    The invention relates to a heating device with a combustion chamber for combustion of biomass-based fuel, as stated in claim 1
    A large number of heating devices are known from the prior art, which pursue the goal of earning the highest possible thermal efficiency. Especially in central heating appliances to increase the cost of fossil, liquid or gaseous fuels, a plurality of technical measures are known with which the temperature of the flue gas can be kept relatively low when passing into a fireplace or the heat energy withdrawn from the flue gas is relatively high provided another heat exchanger, in which the flue gas is passed through a plurality of horizontally or spirally extending flues, so that the highest possible proportion of the heat energy contained in a heat transfer medium, usually water, is discharged. Such heat exchangers are well suited in the combustion of liquid or gaseous fuels, after only very small amounts of combustion residues, in particular soot or ash occur. In heaters to more expensive solid fuels, especially biomass in the form of wood or pellets, these prior art designs of heat exchangers are not very satisfactory. In addition, these voribekannten constructions for integration into heaters, which are to be set up directly in a living room, especially in conjunction with so-called stoves, only partially suitable.
    The present invention has for its object to provide a heater which has increased functionality or multiple functionality, so that among other things, the operating comfort and efficiency can be increased. In particular, a heating device for direct installation in residential areas is to be created, which, in addition to increased ease of use and / or ease of use, also offers the highest possible degree of efficiency with regard to the heat energy provided.

    This object of the invention is achieved by a heating device with the features of claim 1.
    An advantage of the measures according to the invention lies in the fact that despite the compact construction of the heating device, a high degree of efficiency is achieved with respect to the heat energy provided by the heating device and used to heat the ambient air. In particular, when the channel sections to form the flue gas ducts of the heat exchanger in the vertical direction almost over the entire height, in particular about up to 70 to 90% of the overall height of the heater extend, a relatively high proportion of the heat energy contained in the flue gas withdrawn and be transferred by heat transfer directly to the ambient air. By the at least two vertically aligned, juxtaposed and thereby fluidly connected in series channel sections a relatively long flow path for the flue gas is constructed, so that an intense heat transfer is ensured on the preferably metallic wall sections of the correspondingly constructed heat exchanger. The vertical arrangement and series connection of the individual, juxtaposed channel sections results in an optimized overall ratio between required space or space requirement and the ultimately erzietoaren, thermal efficiency. The U-shape or meandering shape of the flue gas duct fm heat exchanger, wherein the legs of the U- or meandering channel sections are aligned vertically or vertically, also harbors purejgungstechnlsche advantages, since combustion particles or Russtelle accumulate primarily in the bottom region of the heat exchanger and thereby a concentrated, collected removal of any soot or combustion particles is possible. In contrast to a horizontal course of flue gas ducts so is the Reinlgungsfähfgkeft or the maintainability of the specified heat exchanger of the heater comparatively low. Another advantage of the embodiment of the invention is that the inlet for the flue gas are formed in the heat exchanger and the outlet for the flue gas from the heat exchanger in each case in the upper end portion of the heater, so that any contamination of the environment when completing a used heater from a dwelling-side chimney are minimized. In particular, by the arrangement of the flue gas outlet in the upper end portion of the heater, the probability or the risk of contamination of the environment when completing the heater of a flue pipe or a corresponding fireplace is comparatively low. In addition, the predominantly vertical course of the channel sections favors the cleaning of the vertical smoke.

    - 3 - gas trains in the heat exchanger with a broom or with suction devices, as the gravitational effect on the soot or combustion articles favors their cleaning or discharge or supported.
    Also advantageous are the measures according to claim 2, since characterized the flue gas blower is positioned in a thermally favorable, especially in a relatively cool section of the heater. The technical requirements of the flue gas blower and its thermal load are thus as low as possible, which set among other benefits in terms of efficiency or Entlezuverldssigkeit.
    Another advantage is that the Rauchgasgebfäse itself, in particular its Luftführungs- or connecting portions can form at least part of the connection or transfer channel between fluidically immediately consecutive vertical Kanalabschnftten. The number of additionally required components is thereby kept as low as possible or thereby fulfill the already required or existing Luftfqhrungskanäle or end sections of the flue gas blower at the same time the function of a Strömungsverblndung between successive channel sections to be shaded in series. An essential advantage of this design is also the fact that the flue gas blower is ausgebiidet in the bottom portion of the channel sections and in this bottom-side section gradually or increasingly accumulating soot particles or VerbrennungsrQckstände by the relatively high suppression or top pressure of the flue gas blower due to the vicinity of the Flue gas blower optimally transported or weftergefördert. That is, accumulations of soot particles in the bottom portion of the vertical channel portions are minimized by the placement of the smoke gas blower in this bottom end portion. In particular, the flue gas blower has its greatest flow-technical performance in its immediate vicinity or Arschlussbereich, so that the tendency to particle or Rußansammlungen in the bottom area or in the lower end portion of the heat exchanger is clearly lagged.
    Also advantageous are the measures according to claim 3, since thereby the entire back or rear wall of the heater and thus the rear wall of the combustion chamber can be used for the arrangement or attachment of the heat exchanger. In particular, this achieves an intensive transfer of heat from the flue gas to the ambient air of the heating device. A further advantage is that the corresponding channel sections or the heat exchanger formed therewith have technical aspects with regard to Wiring-N2011 / 06400 14/03 2011 MO 16:37 [SE / EM NR 9673] @ 007 16:41:10 14-03-2011 β / 39 25 16:41:10 14-03-2011 β / 39 25 • · · 4 * · * · ** < Increased kunggrader can be increased, in particular a plurality of distributed heat dissipation webs may have. Due to the back placement of these channel sections while no design or optical impairments are caused after the heat exchanger is assigned by the rear mounting on the furnace housing mostly wall sections and the heat exchanger is hardly or not visible by a user. This means that as a result the heat exchanger can be particularly optimally designed with regard to the thermal efficiency and, due to the customary assignment to a wall in the respective living area, no impairment of the visual appearance of the heating device occurs. In addition, it is also possible for marked or relatively sharp-edged projections to be formed on the surface of the heat exchanger. By nearest-lying, direct assignment to a wall in a living space to be heated, these projections are not or difficult to access, so that the risk of injury is highly unlikely or no additional cladding elements for example knob-like or web-like projections on the surface of the appropriate heat exchanger are required. Also, the manufacturing cost can be reduced thereby, whereby the efficiency of the specified heater is increased.
    The measures according to claim 4 are also advantageous, since a part of the boundary surfaces or boundary walls of the heat exchanger is defined or formed by partial sections of the metallic furnace housing. As a result, the total required material requirement for the corresponding heating device can be kept as low as possible, thereby achieving economic advantages can be. In addition, this can keep the total weight of the heater low. In addition, the highest possible heat transfer from the flue gas to the metallic sections or components of the Heizefnrichtung or the heat exchanger is achieved, so that the flue gas as much heat energy is withdrawn. In addition, the metallic channel sections or the Metaüprofiie used for stiffening the furnace housing graze used, so that the metallic support structure of the furnace housing may have a relatively low rigidity, after the furnace housing in conjunction with the metal profiles to create the heat exchanger in its rigidity or stability positive being affected. This also allows better account to be taken of high economic and energy-related requirements. N2011 / 06400 14/03 2011 MO 16:37 [SE / EM NR 9673] @ 008 25 16:41:29 14-03-2011 9/39

    Another advantage is the development according to claim 5, since thereby also represent greater manufacturing tolerances no problems in terms of the required gas-tightness of the heat exchanger, whereby the efficiency of the heater is further favored. In addition, thermal expansion and consequent stresses can not lead to leaks of the heat exchanger by these measures, so that a particularly high reliability and reliability is guaranteed. In addition, by the connection of the metal profiles with the corresponding wall sections of the heater, in particular by the mechanical connection with the rear wall of the furnace housing, the overall achievable rigidity or dimensional stability of the furnace housing favors.
    Another advantage are the measures according to claim 6, as this spatially relatively complex metal profiles can be produced as economically as possible. In addition, such cast iron metal profits provide optimized heat transfer capability. In addition, such, one-piece metal profiles made of cast iron can take on a variety of desirable or required functions or fulfill, whereby the variety of parts can be kept within limits.
    But also advantageous are the measures according to claim 7, as this creates an enlarged heat transfer surface, without thereby increasing the required volume of the heat exchanger. In particular, a relatively intensive heat transfer is achieved starting from the hot flue gas on the metallic boundary surfaces of the heat exchanger.
    However, the measures according to claim 8 are also advantageous, since this ensures the most intense possible heat transfer from the metallic surfaces of the heat exchanger to the ambient air surrounding them. In particular, the heat transfer capacity of the heat exchanger can be increased in a simple manner.
    Another advantage is the weiterbiidenden measures according to claim 9, since thereby a quasi-turbulent turbulence of the ambient air takes place and thus an intense heat transfer from the surface of the heat exchanger to the ambient air can be achieved In particular, the thermal convection by rising upward, increasingly warming ambient air The baffled projections are deflected or swirled so that the heat transfer capacity is increased from the 142011/06400 14/03 2011 MO 16:37 ISE / EM NR 9673] 0009 25 • * 16:41:46 14-03-2011 10/39 • «· · · ································································································································································································································································
    Also advantageous are the measures according to claim 10, as this almost the entire hzw. a relatively far reaching height of the heater is utilized to escape the hot flue gas as much heat energy. In addition, an improved cleanliness is achieved when completing and re-connecting the heater to a chimney or a flue gas pipe. In addition, this makes it possible to place the heater as close as possible to the boundary wall of a room can, without difficulty with respect to the integration into a flue of a chimney occur.
    Furthermore, the measures according to claim 11 are advantageous, since the most economical construction is created after sections of the flue gas blower can perform as sections of Oberieitungs- or connecting channel between the vertically extending channel section. In addition, a sufficiently stable or sufficiently rapid flue gas flow is achieved in the flue gas channel and thus ensures optimized combustion of the fuel. Of particular advantage is further that thereby accumulations of soot or combustion residues kn lower end portion or avoided in the bottom portion of the heat exchanger or be kept behind, after the flue gas blower positioned there prevents larger accumulations or clusters as much as possible. In particular, the flow conditions in the bottom section of the heat exchanger are such that gradual accumulations can be avoided or accumulated particles can be continuously removed.
    This is especially true when the flue gas blower is switched to increased delivery or flow capacity in the short term. In particular, this can be used to create a need-based, periodic or otherwise controlled cleaning of the heat exchanger. The efficiency of the heat exchangers can thus be kept relatively high or in an optimal range over a longer period of time.
    Also advantageous are the measures according to claim 12, since thereby the rising in the combustion chamber flue gases are derived only from the upper end portion of the combustion chamber, whereby a sufficient residence time is present in order to transfer the heat energy to the wall sections and the top surface of the heater can. It also reduces the likelihood of fluidized combustion residues or fuel components getting into the heat exchanger / 39 • ··· ······················································································································································································································ increased level. In particular, contaminants of the heat exchanger are kept as low as possible by the passage of flue gas into the flue of the heat exchanger, starting from the upper end portion of the combustion chamber.
    Also advantageous are the measures according to claim 13, since in a simple manner an air duct between the channel sections or metal profiles of the heat exchanger is formed, which favors the heat transfer to the ambient air or the heat extraction from the metallic surfaces of the heat exchanger. In addition, the convection effect is exploited in order to achieve the most intensive possible transfer of heat energy from the heat exchanger surfaces to the ambient or room air.
    A particularly advantageous embodiment of the heating device is specified in claim 14. Such a heater meets high comfort requirements to a high degree. In particular, a largely automated or long-term autonomous operation of the heater can be ensured if the heater is operated with automatically supplied pellets. In particular, optimal combustion and utilization of the available biomass is thereby achievable, provided that corresponding control technology control or monitoring systems are used. A particular advantage of this design is also that it can be heated if necessary or on request also with firewood, in particular, an addition of firewood is also possible as an alternative or in addition to the combustion of pellets. As a result, on the one hand, economic aspects can be better taken into account or, as a result, end-user-prone wood products in the heating device can be burned as needed. In addition, by the Scheithoizbe-drive thermal combustion or a good heating performance can be achieved without an electrical power supply for the heater is required. Even with power outages so an operation of the specified heater with manually feedable biomass, especially with pieces of wood or logs is possible. The corresponding heating device can thus be operated simultaneously or optionally with two different fuel materials, in particular with pellets and / or firewood, which on the one hand high demands on the ease of use and other high economic aspects is taken into account. In addition, in the event of a surprise occurrence of the stock of a particular genus N2011 / 06400 14/03 2011 MO 16:37 [SE / EM NO 9673] © 011 25 16:42:23 14-03-2011 12/39 * * « * • · • · »·

    Fuel, for example, the pellets are easily heated with the optionally still available or available Brennmateriaitype.
    Also advantageous are the measures according to claim 15, since a combinatorial or alternately combustion of pellets and firewood is optimized in a simple manner, in particular the combustion chamber base plate is suitable for storing or supporting a sufficient amount of firewood to be burned, While in the lower, relatively small-volume combustion chamber trough an optimal combustion of supplied pellets is guaranteed. In addition, the lower-lying arrangement of pellets supports a combined combustion of pellets and firewood or, as a result, the combustion or increase in price of pellets can be used for the simple lighting or firing of firewood. As a result, increased comfort requirements are met or thereby lighting the firewood is much easier
    Of particular advantage is also the development according to claim 16, since in the area of the pellet combustion bowl an additional firewood overlay is created, so that inserted into the combustion chamber firewood can not completely cover the pellet burner or combustion chamber trough, causing the combustion the pellets or the combustion air flow required for igniting and burning the billets is not hindered. In particular, thereby a staking of the pellets in the combustion chamber Muide is kept behind, after a sufficient supply of combustion air below the billets and on the top of optionally located in the combustion chamber Muide pellets remains guaranteed. In addition, the rams within the combustion chamber trough can thereby wall up on the firewood, which favors the ignition and burning of firewood.
    Also advantageous are the measures according to claim 17, as this firewood can be placed transversely or longitudinally over the combustion chamber trough and a large or sufficiently intense flow around with combustion air is ensured. In addition, this ensures a good flame of the pieces of chopped firewood and thus favors optimal combustion or as low as possible combustion of firewood.
    Finally, the measures according to claim 16 are also advantageous, since this ensures an intensive re-circulation of the billet with combustion air. In addition, even when logs are placed tightly over the combustion chamber depression, a sufficient amount of N2011 / 06400 14/03 2011 MO 16:37 [ SE / EM NR 9673) @ 012 25 16:42:41 14-03-2011 13/39 • • * • «· · · · · · • · · · · · · · · · The supply of combustible pellets, which may be present in the combustion chamber cavity, can be ensured with combustion air.
