Description
A device producing electricity and heat from biomass
Background and summary of the invention
The invention deals with a device producing electricity and heat from biomass operating on the principle of the Organic Rankin Cycle and a cogeneration unit.
Devices producing electricity by biomass combustion forming complex systems utilizing the waste heat generated by the process are known.
Devices producing electricity by means of the Organic Rankin Cycle (ORC) present an example of such devices. E.g. a two-stage ORC device system utilises heat from glassworks and similar operations producing extensive waste heat to heat the working medium. Heated working medium is forced to the working circle where it drives a turbine to produce electricity. After that the working medium, e.g. diphenyl or diphenyl ether transfers heat to the working medium of the second circuit, which is cooler and the whole process may be repeated this way on the cascade principle.
Another device utilizes heat from direct biomass combustion to heat the working medium driving a turbine in the ORC cycle. The waste heat from the turbine is forced to a wastewater plant sludge drier, where it dries sludge used afterwards for combustion in a boiler and for heating the working medium used primarily for driving a turbine. The working medium cooled by drying is forced to a combustion boiler to pre-heat air for the maximum efficiency of combustion.
Further possibilities of electricity production are represented by turbines driven by hot gas obtained by combustion in a boiler. Hot air from the turbine comes to the first boiler where it heats water, which in the form of steam drives a steam turbine and simultaneously goes to the second boiler from which it goes to dry air in the first and the second driers together with the waste heat from the steam turbine.
Turbines driven by gas combustion engines are also used for electricity production, where the gas is obtained by pyrolysis-combustion of biomass.
Finally a device is known specially designed for utilization of wastewater plant sludge mixed with vegetable or biological material. The fermented and dried mixture is combusted in a fluid boiler, the heat from the combustion is used in the ORC for electricity and heat production. The sludge is at the same time stored in a digestion tank where the emerging biogas is used to drive a cogeneration unit, i.e. for further electricity production. The heat from the fluid boiler and the cogeneration unit is used for heating air in a drier. The combustion heat gas from the drier is used for sludge fermentation. The disadvantage of this device is that it processes wastewater sludge, which is not always available and is not much suitable as fuel as it contains heavy metals and further harmful substances (the biological material may be contaminated etc.). A fluid boiler as well as a digestion tank are moreover demanding technologies in terms of investment, construction and space, and cannot be implemented to all locations, having to meet strict environmental conditions.
It is an object of the invention to develop a device for energetic use of biomass particularly in the form of vegetable biomass pellets that would eliminate the disadvantages of the above solutions.
This object is accomplished by development of a device producing electricity and heat from biomass according to this invention.
The principle of the invention is based on the fact that the gas section of the cogeneration unit and the heat source for the ORC device are formed by at least one pyrolysis reactor for pyrolysis combustion of pellets or briquettes, which is connected to an input to a gas combustion engine or a turbine, the pyrolysis reactor includes an oil circle, which is connected to the input to the ORC device, and the output of heat from combustion gas from the gas combustion motor is led to the circuit of the first heat exchanger, which is connected to the input to the ORC device.
This arrangement enables the pyrolysis reactor to be used simultaneously by both, the cogeneration unit and the ORC device, and the ORC device moreover uses the heat from the gas combustion engine combustion gas.
In an advantageous embodiment the heat output from the gas combustion engine combustion gas leads from the first heat exchanger to the second heat exchanger used for heating a drier, so that the combustion gas still having sufficient temperature may be used for drying various materials (biomass) having too high humidity to be directly combusted.
Another advantage is that the pyrolysis reactor includes a water circuit and the gas combustion engine includes a water circuit, while both water circuits are connected to a circuit of the third heat exchanger, which is connected to the second heat exchanger used for drier heating, and the gas combustion engine includes an air circuit, which is connected to the third heat exchanger. The heat generated in the device for efficient drying of wet biomass is thus utilized.
In an advantageous embodiment the drier output is led to the input of a compaction press making pellets or briquettes, so pellets or briquettes may be produced directly from the biomass.
The biomass drier and/or compaction press connected to the drier are advantageously connected to the electricity output from the ORC device and the cogeneration unit.
A substantial advantage of the device according to the invention is based on the fact that it uses the waste heat from the first phase of electricity production (from the cogeneration unit) for electricity production in the second phase (the ORC device).
Another advantage is based on the fact that the remaining heat after the second phase of electricity production (the ORC device) is used for pre-drying biomass for pyrolysis.
The overall efficiency of the device according to the technical solution is thus somewhere between 80-90%, which remarkably exceeds efficiencies achieved by similar devices so far known.
Brief description of the drawings
The technical solution will be explained in detail by a driving, where Fig. 1 shows a schematic diagram of the device according to the invention.
Detailed description of the preferred embodiments
The below described and depicted particular examples of the invention are considered illustrative and they in no way limit the invention to the examples herein presented. Those skilled in the art will find or will be able to find more or fewer equivalents to the specific embodiments of the invention herein described in their routine experimental work. These equivalents will also be included in the claims below.
The device producing electricity and heat from biomass as shown by the example in Fig. 1 consists of a cogeneration unit 2, which involves a pyrolysis reactor 8, a gas combusting engine 3 and a generator 4. Wood gas is generated by pyrolysis combustion of wooden pellets and briquettes 1 in the pyrolysis reactor 8. The wood gas from the pyrolysis reactor 8 is led as fuel via the gas section of the gas processor to the gas combustion engine 3. Wood gas combustion in the gas combustion engine 3 and subsequent rotation of the generator 4 produces electricity, which leads through the output 6 from the cogeneration unit 2 to the public distribution network.
The heat output Y7_ from the combustion gas from the gas combustion engine 3 leads the heat to the first heat exchanger 9, from which the heat transferred to oil liquid leads to the input 16 to the ORC device 5, where thermal expansion of the liquid makes the turbine rotate and generate electricity, which leads via the output 6 from the ORC device 5 to the public distribution network.
The device producing electricity and heat from biomass includes in total four heat exchangers 9, 10, 12 and 14, for utilization of the heat generated during the electricity production. The first heat exchanger 9 utilizes the heat extracted from the
combustion gas from the gas combustion engine 3 and ensures oil medium heating in the ORC device 5.
The second heat exchanger 10 utilizes the heat extracted from the combustion gas from the gas combustion engine 3, led through the output \7_ via the first heat exchanger 9 to the second heat exchanger 10 to heat the drier 7. The heat obtained this way is led into the drier 7 for biomass drying.
The third heat exchanger 1_3 gains heat from a water circuit 18 of the pyrolysis reactor 8, from the water circuit 19 of the gas combustion engine 3, and from an air circuit 20 of the gas combustion engine 3, which is mixed with sucked ambient air 21
The ORC device 5 is connected to a low-temperature circuit of the fourth heat exchanger 12, where the waste heat from the ORC device 5 is directed, i.e. the heat of the liquid after actuation of the turbine, which is thus used for remote heating of buildings. The fourth heat exchanger 12 is adapted to possible cooling of the liquid circulating in the circuit when heat is not used for heating purposes, e.g. in summer.
According to the example in Fig. 1 the biomass drier 7 is connected to a compaction press H, and both the drier 7 and the compaction press H are connected to the electricity output 6 from the ORC device 5 and from the cogeneration unit 2.
