Cogeneration plants with Turboden ORC can produce heat and electrical power from biomass with high efficiency and user friendly operation. The generated power usually ranges between 400 kW and 5 MW electric.

BiomassHeat Recovery Geothermal Solar Thermal Power

Modular ORC Units for biomass applications

Page 4: Paolo Bertuzzi Turboden

Advantages of ORC technology

Technical advantages

Very high turbine efficiency (up to 85%)

Low mechanical stress of the turbine due to the low peripheral speed

Low RPM of the turbine allowing the direct drive of the electric generator without reduction gear

No erosion of blades, no water treatment system due to absence of water

Low mechanical stress of the cycle due to much lower pressure than steam cycle

Operational advantages / results

Automatic and continuous operation

Simple start-stop procedures

No operator attendance needed

High efficiency at partial load and

operation down to 10% of nominal power

Very safe and quiet operation

Low maintenance requirements: planned

maintenance once per year, no major

overhauls

Very High Availability (e.g. Admont, AUT:

operation since 1998, availability > 98%)

Long life – designed for 20+ years

Translate in user advantages

Why Distributed Biomass-Fueled CHP?

sustainable & renewable: CO2 neutral and re-growing fuel

local energy source: no dependence on volatile global fossil fuel markets

local base-load electric power: relief for congested transmission lines

impact on economy: uses a local supply chain and keeps energy revenues local

clean technology: small plants - easier permit

The District Heating Model in Central Europe

Small and medium-size communities (typically 2000-10000 inhabitants) Starting point: main heat users as community buildings, school/college,

hospital, large commercial & industrial users Small residential users can follow Modern hot water piping infrastructure has a life time of 40-50 years Strong regional policy support for sustainable development:

Investment incentives depending on region Long-term feed-in rates for electricity from biomass

Financial/Investment schemes: Local utilities Co-ops with farmers, forest owners & communities Local private long-term thinking investors
