BIOMASS FIRED CHP PLANT BASED ON AN ORC CYCLE - PROJECT "ORC-STIA-ADMONT"

Obiettivo

The project proposed mainly focuses on the implementation of a biomass-fired CHP plant based on an ORC process (Organic Rankine Cycle) as a first demonstration within the European Community. An ecological and cost-effective operation of the process is only possible, if not only the electricity but also the heat produced by the ORC process can be utilized. The proper integration of the ORC process into the heat supply system and the installation of a flue gas condensation unit result in a maximum increase in the total efficiency of the whole process. After commissioning the plant will supply STIA-Holzindustrie GmbH with process and space heat and the Benedictine Monastery of Admont with space heat from biomass.
Furthermore, the ORC process covers almost half of the electricity demand (+/- 45%) of STIA-Holzindustrie GmbH on a renewable basis. Only sawdust and chemically untreated wood residuals arising in-house will be fired at the plant. In this way it will be possible to substitute fossil fuels at the Benedictine Monastery of Admont (heavy heating oil) and at STIA-Holzindustrie GmbH (light heating oil) as well as electricity from fossil fuels. A further aim of the project is the reduction of dust emissions with the flue gas a rotational particle separator, which also represents a new and innovative technology, will be placed behind the biomass-fired combustion unit. It precipitates solid and liquid particles >0.1 µm and reaches almost the same precipitation efficiencies as electrostatic precipitators, with investment costs only 30%-40% higher than those of multi-cyclones.L%

The main innovative component of the process is a biomass CHP plant based on an ORC process (electric nominal capacity : 400 kW, thermal nominal capacity : 2.25 MW). A silicon oil is utilized as the organic working medium in the cycle or a thermal oil boiler, respectively (nominal capacity 3.2 MW). the pressurized organic working medium will be vapourized by the thermal oil and then expanded in a turbine which in its turn drives the generator. Subsequently, condensation of the working medium takes place at a temperature level which allows the heat recovered to be utilized (hot water +/- 90°C). The liquid working medium will then be restored to an appropriate pressure level by means of a pump. In this way it is possible to use the electricity produced by the generator as well as the heat produced in the condenser (electrical efficiency : 10%; thermal efficiency : 80.8%; overall efficiency : 90.8%; related to NCV of the fuel). One innovative aspect of the biomass CHP plant proposed is the choice of a new,
environmentally friendly and suitable organic working medium necessitated by the higher temperature levels on the hot and cold side of the ORC process as compared to electricity-only applications. A further innovative aspect is the first demonstration of docking an ORC plant to a biomass-fired furnace via a thermal oil cycle. the further innovative components of the plant comprise glue water injection into the secondary combustion chamber of the biomass-fired furnace and the rotational particle separator. Due to the urea content of the glue water this waste stream can be used as a NOx-reducing agent similar to conventional SNCR processes. It can be considered as an innovative technology since no experience has yet been gathered regarding this method. The rotational particle separator is a new technology for the efficient precipitation of solid and liquid particles >0.1 µm from gas streams. Since this is the first time that it will be used in a large-scale plant and at temperatures of about 400°C, it can also be considered as an innovative technology.
