current technologies for heat and combined heat & power generation

What means SWH?

SWH = Strom und Wärme aus Holz(Energy and Heat from wood)

Österreichische Bundesforste AG

Wärmebetriebe GmbH

&

• largest forest company and owner of forest in Austria

• easy availability of biomass in all provinces

• professional resource logistics

• forestry strictly based on sustainable development

Die ÖBf AG – Austrian Federal Forest

Wärmebetriebe

• market leader in biomass in Austria

• forerunner of environmentally friendly

heating systems in Austria

• 30 years experience

• planning, implementation, management of district heating networks and heating plants

Development of SWH

� 2002: SWH started with the purchase of one heating plant

� 2003: 3 heating plants and heating nets were handed over to SWH by WBG (one of the shareholders)

� 2004: project development of several power plants for green electricity and additional heating plants

� 2005: project development resulted in the construction of 5 major power plants - SWH holds at least 51% share

� 2006: further project development and implementing operational concepts

� 2007: 19 plants in operation, 7 plants under construction, internalization prepared

SWH - references

SWH – stands for

• Biomass-fuelled electricity and heat generation

• Co-operation with agriculture, forestry,

• communities and industry

• Reliability and professional resource logistics

SWH - our products

Heat from wood

• local- and district supply for heating systems

and hot water processing

• process heat (hot water/steam) for

industrial plants

Electricity from wood

… from combined heat and

power plants (CHP) to feed into the net

biomass offers several advantages

• Regional value added by utilization

of regional biomass

• A CO2 neutral energy generation

• A renewable source of energy

• Guaranteed supply by sustainable

natural resource management

• Protection of jobs in rural districts

• Leadership in technology through

increasing application

biomass combustion

• high temperature process (800-

1.200 °C)

• air ratio λ > 1

• chemical energy stored in fuel

(heating calorific value) is set free

by oxidation of organic matter and

heats the flue gas
