Turboden has signed an order with Starwood Orman Ürünleri Sanayi A.Ş for a new 5.5 MW CHP plant for its biomass plant to be installed in Bursa, Turkey. The Turboden ORC system will produce 5.5 MW electric and 29.5 MW thermal. The project is included in a bigger plant that calls for the expansion of Starwood MDF production facility in Bursa.
A 50 MWth biomass boiler fed by bark and chipboard production residues will supply heat for the rotary dryer and for the ORC, that will also produce hot water at 90 °C for dryer purposes. The integration of the ORC in an MDF production plant is an attractive application thanks to the possibility to produce a part of the own consumption of electricity of the plant and to implement cogeneration systems without significant changes to the typical MDF process scheme. This solution has also the advantage of extremely low operation and maintenance costs and limited additional costs compared to the heat only solution, leading to an optimal pay back of the additional investment.
The ORC turbine, constructed by the new Turboden Turkish daughter company, Turboden Turkey ORC Turbo Jeneratör Sanayi Anonim Şirketi, recently established in Ankara, will grant Starwood the access to the local content related additional incentives offered by the Turkish Government for renewable energy generation. A Turboden local service team, already active in the Turkish territory, will provide on-site works and after-sales services.
The Starwood project is the third biomass plant in Turkey for Turboden, after the 1 MW ORC unit supplied to Kastamonu Entegre in Gebze and the 200 kW ORC unit installed in Bursa for Marmarabirlik, a further important step of Turboden advance in the Turkish market, not only for geothermal application but also for biomass exploitation.
Since 2011 Turboden has successfully delivered also two 5.3 MW waste-to-energy ORC units to ITC-KA Enerji Üretim Sanayi ve Ticaret A.Ş. in Mamak and a 3 MW geothermal unit to AFJET A.Ş. in Afyonkarahisar.
Recently other two large-sizes CHP plants have been awarded. A Turboden 5.5 MW CHP plant will be installed in a sawmill and pellet factory in Russia with the Spanish general contractor Prodesa Medioambiente. In this project, barks and waste branches will feed a thermal oil boiler, coupled with the ORC unit. The heat generated by the ORC system will feed, on the one hand, the drying chambers of the existing sawmill, that will be enlarged, and on the other, a pellet production line of 80,000 t/y.
A further CHP module will be installed in the Philippines, the first biomass large ORC plant in South-East Asia. The unit will recover thermal power from the combustion of corn cob and rice husk to produce up to 5.8 MW electric. The thermal power discharged by the ORC will be efficiently used to dry cereals. In both projects, the customers will also rely on the capability of the Turboden ORC to work on island mode, i.e. to ensure electricity generation to feed the production process consumptions during power failures of the main grid.
