Definitions

  • the invention relates to a combustion chamber for boilers, in particular with oil firing, from sections which can be placed next to one another, preferably freely set up, to form a trough-shaped or preferably tubular unit enclosing the flame, which in turn are constructed from floor and / or wall elements and are arranged in the combustion chamber of the boiler.
  • Combustion chambers of this type are known. They serve among other things for the subsequent conversion of a boiler from a firing with solid fuels, e.g. Coal, on oil burner. Above all, the combustion chamber should ensure correct guidance of the heating gas and prevent it from reaching the chimney in a short way without transferring its heat content to the boiler.
  • the combustion chamber also serves to protect the boiler against local overheating or hypothermia.
  • the flame of an oil burner has a very different temperature distribution, with the maximum temperature being reached at a relatively great distance from the burner nozzles. Without protective measures for the boiler, there is therefore a risk that the boiler parts exposed to the hot flame areas will be damaged by overheating, while, on the other hand, deposits may form on the boiler parts exposed to the cold flame zones, which, due to chemically aggressive constituents, become one Corrosion of the boiler can lead and otherwise hinder the heat transfer from the flame to the boiler.
  • a combustion chamber with correspondingly arranged outlet paths for the heating gases on the other hand, uniform heating of the boiler can be achieved without any problems.
  • the combustion chamber reflects the heat emitted by the flame back onto the flame, so that an increased flame temperature can be achieved.
  • even flame-retardant components of the oil-air mixture can be broken down and burned. This afterburning of the oil flame ensures a small amount of pollutants in the fire exhaust gases, so that the pollution of the atmosphere is significantly reduced.
  • Known combustion chambers consist of chamotte shaped bricks of different shapes.
  • the sections of which can be assembled into a tubular unit each consist of a flat base plate and semi-arch parts which can be placed thereon and which can be assembled into a U-shaped arch part, the legs of which are held in grooves on the base plate .
  • the object of the invention is now to create a combustion chamber, the shape and dimensions of which can be adapted to different combustion chambers and which consists of as few different parts as possible.
  • sections of the combustion chamber are constructed from interchangeably similar plate elements with a substantially rectangular shape in plan view.
  • tubular or trough-shaped combustion chambers with practically any cross-sections can be created; the plate elements only need to be held against one another or against floor or wall surfaces of the combustion chamber, if necessary, by supporting or connecting elements.
  • a self-supporting combustion chamber can easily be achieved if it is constructed from one or more sections, each composed of three plate elements, with an approximately triangular cross-section. This triangular shape of the combustion chamber is a surprisingly favorable compromise in terms of simple construction and favorable influencing of the flame, in particular by reflection of the heat radiation emanating from the flame.
  • the plate elements can be arched in order to be able to approximate the combustion chamber cross-section to the shape of a circle or arc, so that a particularly large interior can be reached with given external dimensions.
  • edge areas which are thickened or folded over to the outside of the combustion chamber are expediently arranged, which allow the plate element to be supported on a support surface, for example the bottom surface of the combustion chamber, preferably at a distance therefrom.
  • the folded or thickened Edge areas serve as feet or supports of the plate elements and ensure a tilt-proof arrangement even if the latter are curved.
  • wedge-shaped, thickened corner regions are preferably formed on the outside thereof.
  • support strips extending over the length of the plate elements can also be arranged. When the plate elements are supported on the walls of the combustion chamber, these strips serve to keep space outside the combustion chamber for the guidance of the flue gases within the combustion chamber.
  • the thickenings or the like for the arrangement of grooves, holes. serve in which connecting elements can be used to hold the plate elements together in sections.
  • the grooves and tongues can expediently serve to assemble a plate element arranged as the base plate of the combustion chamber with plate elements which serve as side plates and which can rest on a combustion chamber wall at their edge facing away from the base plate. With appropriate training, the grooves and tongues enable the plate elements to be joined together at different angles. Trough-shaped combustion chambers can thus also be assembled, for example.
  • the plate elements can have, at their edges abutting adjacent plate elements within a section, a bore arranged approximately parallel to the edge for receiving pins, clamps or the like.
  • interlocking projections and depressions can be arranged on the plate elements for their section-wise connection at abutting edges. This eliminates the need for separate connecting means for holding the plate elements together.
  • the projections can expediently be arranged as tongues or tabs extending essentially in the plane of the plate, between which recesses with a width approximately corresponding to the tongue or tab width remain free.
  • openings for example in the form of perforated patterns, and openings must be arranged on the plate elements. This is facilitated if the plate elements have embossments that facilitate piercing the plate elements to form openings or a hole pattern to be specified.
  • the plate elements preferably consist of a ceramic fiber material, in particular of alumina silicate fibers. Such materials are characterized by their low weight and high fire resistance and, similar to cardboard or the like, can be processed in a simple manner with cutting tools.
  • the ceramic fiber materials can be cast in any shape so that, if desired, complicated shaped elements can also be produced.
  • combustion chamber is preferably constructed from plate elements that are particularly easy to store and ship when manufactured from ceramic fiber materials
  • the invention also generally includes combustion chamber elements made from such materials.
  • the invention is not limited to plate elements made of alumina silicate fibers. Rather, the plate elements can also be formed as stamped parts from sheet metal or as metal cast parts or consist of chamottes.
  • the plate elements can consist of half-plates joined together, so that, if necessary, an even greater variability with regard to the combustion chamber dimensions can be achieved.
  • the plate element 1 shown in Fig. 1 is a cast part made of refractory ceramic fibers, e.g. Alumina silicate fibers and in particular aluminum silicate fibers.
  • the fibers are processed in a manner known per se with a hydraulic-ceramic binder in a vacuum molding process with subsequent oven drying.
  • the plate element 1 consists essentially of a curved rectangular plate 2, at the corner areas of which wedge-shaped thickenings 3 are formed on the concave side of the plate 2. These thickenings 3 allow the plate element 1 to be placed on a flat floor surface, for example the floor of the combustion chamber of a boiler, so that it cannot tip over.
  • bores 4 are arranged parallel to the non-curved edge of the plate 2. These holes 4 or the like for receiving pins, brackets. (Not shown) are used to connect several plate elements 1 to one another or to anchor them in the combustion chamber of a boiler.
  • a rectangular recess 5 is arranged on the one non-curved edge of the plate 2 between the thickenings 3, while a rectangular tongue 6 continuing the plate 2 and having a size corresponding approximately to the recess 5 is formed on the opposite edge.
  • Recesses 7 are embossed on the plate 2, which facilitate piercing the plate 2 to form openings or hole patterns.
  • the plate elements 1 can be assembled into sections 8 which can be set up one behind the other and have a triangular cross section.
  • the tongues 6 of a plate element 1 are each inserted into the recesses 5 of an adjacent plate element 1.
  • Several sections 8 arranged one behind the other form a tubular unit which, as a combustion chamber, has a flame (not shown) of an oil burner or the like. encloses.
  • an end plate 9 can be arranged at one end, preferably also made of a ceramic fiber material, which is inserted with extensions 10 into slot-like recesses, which are arranged on the plate elements 1 of the last section and can be produced by corresponding depressions 7 '(see FIG. 1) of the plate elements 1 are pierced.
  • the end plate 9 diverts the counter-impinging heating gases into a counterflow which, enclosing the flame, sweeps along the walls of the combustion chamber.
  • the heating gases then escape from the combustion chamber through openings arranged in the plate elements or through spaces between the individual sections 8, which are optionally placed one behind the other at a distance.
  • the sections 8 shown in FIG. 2 are self-supporting. If necessary, however, 4 clamps 11 can be inserted into the bores for additional securing, which connect adjacent plate elements 1 to one another.
  • fire-resistant cords made of ceramic fiber materials can also be used.
  • the plate elements 1 can also be connected to one another by means of a ceramic cement.
  • the plate element 1 according to FIG. 3 differs from the plate element according to FIG. 1 essentially in that instead of the wedge-shaped thickenings, two continuous support strips 30, 31 are arranged, which allow the plate element 1 to be placed on a flat surface against tipping and to stiffen the plate element 1 contribute.
  • the one support strip 31 is arranged at a distance from the edge 2 'of the plate 2 of the plate element 1, so that the edge 2' is optionally removed, e.g. can be cut off if the width of the plate 2 is to be reduced.
  • opposing grooves 32 and springs 33 are arranged, which allow a connection of the plate element 1 with other plate elements at largely any angle, so that, for example, trough-shaped combustion chambers can be built by one on the firebox floor
  • Overlying plate element laterally plate elements are attached by means of the grooves 32 and springs 33 and are supported, for example, on the side walls of the combustion chamber.
