Definitions

  • the invention relates to a combustion chamber for boilers, in particular for oil-fired boilers, consisting of at least one section which is wholly or partly enclosing the flame and is formed by floor and wall elements, at the front ends of which an additional or similar section can be connected to form an extended or enlarged combustion chamber.
  • Such a combustion chamber is known from DE-C-931 723.
  • the sections of these known combustion chambers each consist of two semi-U-shaped side parts which can be joined together to form a U part and an optionally open cover plate.
  • a self-supporting construction is not possible, rather the side parts have to be supported on the walls of the boiler.
  • US-A-2 369 965 describes a combustion chamber in the form of a tubular section with a vertical tube axis.
  • the section is composed of a large number of wall parts, the abutting edges of which partially overlap or overlap one another.
  • a self-supporting arrangement of this known combustion chamber with a horizontal axis is not possible. This means that this combustion chamber cannot be used in conventional boilers with oil burners which produce an essentially horizontal flame.
  • the object of the invention is now to create a combustion chamber, the shape and dimensions of which can be adapted to very different combustion chambers and which consists of as few different parts as possible.
  • section or sections are made up of interchangeably identical plate elements which are essentially rectangular in plan view, each having tongues or tabs on two opposite edges and recesses which are approximately the same width as the tongues or have rags and are opposite to each other, such that the tongues of a plate element can be inserted into the corresponding recesses of the plate element adjacent within the respective section.
  • the tongues or tabs and recesses allow the plate elements to be joined together in very different ways, i.e. H. in particular that different cross-sectional shapes of the combustion chamber can be achieved.
  • the tongues or tabs and recesses can be designed such that the plate elements can be connected to self-supporting sections by inserting their tongues or tabs and recesses into one another.
  • the combustion chamber can be constructed from one or more sections, each composed of three plate elements, with an approximately triangular cross section.
  • the plate elements are expediently curved in such a way that the combustion chamber cross section approximates the shape of a circle or arc.
  • combustion chambers according to the invention are particularly suitable for retrofitting, for example when a boiler is fired with solid fuels, such as. B. coal to be converted to an oil burner.
  • the combustion chambers according to the invention can ensure proper guiding of the heating gas in a particularly expedient manner and prevent them from reaching the chimney in a short way without transferring their heat content to the boiler.
  • the combustion chambers can also be used to protect the boiler against local overheating or hypothermia when retrofitted.
  • 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 would lead to corrosion of the boiler due to chemically aggressive components and in the others hinder the heat transfer from the flame to the boiler.
  • the plate elements have embossments which facilitate piercing of the plate elements to form openings, openings or a hole pattern to be specified - on the other hand, uniform heating of the boiler can be achieved without further ado will.
  • the combustion chamber reflects the heat radiated 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.
  • edge regions which are thickened or folded over can be arranged, which place the plate element on a support surface, for example the bottom surface of the fire allow space, preferably at a distance from the same, to support.
  • the folded or thickened edge areas serve as feet or supports of the plate elements and ensure a tilt-proof arrangement even if they are curved.
  • wedge-shaped, thickened corner regions are preferably formed on the outside thereof.
  • strip-like support parts running transversely to the longitudinal axis of the combustion chamber can also be arranged on the plate elements, optionally at a distance from the edge of the plate element. 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.
  • opposite grooves and tongues for connecting adjacent plate elements can be arranged on the edges of the plate elements, preferably on their edges running approximately parallel to the combustion chamber axis.
  • a plate element arranged as the base plate of the combustion chamber can be joined together with plate elements which serve as side plates and which can rest against a wall of the combustion chamber at their edge facing away from the base plate.
  • the grooves and tongues allow the plate elements to be joined together at different angles.
  • trough-shaped combustion chambers can also be assembled in a particularly simple manner.
  • each plate element prefferably has an approximately edge-parallel bore for receiving connecting elements, such as pins, clamps or the like, on its edges which abut against an adjacent plate element within a section.
  • each plate element is light in weight. This can be achieved if each plate element consists of a ceramic fiber material, in particular of alumina silicates, such as aluminum silicates. Such materials are characterized not only by their low weight, but also by their 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 advantageously be cast in any shape so that, if desired, very complicated shaped elements can also be produced.
  • plate elements designed as stamped or cast parts made of metal are also advantageous.
  • the plate elements can also consist of chamottes.
  • the plate elements can consist of half-plates joined together, in order to possibly achieve an even greater variability with regard to the combustion chamber dimensions.
  • the tongues or tabs preferably extend essentially in the plane of the plate.
  • the plate element 1 shown in Fig. 1 is a casting made of refractory ceramic fibers, such as. B. alumina silicate fibers and especially 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 outside 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 can be used to hold pins, brackets or the like (not shown) in order to be able to connect a plurality of 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, encloses a flame (not shown) of an oil burner or the like.
  • 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, slot-like recesses arranged on the plate elements 1 of the last section, which can be produced by appropriate depressions 7 ' (see FIG. 1) of the plate elements 1.
  • 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 gaps 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 used in 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 tilting and for stiffening the plate element 1 contribute.
  • One support bar 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, for. B. can be cut 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.
