Definitions
- the invention relates to a heating system with electrical energy generation according to the preamble of patent claim 1.
- Heating systems with electric power generation are known and have already been described in numerous publications and patent applications.
- a boiler known.
- the boiler is equipped with a burner, a combustion chamber, a heat exchanger and an exhaust system.
- an externally heated heat engine is arranged in the combustion chamber of the boiler, which drives a power generator.
- the boiler can be a condensing boiler.
- the externally heated heat engine may be a Stirling engine with a closed system, the hot space of the fuel gases and the cold space is lapped by the combustion air to be supplied to the burner.
- a decentralized power supply by heat-power coupling with Stirling engine known.
- a combustion furnace for recovering thermal heat with a combustion chamber for combustion of the heating material and a heat exchanger for transmitting the heat to a heat transfer medium, preferably water, arranged to forward the heat to decentralized radiators.
- a heat transfer medium preferably water
- the primary heat exchanger surrounds the hot head of a Stirling engine.
- the primary heat exchanger is connected directly to the combustion chamber.
- the heating and power generation plant with a heating boiler for heating the building or for heating domestic water, with a burner for the boiler, a stirring motor which can be heated by the same burner, a generator and a heat pump.
- the Stirling engine is a free-piston Stirling engine
- the radiator can be connected heat transfer with a service water tank or with an air duct.
- the generator is a linear generator and coupled directly to the free-piston Stirling engine.
- the heat pump has an electric drive, which can be switched to mains operation, among other things.
- the linear generator can be electrically connected via a control with the drive motor of the heat pump, with the public power grid and with other consumers.
- Combined heat and power plants are based on the principle of combined heat and power; An internal combustion engine drives a generator that generates electricity. The resulting heat is supplied to the heating system via a heat exchanger.
- Common fossil fuels in combined heat and power plants are diesel, heating oil or gas. But renewable energy sources such as biogas, biodiesel, rapeseed oil and, more recently, wood pellets can also be used.
- the condensing technology can basically be used with any fuel. Currently, however, it has prevailed only in gas-fired plants, since the combustion of gas releases more water than oil or coal. Coal and oil have the disadvantage that when burned, the sulfur contained in the fuel attacks the boiler walls and the chimney and thus extremely reduces the life of the material.
- the invention is therefore based on the object; significantly increase the energy yield of known heating systems, so that a total active power of more than 150% is achieved, without affecting or even reducing the heating power of the mentioned heating systems. An increased energy consumption or pollutant emissions is excluded.
- the invention provides that the boiler of any heating system no longer heated directly from the combustion chamber is, but that the heat energy is supplied to the boiler via one or more displacement cylinder of a Stirling engine.
- This change ensures that the entire; heat energy generated in the combustion chamber; the boiler is supplied lossless, and that on the or the displacement cylinder, a Stirling engine is driven.
- the boiler also serves to absorb the heat energy and thus also to cool the working medium of the Stirling engine, in which the boiler is preferably set to a low-temperature heating system 40 ° to 60 ° C.
- the mechanical energy gained from the Stirling engine is usefully used to drive a power generator.
- FIG. 1 a section through a heating system according to the invention is shown, in which reference symbols for the identification of individual elements with numbers 1 to 17 are used as follows: - Combustion chamber, in which the heat energy by combustion for the
- Flywheel 10 transmits. 12 - displacement joint lever which transmits the force from the flywheel 10 to the displacement piston rod 13.
- the device according to the invention works as follows:
- the peculiarity of the heating system to be registered is that, in comparison with all hitherto known heating systems, a Stirling engine is integrated between a combustion chamber 1 and a heating boiler 4.
- the Stirling engine is powered on the one hand by the heat energy.
- the Stirling engine also conducts the heat energy unabated to the heating system (boiler 4).
- the Stirling engine thus has no influence on the heating power or on the energy consumption of the heating system (boiler 4) and also does not affect the pollutant emissions of the existing heating system.
- the displacement cylinder 2, the connecting line 7 and the working cylinder 8 are connected in a gastight manner with each other.
- the working medium is as a gas or a gas mixture such as air.
- the displacement piston 3 displaces the working medium past the displacement piston 3 into the high-temperature region of the displacement cylinder 2, the working medium expands through the heat absorption from the combustion chamber 1, thereby flowing past the displacement piston 3 via the connection line 7 into the working cylinder 8, thereby pushing the working piston 9 forward ,
- the displacement piston 3 displaces the working medium back into the low-temperature region of the displacement cylinder 2, where the working fluid delivers its thermal energy to the heating boiler 4.
- the working fluid is contracted again and by the resulting negative pressure of the working piston 9 is withdrawn.
- any heating system protrudes the high temperature range of one or more displacement cylinder 2 of a Stirling engine, so that the working medium there absorbs the heat energy, which is then supplied to the boiler 4 through the displacement piston 3.
- the boiler 4 extracts the heat energy from the working medium and thus lowers the temperature of the working medium to a preset low temperature value, which is preferably 40 ° to 60 ° C.
- the cooled working medium is supplied by the displacement piston 3 again the high temperature region of the displacement cylinder 2, where it absorbs heat energy again, so that the cycle described can be repeated up to 3000 times per minute.
- an additional electrical heating element 15 can surround the high-temperature region of the displacement cylinder or cylinders 2.
- the heating element 15, using the electricity obtained free of charge, serves to assist the generation of heat and thus significantly reduces the fuel supply to the heating system.
- the power is generated by means of a power generator 16, which is arranged together with the working cylinder 8 and the flywheel 10 in a housing 17 adjacent to the boiler 4. From the flywheel 10 is driven, for example by means of a belt drive of the power generator 16.
- Power generator 16 is thermally insulated by insulation 14 to the outside.
- the said devices are in heat exchange with each other. Therefore, the frictional heat generated by the stirling engine and the power generator 16 can not escape through the insulation 14 and is stored in the housing 17. By the connection of the housing 17 to the boiler 4, this heat energy can be additionally absorbed by the boiler 4. This additional heating energy is supplied to the heating system.
- the insulation 14 of the device also serves as sound insulation.
