Biomass CHP HRAST, Strizivojna

Project title: Steam-based cogeneration system with 20 t/h of superheated steam at 40 bar and 400°C fired with wood biomass with a capacity of 3,3 MW.
Investor: Strizivojna Hrast d.o.o.
Location: Strizivojna, Croatia
Construction completion: 2011.

Project description

Reasons for investing:

  • Investor is producing electricity in diesel generators because of limited grid capacity
  • There is an increased need for electricity due to increased parquet production
  • There is sufficient wood residue for a cogeneration plant
  • A new grid is being built by HEP in the meantime

Equipment dimensioning:

  • Steam boiler fired by biomass 20 t/h, 40 bar, 400°C
  • Condensing steam turbine with regulated steam extraction and a heat station 2x3 MW with parameters 90/70°C for wood drying kilns
  • Air condenser
  • Weekly biomass tank

Enerkon participated in the project by preparing:

  • All Cost-benefit analysis and Investment studies
  • Tender documentation for the delivery of the main equipment of the cogeneration plant by the "turnkey" model
  • Main design
  • Detailed design
  • As-built documentation
