Definitions
- the invention relates to a burner, in particular for heating systems, with a housing which receives a pore burner and forms an exhaust gas chamber towards the exhaust gas outlet, in which the housing itself is designed as a heat exchanger and with an inlet for a gas leading to the inflow side of the pore burner -Air mixture is provided as fuel.
- Such a burner is known from DE 195 27 583 C2.
- the housing is designed as a hollow cylinder and receives a cylindrical pore burner.
- the pore burner is supplied with the gas-air mixture over a large area as fuel on one end face via a distribution chamber and a porous burner plate.
- the exhaust gas space with the exhaust gas outlet connects to the free end face of the pore burner.
- the housing is a pore burner and closed to the exhaust gas space and even designed as a heat exchanger with channels for the liquid to be heated.
- the efficiency of this heat exchanger is primarily designed for the increased radiation energy of the pore burner.
- the exhaust gases sweep along only part of the inner wall of the heat exchanger, so that its thermal energy is not used optimally.
- This object is achieved according to the invention in that at least the sides of the pore burner adjoining the inflow side are enclosed by a part of the housing which is designed as a radiation heat exchanger in that the part of the housing which forms the combustion chamber for exhaust gas emission has a convection -Heats exchanger or is itself designed as such and that radiation and convection heat exchangers are flowed through by the liquid to be heated.
- the housing comprises two areas which can be optimally designed as a radiation heat exchanger and as a convection heat exchanger. Since the first housing part encloses a substantial part of the pore burner, the radiation energy acts on it optimally and contributes to increasing the efficiency, just like the second housing part, which is itself designed as a convection heat exchanger or receives one. This allows the efficiency of the burner to be increased considerably overall, since both the radiation energy and the thermal energy of the exhaust gases can be optimally implemented. There are numerous design options for realizing the burner according to the invention.
- the pore burner is cylindrical and a sleeve-shaped housing part encloses at least the outer surface of the pore burner as a radiation heat exchanger.
- This housing part can rest against the pore burner or be arranged at a short distance from the pore burner.
- the pore burner is designed as a hollow cylinder and a part of the housing at least encloses the inner and outer surface of the pore burner as a radiation heat exchanger, then the radiating outer surface of the pore burner is considerable with a slightly increased size of the burner elevated.
- a part of the housing that forms the convection heat exchanger is connected to the part of the housing that is designed as a convection heat exchanger and is provided with the exhaust gas outlet or that is located on the housing part , which forms the radiation heat exchanger, connects a receiving part, which receives a separate convection heat exchanger and is provided with the exhaust gas outlet.
- this convection heat exchanger is included in the exhaust gas flow and increases the efficiency.
- the housing expenditure can be kept small on the one hand in that the housing part forming the radiation heat exchanger and the housing part forming the convection heat exchanger are designed as a one-piece cast housing and on the other hand in that the housing part forming the radiation heat exchanger and the separate convection -Heat exchanger receiving housing part are designed as a one-piece cast housing.
- the burner process can be stabilized in that the inflow side of the pore burner is covered by a porous burner plate which serves as a backstop and is adapted to the shape of the inflow side and to which the gas-air mixture can be supplied as fuel via a correspondingly shaped distribution chamber.
- the proportion of the pollutants contained in the exhaust gas can be influenced by covering the peripheral surface of the burner plate and part of the subsequent jacket surface (s) of the pore burner by means of partial insulation.
- the closed surface facing the pore burner of the housing part forming the radiation heat exchanger is smooth or provided with ribs in order to offer the radiation a large surface.
- the housing part forming the radiation heat exchanger can also be designed as a separate part with channels for the liquid to be heated.
- FIG. 1 shows a burner with a hollow cylindrical convection heat exchanger, to the jacket of which a radially connected heat exchanger with a cylindrical pore burner is connected,
- FIG. 2 shows a burner with a hollow cylindrical pore burner in an annular and trough-shaped radiation heat exchanger, to which an exhaust gas chamber with inserted, separate convection heat exchanger connects
- Fig. 3 shows a burner with a cylindrical pore burner in a sleeve-shaped radiant heat exchanger which is connected to a housing part which accommodates a separate convection heat exchanger
- Fig. 4 shows a burner with a hollow cylindrical housing, which is designed in a section as a radiation heat exchanger and receives the pore burner and in a further section limits the exhaust gas space and is designed as a convection heat exchanger.
- a gas-air mixture G + L is used as fuel via a distributor chamber 12 and a porous burner plate 11
- a pore burner 10 can be constructed in a known manner as a wire mesh, as a porous ceramic body and the like; it is preferably used in the burners due to its high radiation energy.
- the cylindrical pore burner 10 is accommodated in a lateral, sleeve-shaped housing part 30 of the housing 20 designed as a one-piece cast housing.
- the housing part 30 can rest against the outer surface of the pore burner 10 or enclose it at a small distance, in the housing part 30 of the housing 20 channels are introduced through which the liquid KF to be heated flows.
- the part 30 of the housing 20 thus forms a radiation heat exchanger.
- the housing part 30 of the housing 20 merges in one piece into the hollow cylindrical housing part 40, which has ribs or the like on the inner wall wearing.
- This housing part 40 of the housing 20 also has channels or cavities through which the liquid KF to be heated flows, like the housing part 30, and has an outlet 18 for condensate K collecting in the housing part 40 of the housing 20.
- the exhaust gas leaves the exhaust gas space formed by the housing part 40 of the housing 20 through the exhaust gas outlet AG.
- the housing part 40 of the housing 20, as a convection heat exchanger is optimally adapted to the heat energy which can be removed from the exhaust gas, so that overall, in the burner according to FIG. 1, increased efficiency can be achieved over a wide output range of the burner.
- the design of the burner remains very simple, especially with regard to the design of the radiation and convection heat exchangers.
- the pore burner 10 can also be designed as a hollow cylinder.
- the housing part 30 of the housing 20 then covers the inner and outer lateral surface of the pore burner 10 in a trough-shaped and ring-shaped manner.
- the gas-air mixture G + L is supplied via an annular disk-shaped distributor chamber 12 and an annular disk-shaped, porous burner plate 11 onto the ent - Talking shaped inflow side of the pore burner 10.
- a housing part 45 of the housing 20 forms a receptacle for a separate convection heat exchanger 50, through which the exhaust gas flowing from the exhaust gas space of the housing 20 to the exhaust gas outlet AG passes and releases its thermal energy to the medium flowing through the convection heat exchanger 50.
- the housing parts 30 and 45 form a one-piece housing 20 which, for. B. can be formed as a cast housing.
- the liquid KF to be heated flows through both heat exchangers, which can be connected in series and / or in parallel in terms of flow.
- the cylindrical pore burner 10 is inserted into a sleeve-shaped housing part 30 of the housing 20. drove the gas-air mixture G + L again via a distribution chamber 12 and a porous burner plate 1 1. Part of the lateral surface of the pore burner 10 adjoining the burner plate 11 is covered with partial insulation 13. The proportion of pollutants contained in the exhaust gas can thus be influenced, in particular reduced.
- the housing part 30 of the housing 20 is connected to a further housing part 45, which receives a separate convection heat exchanger 50, via which the exhaust gas reaches the exhaust gas outlet AG.
- the housing part 45 forms part of the exhaust space and is with the
- the burner according to FIG. 4 differs from the burner according to FIG. 3 in that the housing part 30 of the housing 20, which forms the radiation heat exchanger, merges directly into the housing part 40 of the housing 20, which encloses the exhaust gas space and as a convection heat exchanger trained and provided with the exhaust outlet AG.
- Both heat exchangers are formed by the one-piece housing 20 and the liquid KF to be heated flows through.
- the inner walls of the housing 20 can in the region of the housing part 40, i. H. of the convection heat exchanger can be provided with ribs or the like to enlarge the area.
