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

Chips cost 40 – 60 Euro/tonsHeat cost 6 - 8 cEuro/kWh

CHPCombined production of Electric and Thermal power from biomass

Technologies– Steam (classical Rankine Cycle)

Power range 5 MWe 20 MWeAnnual use of wood higher than 50.000 tons/yearEfficiency about 15-25%

– Organic Rankine CyclePower range 450 kWe 1.5 MWeAnnual use of wood from 5.000 to 15.000 tons/yearEfficiency about 15%

Green CertificateTo improve the production of electricity from renewable energy source GREEN CERTIFICATES (about 10 c€ per kWh)

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
