Definitions
- Patent application Small combustion plant with installation
- the application relates to a small combustion plant with installation.
- Small combustion plants are one of the main sources of emissions for particulate and numerous gaseous emissions, such as CO, VOC and PAH, which have a significant impact on human health.
- gases are formed by incomplete combustion due to non-optimal oxidation conditions (local oxygen, active residence time and temperature). Due to the complicated process of combustion of solid fuels, the fulfillment of the oxidation conditions is only possible through sophisticated, well-designed combustion technology with intelligent control.
- non-catalytic emission control systems A number of non-catalytic emission control systems have also been developed.
- the non-catalytic exhaust gas purification systems which are to be installed in the small combustion plant or in the connecting piece, are usually based on the principle of the storage filter.
- a foam structure is used, which can also be catalytically coated.
- the dust-like pollutants are to be separated and burnt free upon reaching favorable temperatures.
- the inorganic components remain in the foam structure, which from time to time due to the increase of the
- the apparatus comprises a housing with bottom and lid.
- a catalyst device is present, which has a catalytic material. This is a ceramic with which oxidation of the exhaust gases can be catalyzed.
- the catalyst device has a plurality of openings, which are separated from the exhaust gases
- the bottom of the apparatus has an opening through which exhaust gas from the small furnace can be fed into the apparatus and the lid has an opening through which the treated exhaust gas can be discharged.
- Combustion chamber and heat exchanger contains a suction duct and a chimney.
- a fine dust filter with renewable profiled filter medium for the separation of coarse, fine and / or fine dust is provided as a filtering separator. This reduces particulate emissions.
- DE 29 27 725 A1 discloses a method and a device for preventing condensation, in particular for heating chimneys. This is a connection between existing in the environment of the boiler warm air atmosphere and the
- Fresh air supply provided.
- a mixture of dry, externally supplied hot gas with the chimney gas mixture is to be made by means of a mixing device and passed into the chimney area and passed through the chimney for drying.
- the mixture is intended to be produced essentially in the entire peripheral region of the exhaust pipe.
- the warm externally supplied gas may be, in particular, room air.
- the object of the invention is to provide a small combustion plant, which enables low-emission operation with the least possible effort.
- the mixing should generally be fine. Usually a mixing with a
- the heat capacity of the installation is one
- the installation can thus fulfill two functions at the same time, which improve the combustion.
- Combustion has been heated accordingly, that is, that sufficient energy has been stored in the form of heat for the oxidation. But this is usually guaranteed. Except at the beginning of the combustion operation, the combustion power is usually sufficient to achieve this. In addition, the incineration usually takes place in part anyway in the installation. The installation thus causes an increased constancy of the temperature, ie a homogeneous temperature distribution or a homogeneous temperature field. The avoidance of undershooting of the minimum temperature leads to improved combustion. This has two main advantages. On the one hand this reduces unwanted exhaust emissions. On the other hand, the combustion efficiency increases. Because of the improved Incineration, so the improved oxidation, the installation can also be regarded as an oxidation module. Because of the heat storage properties, a designation as a high-temperature storage module is also suitable.
- the heat conduction and heat transfer must be high enough so that the heat can enter the installation sufficiently quickly and, especially when needed quickly enough removed from the installation and for the oxidation reactions can be provided.
- the structure is not only improved mixing of combustible
- the installation leads rather to an increase in performance.
- the installation is therefore also for the user itself an advantage, in any case, it is not a disadvantage.
- a reduction in the performance of the small combustion system is connected. This leads to the temptation to bypass the installation or remove again.
- the elimination of this temptation is an advantage of the present installation, as it can be assumed that the achievable reduction of emissions actually is reached.
- the installation can be made inaccessible, whereby the manipulability is limited. Since the cross-section is not significantly reduced when using the installation, no bypass or no Anatomklappe is necessary. This facilitates the construction and in turn avoids manipulation possibilities.
- the improved thermal oxidation achieved by the installation is not subject to aging and is not damaged by undesired exhaust gas components, such as sulfur dioxide, heavy metals and fine dusts, including chloride and potassium salts, as can occur in the catalytic process, since these exhaust gas components often lead to poisoning of the catalyst ,
- the installation causes an enlargement of the
- Reaction zone so it will increase the volume in which the oxidation takes place. Because it is an active reaction, it is often referred to as an active reaction zone.
- the increase in volume is due to the above-described effects of better mixing of combustible exhaust components with combustion air, so mostly by a
- combustion can be better overall.
- the installation is not only easy and inexpensive to implement, the disposal is usually easy.
- the installation is constructed of a plurality of elements.
- the installation is usually easy to retrofit anyway. This is especially true for installation of a plurality of elements.
- Uniform or different elements can be combined.
- the elements can be connected deterministic or non-deterministic, systematic or non-systematic, structured or not structured.
- the elements can be connected transversely for better function. This can be advantageous for the later-described heat conduction within the installation, but also serve a better mechanical stability.
- the installation is formed by one or more modules of cast material.
- a module made of cast material can be produced comparatively easily. Within such a module, the heat can often be well transported since possible thermal resistances are eliminated in the transition from one element to an adjacent element. As a rule, it should be beneficial to provide a single module.
- An installation can also be constructed of several modules.
- the elements of the installation are Pall rings.
- a Pall ring is a hollow cylinder with blades pointing inwards. Outside are usually holes. The blades and holes give the impression that the blades are formed, as it were, from the wall of the hollow cylinder bent inwards at the points of the holes.
- Such Pall rings are commercially available and can be assembled into an installation having the above-described characteristics and advantages.
- the elements of the installation metallic and / or ceramic and / or stony components or combination of the two are crucial that the elements can withstand the high temperatures. Therefore, the selection will very often fall on ceramic or stony components, since ceramic components, including components of other types than the components described herein, have been proven in small combustion systems.
- Pall rings are available from ceramics. With the Pall rings as elements can. In general, materials can be used which have already proven themselves in many industrial applications.
- the incorporation may include microturbulence in the
- the installation has thermal conduction properties that are suitable for compensating temperature differences within the installation. With that you can Local temperature falls are avoided, since the heat can flow away quickly enough from the areas in which the temperature is high enough, that even with a heat flow, the minimum temperature does not fall below.
- the heat conduction properties of the installation depend on the one hand on the heat conduction of the material used. Especially with a built-up elements it is also necessary to ensure a thermally good contact between the elements.
- the mounting has surfaces with adhesive
- the installation causes a multiple deflection of combustion air and / or exhaust gas. This can be achieved, for example, by arranging a multiplicity of Pall rings. But other installations can cause this.
- a multiple deflection of combustion air and / or exhaust gas can be achieved, for example, by arranging a multiplicity of Pall rings. But other installations can cause this.
- Redirection of the combustion air and / or the exhaust gas leads to an improved mixture of combustible exhaust components and combustion air and thus to lower emissions and higher combustion efficiency. Above all, the combustion is improved by the increased residence time.

- FIG. 2 shows a plan view of the installation according to FIG. 1.
- the elements used are ceramic Pall rings with a diameter of 50 mm and a thickness of 0.8 mm.
- the used ceramic is available and durable. It is expected to have a lifetime of more than 1 5 years.
- the ceramic has proven to be very robust against unfavorable fuels such as wet wood and waste as well as against harsh operating phases and instation of combustion such. B. proven in the start-up phase.
- the installation used should have a very rough surface and have mini-turbulators, which are distributed horizontally (or transversely to the exhaust gas flow) in the entire installation cross-section at different heights.
