Presentation Transcript

  1. District Heating • Typical range of power 500 kWth – 20 MWth Optimum size about 1 MWth • Consumption about 1.000 tons/year compatible with local availability • Reduced impact • Repeatability • Contained costs Boiler Chips cost 40 – 60 Euro/tons Heat cost 6 - 8 cEuro/kWh District heating pipe

  2. CHP Combined production of Electric and Thermal power from biomass Technologies • Steam (classical Rankine Cycle) Power range 5 MWe  20 MWe Annual use of wood higher than 50.000 tons/year Efficiency about 15-25% • Organic Rankine Cycle Power range 450 kWe  1.5 MWe Annual use of wood from 5.000 to 15.000 tons/year Efficiency about 15% • Green Certificate • To improve the production of electricity from renewable energy source  GREEN CERTIFICATES (about 10 c€ per kWh) ORC Turbogenerator

  3. Pellets boiler – Typical installations • 8-10 kWth • Domestic heating • Production of hot air • Consumption: 0,6 – 2,1 Kg/h • Cost: 2.000 – 4.000 Euro • 25 kWth • Small houses • Production of hot water and hot air • Consumption about 5 kg/h • Cost 5.000 – 10.000 Euro • 110 kWth • Buildings • Production of hot water • Consumption about 20 kg/h • 35.000 – 50.000 Euro • It needs place to store Pellets boiler

  4. E. Logistic systems • Chainsaw • Transportation system with mobile engine • Timberjack (less used) • Tractors (in most of cases) SUPPLY CHAIN

  5. Supply chain - 1 Cut off using chainsaw Transportation with tractor Measurement and section

  6. Supply chain - 2 Transportation system with mobile engine Transportation with track trailer Heavy mobile chips machine Truck loading

  7. Next deliverables (short term) • List of regional stakeholder • Analysis of wood resources and energy • Demand Catalogue of technologies and logistic systems

  8. Proposals for next deliverables • Common template for deliverables • Set deadlines for deliverables • Next study tour: where ? when ? focus on: technologies ? Logistic systems ?
