С помощью когенерационных установок Polytechnik обеспечивает экономически эффективные способы производства тепла и электроэнергии из биотоплива. Комбинированное производство тепла и электроэнергии осуществляется с помощью паровой турбины или ОРЦ-турбины (органический цикл Ренкина). Паровые когенерационные установки могут представлять из себя как классические установки насыщенного пара, так и установки высокого давления с конденсационными турбинами. В установках по комбинированному производству тепла и электроэнергии для ОРЦ-турбин в качестве средства передачи энергии используется термомасло, которое обеспечивает температуру в технологическом процессе около 310°С. ОРЦ-установки особенно подходят для клиентов, у которых при потреблении тепла часто возникает необходимость в частичных нагрузках.
Polytechnik предлагает полный спектр услуг: от логистики топлива до очистки дымовых газов и выполнения полного цикла технологического процесса.

Project description:
Biostrom Oberhausen GmbH & Co. KG operates a biomass cogeneration plant on the premises of Energieversorgung Oberhausen AG (HKW II). There is already a gas cogeneration plant in operation, as well as a gas turbine for power generation and other steam boilers. The purpose of the biomass heating plant is the generation of electricity and heat, working with overheated steam as the operating medium according to the principle of cogeneration (CHP).
In general, the biomass cogeneration plant consists of a high-pressure steam boiler with an output of 12.15 MWth as well as a steam turbine with a max. output of 3.2 MWel and a max. heat output of approx. 9 MWth, which can be decoupled.
The electricity produced by the steam turbine is fed to the power grid of the local distribution system operator (EVO Energie-Netz GmbH) and the simultaneously produced heat is supplied to EVO’s district heating system."
Volac
Boiler output: 2 x 10,000 kW (3,000 kWel)
Combustion system: hydraulic reciprocating step grate
Fuel: forest wood chips, bark
Year of construction: 2015
Location: Great Britain
Project description:
The cogeneration plant consists of 2 biomass-fired thermal oil boiler plants (design 13 bar / 340°C,10 MWth each), which supply a ORC turbine (Turboden 28 CHP). The turbine is equipped with an asynchronous generator (3.0 MWel). The waste heat of around 13.5 MW is used for processing purposes (dairy). In order to accommodate process-related fluctuation in the heat requirements, there are recooling plants in the outside area.
During the planning and construction of the whole boiler and energy generation plant, special attention was paid to future highly efficient operation as well as operational safety. The commissioning phase took place in 2015.
Hillerod Forsyning
Boiler output: 2 x 12,730 kW (2 x 2,600 kWel)
Combustion system: hydraulic reciprocating step grate
Fuel: forest wood chips, bark
Year of construction: 2015
Location: Denmark
Project description:
The cogeneration plant consists of 2 biomass-fired thermal oil boiler lines (design 13 bar / 340°C,12.7 MWth each), which supply a ORC turbine (Turboden 26 CHP) each. The turbine is equipped with a synchronous generator (2.6 MWel each, 5.2 MWel in total). The generated approx. 30 MW of heat is fed into the connected district heating system of the city of Hilleroed.
During the planning and construction of the whole boiler and energy generation plant, special attention was paid to a highly efficient operation. Besides other things, a flue gas condensation plant, a heat pump for return temperature increase (screw compressor) as well as the recirculation of several sources of waste heat were planned and integrated in the entire plant, in order to use all energy flows. This allows for overall efficiencies of up to 117%.
The fuel logistics have also been fully automated: a weighbridge, fuel unloading areas and loading cranes are integrated in the whole plant control and operate fully automatic. Commissioning took place in 2016/2017.
BIO Energie Lozere
Boiler output: 2 x 16,000 kWth (7,500 kWel)
Combustion system: hydraulic reciprocating step grate
Fuel: hydraulic reciprocating step grate
Year of construction: 2009
Location: France
Project description:
The cogeneration plant consists of 2 biomass-fired super-heated steam boiler plants (design 29 bar / 470°C - 16.1 MWth each), which supply steam to a steam turbine. The turbine is designed as an extraction condensing turbine (7.5 MWel). The extraction volume is regulated and heats a heat condenser (decoupling up to 23 MWth), which supplies the district heating system. Additionally, a hot water boiler (10 MWth) is installed for the district heating system in winter. In the exterior area there is a recooling plant to precipitate the turbine steam in the condenser.During the planning and construction of the whole boiler and energy generation plant, special attention was paid to future highly efficient operation as well as operational safety.
