Definitions
- the invention relates to a cylinder-piston unit, in particular for steam engines with expansion under the supply of heat according to the preamble of the main claim.
- a steam engine with a cylinder-piston unit according to the document DE-PS 828 988 with expansion under the supply of heat is previously known.
- the piston has a heat head insulated on the inside.
- the heat is supplied to the cylinder piston element via cylinder fins by means of an open burner in the stroke area of the insulated heat head and the cylinder head with the compression chamber. Steam is generated directly in the heated cylinder by metered water injection.
- the outlet for the expanded water vapor is formed by slots opened by the piston in the area of bottom dead center.
- Pore burners for essentially NOx-free combustion are known from the document DE 43 22 109 A1.
- a layering of parts which is varied from fuel gas inlet to outlet from fine to coarse-pore pores stabilizes and limits the temperature in the combustion process, thereby ensuring low-pollution combustion.
- This type of burner has a high power density based on its construction volume, an application as a hot water or steam generator is described.
- the object of the invention is to supply the cylinder-piston unit of the steam engine with heat directly at the cylinder head and expansion space by means of a pore burner.
- Pore burners work with relatively low firing temperatures and, due to their structure, enable the production of thermal bridges directly to the cylinder-piston unit.
- the low firing temperature level is suitable on the one hand for heat transfer to the working process of a steam engine with expansion under the addition of heat and on the other hand ensures low-pollution combustion.
- FIG. 1 shows a longitudinal section through a cylinder-piston unit with a
- Fig. 2 top view of a polygonal displacer shows a cross section through the cylinder-piston unit with an enlarged surface of the displacer and the warm cylinder section and the burning distances of the pore burner
- FIG. 1 shows a cylinder-piston unit 1 with a piston 2 and displacer 3 and an overall supply of heat to the working medium in the entire working space 5.
- a special pore burner 50 with the firing section A is used.
- Heat transfer paths B and C surround the lower part of the cylinder head 43 and the cylinder 1 in the stroke area 41 of the displacer 3.
- the guide piston 2 carries sealing rings 21 and a heat-insulated displacer 3. It is connected to a crankshaft via a connecting rod - not shown - and will be in the cylinder bore 4 in a warm and cold cylinder section 41; 46 out. - 3 -
- the displacer 3 preferably has an absorption or reflection surface 31, behind which there is preferably a heat storage layer 32 and an insulating layer 33.
- heat is stored on the one hand or heat is reflected on the other hand to heat the charge between the displacer 3 and the inner surface of the cylinder section 41.
- This design ensures corrective transfer of heat with high efficiency through the flow in the cylinder space and the warm walls of the cylinder section 41 and the cylinder head 43.
- radial ribs 44 and / or offset needle-like or web-shaped, radial projections are arranged on the cylinder jacket 42 in the cylinder section 41 of the displacer 3 or additionally on the cylinder head 43 .
- Heat transfer sections B and C of the pore burner 50 are formed between their sectors which are closed to the outside.
- Cylinder jacket 42 and cylinder head 43 can be designed as cast or sintered parts and / or a? to increase the heat transfer surface.
- the displacer 3 is guided in its stroke region with play parallel to the surrounding warm cylinder section 41 and has a cross section that becomes smaller in relation to the cylinder head 43.
- the mutually complementary surfaces can be made polygonal.
- the hottest heat transfer path B is assigned to this area.
- the warm cylinder section 41 in the stroke area of the displacer 3 and the cylinder head 43 are advantageously designed as radiators, the radiation of which lies in the range of the absorption spectrum of the working medium.
- the pore burner 50 is assigned to the cylinder head 43. It extends annularly over part of the cylinder head 43. Heat transfer sections B and C of the pore burner 50 and are expedient
- Steam generator 6 is surrounded on the outside by an insulating layer 51.
- the outside of the heat transfer paths C on the cylinder jacket 42 is enclosed by a steam generator 6 or preheater.
- the combustion gases of the pore burner 50 are removed from the space surrounding the steam generator 6.
- Pipe channels 7 of a superheater stage between the heat transfer paths B and C and / or in the cylinder jacket 42, preferably in its radial ribs 44 running parallel to the axis of the cylinder jacket 42, are advantageously arranged in a guided manner.
- the outlet channel 11 opens with windows that are overflowed by the sealing rings 21 of the guide piston 2.
