Definitions

  • the invention relates to a combustion device, in particular for wood waste, logs and the like, consisting of a fuel receiving space, a feed for the combustion air, an exhaust pipe and a device for igniting the fuel supply.
  • combustion devices of this type which are used, for example, in wood-processing companies for heating and / or hot water preparation, there is the difficulty of ensuring that combustion is flawless and satisfies the requirements of environmental protection.
  • a satisfactory work of such combustion devices could previously only be achieved if a corresponding design and control engineering effort was taken, which in many cases, however, cannot be accepted for cost reasons.
  • the object of the present invention is to design a combustion device of the type specified at the outset in such a way that, despite a simple and therefore economically feasible construction of the device, optimum combustion conditions are ensured throughout the entire burn time and thus a largely residue-free combustion is obtained, without that complex control devices are required.
  • the fuel receiving space consists of an upright container with at least essentially all-over perforated wall, the bottom area of which is tapered, that the combustion air via a gap enclosing the container on all sides and delimited radially inside by the container wall is supplied against the direction of flame propagation that the exhaust gases in at least one of the gap space surrounding flue gas duct are guided to a flue gas outlet, and that the device for igniting the fuel supply is arranged in the region of the tapered lower end of the container.
  • the output control of the combustion device takes place via the fuel supply, and the refilling processes can also be carried out automatically or by using a suitable additional device.
  • the container intended to hold the fuel supply is preferably cylindrical and tapered in the shape of a truncated cone at its lower end region.
  • This tapering of the container which is synonymous with a reduction in volume in this area, has the particular advantage that, due to the smaller amount of fuel in this area compared to the upper part of the tank, the ignition process is made considerably easier and surprisingly fast ignition is achieved with a minimum of carbonization gas .
  • This comparatively small-volume lower end region of the container forms a zone of very high temperature during the entire combustion process, to which all the exhaust gases are guided past due to the special guidance of the combustion air, irrespective of the place where they occur, and thus the components that have not yet been completely burnt are subjected to inevitable post-combustion.
  • the container holding the fuel supply is preferably made of perforated sheet metal, so that, in the sense of the task, this component, which is essential for the function of the overall device, can be obtained in a particularly economical manner.
  • the gap space carrying the combustion air is delimited radially on the outside by a sheet metal jacket adapted to the shape of the container and is connected to a blower.
  • a pressure blower and a suction blower can be used, but it is particularly advantageous to connect a suction blower to the gap space via the flue gas outlet, since in this way a particularly uniform flow of combustion air around the container is achieved and it is also ensured that If you open the lid of the fuel tank or if there are any leaks, there is no risk of smoke gases escaping immediately.
  • the container used to hold the fuel is preferably removable and exchangeable so that, if necessary, problem-free replacement of this container is possible without the help of specialists.
  • the fuel supply is ignited by means of a hot gas source.
  • a hot gas source This is done by an oil or gas burner Hot gas is directed via a pipeline opening directly adjacent to the lower end of the container against the fuel supply located in the container, with a practically smoldering gas-free ignition being obtained within a very short time.
  • the blower of the oil or gas burner can also be switched on and off independently of the burner ignition, so that this blower, when the combustion device is already in operation, can also be used to supply additional combustion air into the hot area at the lower end of the container and thus the afterburning taking place there to favor.
  • the use of suitable air baffles leads the combustion air with swirl through the gap space.
  • These air guiding elements can be provided in the area of the air inlet openings, which are arranged in the upper end cover or in the ring area assigned to the gap, or in the lower area of the gap 3.
  • baffle plates suitably arranged in the flue gas passages concentric to the fuel container can be provided.
  • each flue gas flue can be surrounded by a water jacket or overall insulation can be used, in which case a heat exchanger will be connected downstream of the combustion device.
  • the entire combustion device can be designed as a sheet metal construction and optimal burn-off is also ensured without complex and special control devices, the overall result is an extremely economical and easy-to-use arrangement.
  • a cylindrical container 1 made of perforated sheet metal with a conically tapering lower end 2 is used to hold the fuel supply.
  • This container 1 which can also be referred to as a firing insert, is surrounded by a sheet metal jacket 4 ′ which is adapted in its shape to the container 1, so that a gap 3 is formed between the container 1 and this sheet metal jacket 4, to which the combustion air is supplied.
  • the combustion air is supplied via openings 5 formed in a central part, with the aid of a blower not shown in the drawing.
  • the sheet metal jacket 4 extends into the area of the lower end of the container 1, so that the combustion air and the resulting exhaust gases are always from top to bottom and to this area, which always forms the hottest point in operation, and only then be deflected and passed into the flue gas duct 6, which is delimited by an outer jacket 7 and concentrically surrounds the container 1 and the gap 3.
  • a flue gas outlet 8 is provided in the area of the upper end of the flue gas flue 6.
  • the flue gas flue and thus the entire combustion device are surrounded by a water jacket 9 of the usual type.
  • the fuel supply is ignited by means of hot gases supplied via a pipe socket 11, which is directed directly against the comparatively small amount of fuel in the bottom region 10 of the container 1.
  • This hot gas for example, which has a temperature of about 1200 ° C., is generated by means of an oil or gas burner connected to the pipe socket 11 and causes the fuel to ignite very quickly, which takes only a few seconds, with no annoying carbonization gas formation due to the small material supply in the ignition area occurs.
  • the small amount of ash produced is collected in a drawer 12 arranged below the burning insert.
  • the slipping of the fuel supply during the combustion process is promoted by the shape of the container 1 described.
  • baffle plates 13 can be arranged in the flue gas flue.
  • the combustion air is guided in a swirling manner through the gap space 3, which can be achieved by means of suitable air baffles.
  • Baffles 14 of this type can be formed directly on the cover part and can be realized in a practically simple manner by means of tabs pressed inwards, the resultant plates being produced in the process openings simultaneously form the air inlet openings.
  • the embodiment shown in Fig. 2 differs from the combustion device described so far essentially in that instead of a flue gas flue with a flue gas flue at the top, two flue gas flues 6, 16 arranged concentrically to one another and in opposite directions are provided, in which case the flue gas flue 8 in the bottom Area of the combustion device is located.
  • the flue gas flues 6, 16 are connected to one another in the region of their upper end via passages 15 and each surrounded by a water jacket 17, 18.
  • this automatic fuel supply can be implemented without difficulty, it being possible to work with a double flap arrangement or a cellular wheel sluice for safety reasons.
