Definitions
- the invention relates to a device for generating electrical or mechanical energy with a combustion device for a solid, gaseous or liquid medium, in particular biomass, which generates flue gas which contains heat during combustion, and with an RC system, in particular an ORC Plant, which has a circuit for a working medium, which is guided for the absorption of heat by acting as a working medium evaporator heat exchanger.
- Such a device according to the invention for power generation is described both in the German utility model application DE 20 201 1 001 1 1 1.9 with the utility model DE 20 201 1 001 1 1 U1 and in the German utility model application DE 20 2010 017 143.1 with the utility model DE 20 2010 017 143 U1, which are hereby incorporated by reference and whose disclosures are fully incorporated in the description of this invention.
- a combustion device is a system in which by the supply of air, a solid, liquid or gaseous medium is oxidized as fuel and thereby exhaust gases in the form of gaseous combustion products. Due to the chemical energy stored in the fuel, heat is released in the oxidation of the fuel.
- the gaseous combustion products formed during combustion are referred to herein as flue gas.
- the temperature of this flue gas can be up to 1000 ° C or even higher.
- ORC plant there is a working fluid circuit that is similar to a steam cycle.
- As a working medium of the working fluid circuit here does not contain water vapor, but usually organic media, eg. As butane, toluene, silicone oil or ammonia, which have a low evaporation temperature in relation to water.
- the working fluid in an ORC system is usually pressurized by a pump.
- the pressurized working fluid is then heated in an evaporator.
- the working fluid is evaporated and optionally overheated.
- the vaporized or superheated working fluid then passes to a steam turbine.
- the working fluid is expanded to a lower pressure to generate mechanical energy and then condensed.
- the working fluid is then returned to the evaporator, where it is reheated and re-evaporated or overheated.
- the evaporation temperature is higher than that of water.
- ORC systems can be advantageously used for generating electrical or mechanical energy from heat, especially when the available temperature gradient between a heat source and a heat sink is too low to operate a heat engine, such as a turbine, with water vapor.
- ORC plants are not only operated with heat from incinerators.
- the heat required for operating an ORC plant can also be obtained geothermally or come from solar power plants.
- ORC systems can also be operated with the waste heat of internal combustion engines (eg reciprocating engines).
- internal combustion engines eg reciprocating engines.
- the heat generated in the combustion device is conventionally transferred from the combustion device to the ORC system using intermediate heat carriers.

- thermal oil used as an intermediate heat transfer medium In order to operate an RC system with the heat from a combustion device, it is known to heat thermal oil used as an intermediate heat transfer medium to about 300 ° C. However, to ensure that the chemical structure of the thermal oil is not destroyed at this temperature, it must be continuously pumped through heat exchangers in a piping system. However, this causes a significant energy consumption and reduces the efficiency of the system.
- the object of the invention is to provide a device for generating electrical or mechanical energy with an RC system that receives heat from a combustion device and that can be reliably operated with high efficiency.
- This object is achieved by a device of the type mentioned, in which the heat exchanger is connected to the combustion device via a flue gas line to transmit the heat of the flue gas generated during combustion to the working fluid of the RC system.
- the temperature level of the guided through the heat exchanger flue gas is lowered and if a part of the thus cooled flue gas can be returned via a further flue gas line in front of the heat exchanger in the flue gas line.
- the flue gas generated during combustion can be mixed with already cooled flue gas and set a lower temperature level in the heat exchanger.
- the temperature level in the heat exchanger is preferably adjusted by changing the amount of recirculated exhaust gas. According to the invention, a temperature of 150 ° C. to 300 ° C. can be selected as the temperature of the cooled exhaust gas.
- flue gas is generated by burning a solid, gaseous or liquid medium, in particular by burning biomass, which contains heat.
- the heat of the flue gas is fed to a heat exchanger acting as a working medium evaporator in an RC system.
- the generated flue gas is passed through the heat exchanger for this purpose.
- the guided through the heat exchanger flue gas can be sucked with a flue gas blower and fed through the other flue gas line in the flue gas line. It is particularly advantageous if a circulation blower is arranged in the further flue gas line, which sucks the flue gas passed through the heat exchanger and conveys it into the further flue gas line.
- the RC system includes a working as a working fluid condenser heat exchanger, which is connected to a cooling water circuit to dissipate via the cooling water circuit, the condensation heat of the working fluid.
- the cooling water circuit is preferably also guided by a further heat exchanger which extracts heat from the flue gas passed through the heat exchanger.
- the RC system may include a feed pump that moves the working fluid from the heat exchanger operating as a working fluid condenser to the heat exchanger.
- the working fluid can be conveyed through a recuperator arranged in the circuit for the working fluid upstream of the heat exchanger.
- One idea of the invention is in particular to adjust the temperature of the flue gas stream before acting as evaporator for working heat exchanger by changing the mass flow of the cooled flue gas by throttling by a flue in the other flue gas line, which at least partially recircles the flue gas to the heat exchanger.
- An idea of the invention is also the temperature of the flue gas stream before the working medium heat exchanger by changing the speed of a fan arranged in the further flue gas line over which the flue gas is at least partially returned to the heat exchanger.
- the device may contain a flue gas flap arranged in the flue gas line, with which the flow of flue gas from the heat exchanger to the further heat exchanger or into the bypass line can be prevented. Also in the flue gas line between the combustion device and the heat exchanger, a flue gas flap may be provided.
- a conduit with a flap for supplying fresh air into the heat exchanger In this way it can be ensured that the heat exchanger and fresh air can be cooled.
- the device is advantageously formed with a chimney for releasing cooled flue gas.
- the RC system in the device according to the invention can be designed both as a small or large home plant, as a large industrial plant or as a power plant for municipalities.
- a home installation is understood to mean a system with which the energy supply including the air conditioning of office buildings, garages, and hospitals can be guaranteed.
- An industrial plant is a plant which supplies industrial production plants, in particular production plants of the automobile industry, eg paint shops with electrical energy, for which not only electricity but also heat at different temperature levels has to be provided.
- the device according to the invention has a simple apparatus design. The corresponding investment costs are therefore low.
