ring grooves for all three sheet metal cylinders and by attaching the sheet metal cylinder in the receiving grooves by means of several radial bolts.
- the invention therefore has for its object to design the combustion cylinder of the type mentioned in such a way that both the flame holding cylinder and the distribution cylinder on both edges with a secure gas-tight connection, which does not necessarily have to have an axial mobility of the cylinder edges, to the connecting flange and the lid is connected and the strongly heated flame holding cylinder can still perform sufficient axial elongation to avoid mechanical stress cracks.
- the manufacture and assembly of the combustion cylinder should be made easier.
- combustion cylinder design according to the invention is described in more detail below with reference to the embodiment shown in the drawing in axial longitudinal section.
- the combustion cylinder has at its upper end a conical connecting flange 1 which has the opening 14 for the entry of the combustible mixture into the combustion cylinder contains, and at its lower end a closed cover 2. Between the connecting flange 1 and the cover 2, an outer flame holding cylinder 3, a middle distribution cylinder 4 and an inner throttle cylinder 5 are arranged. These three cylinders are made of perforated heat-resistant sheet metal and are arranged concentrically with a radial distance from each other.
- the connecting flange 1 and the cover 2 are not cast parts as in the conventional combustion cylinders described above, but also consist of heat-resistant sheet metal material and are formed by sheet metal drawing, which is much easier and cheaper than the customary production of these two parts of the combustion cylinder from cast iron. It also makes the weight of the combustion cylinder much lighter.
- the cover 2 consists in two parts of an inner cover plate 7 and an outer cover plate 8. The complete combustion cylinder is held together by the central distribution cylinder 4, which is firmly connected at both edges and essentially sealed to the connecting flange 1 and the inner cover plate 7. At the lower edge, the distribution cylinder 4 is fastened to an upwardly directed edge flange 15 of the inner cover plate 7 by spot welding.
- the lower edge of the inner throttle cylinder 5 adjoins the lid inner plate 7 when not fastened.
- the distribution cylinder 4 and the throttle cylinder 5 are fastened together by spot welding to bolts 12, which can be inserted in the axial direction of the combustion cylinder through bolt holes in the connecting flange 1 and screwed to the connecting flange.
- bolts 12 By means of these axial screw bolts 12, the two cylinders 4 and 5 can be conveniently connected to the connecting flange 1 during assembly of the combustion cylinder and by simply pulling their edges onto the connecting flange 1 into a sufficiently gas-tight contact with the connecting flange 1 are brought.
- the heating and axial expansion of the distribution cylinder 4 during operation of the burner is significantly less than that of the incandescent flame holding cylinder 3, so that the change in distance between the connecting flange 1 and cover 2 is kept correspondingly small and a gap formation between the lower edge of the less than the distribution cylinder is heated and axially expanding throttle cylinder and the inner cover plate 7 arises, the throttle function of the throttle cylinder 5 is not significantly influenced.
- the extremely strongly heating flame holding cylinder 3 is received on both edges by annular groove-like brackets 6 of the connecting flange 1 and the cover 2, in which the flame holding cylinder 3 is axially movable and also radially movable due to the diameter changes which also occur with the temperature changes.
- the annular groove-like brackets 6 are formed by U-shaped edge flanges 13, which can be produced by sheet metal drawing, on the connecting flange 1 made of sheet metal and on the cover outer plate 8 made of sheet metal.
- the cover inner plate 7 fastened to the distribution cylinder 4 and the cover outer plate 8 holding the flame holding cylinder 3 are shown by a Embodiment from a screw 9 arranged at the center of the lid held together by a compression spring 10, by means of which the outer plate 8 can be pressed resiliently from the inner plate 7 is.
- a compression spring 10 arranged at the center of the lid held together by a compression spring 10
- the outer plate 8 can be pressed resiliently from the inner plate 7 is.
- the axially resilient connection of the two cover plates 7 and 8 expediently additionally includes an anti-rotation device which consists of pins 11 which are fastened to the cover inner plate 7 and engage in guide holes in the cover outer plate 8 with axial displacement.
