Complete design and consulting services as well as construction supervision of the erection of a biomass-fired combined heat and power (CHP) plant (1 MWel, 27 MWth) with combined heat and power, a storage site incl. siding track and storage facility for bark, wood chips and sawdust as part of the district heating system for the city of Hall in Tirol.

The biomass CHP plant simultaneously generates electricity and heat by burning biomass energy sources (such as wood and bark chips, sawdust, etc.). In a combined heat and power system (ORC-plant) a medium is evaporated in a closed circuit cycle and used to drive a steam turbine. The turbine is directly coupled to a generator for the generation of electricity. The condenser delivers the condensation energy of the medium to the district heating network. This system makes optimum use of the heating value of the biomass and ensures optimum efficiency of the overall system.

For generating the necessary heat energy, a hot-water boiler and a thermal oil boiler are installed, with a heating capacity of 7.5 MW each. Two natural gas fired hot-water boilers with a total capacity of 22 MW serve to cover peak loads and potential failures.

On account of the location of the plant, waste gas cleaning must fulfil stringent requirements in accordance with the Austrian Immission Control Act (atmospheric pollution). To meet the permissible dust emission limit of 5 mg/m³, a wet precipitator was installed, and a SNCR-process applied to reduce nitrogen oxides.
