1 Combined Heat and Power Generation from Biomass ORC-Technology Dipl.-Ing. Hans Sanzenbacher, Managing Director Sofia, BULGARIA October, the 8th, 2013

2 The Organic Rankine Cycle (ORC) Thermal Oil 300 C 11 bar / 275 C Turbine 0,2 bar / 230 C G Generator Rankine-Cycle Power generation processwitha watersteamturbine, described first by the Scotish scientist William John Macquorn Rankine ( ) ORC- Evaporator Recuperator ORC = Rankine Cycle withan OrganicMedium Thermal Oil 200 C Organic Medium (e. g. Silicone Oil) ORC- Condenser ORC-circulation pump 80 C 60 C Water pump Heat Consumer 2

3 Why organic media for power generation? Many organic media with different properties are available, for each application the most suitable medium can be chosen Main advantages of the ORC-process compared to a water steam turbine process Totally closed system, no water required, no chemicals necessary Low operating pressure and temperature, for some media no superheater required Nocorrosion, noerosionin theturbine, causedbydrops Big controlrange(ofupto1 : 10), fully-automaticstart-upandstop-down Low effort for process control, operation and maintenance, compared to a steam turbine Applications Geothermal Power Plants Solar Thermal Power Plants Power Generation from waste heat (e. g. exhaustgas ofmotors) HeatandPower Generation (CHP) from Biomass Temperature [ C] Methanol 350 Ethanol propanol butanol octanol Entropy [kj/ kg K] 3

4 ORC-Applications In Europe more than 200 ORC-Biomass Power Plants are installed yet 4

5 Our motivation to come to Bulgaria Available Ressources High potential of wood waste from forestry and from wood working industry High potential ofindustrialwasteheat(e. g. cementindustry, power plants, maybe also from biogas motors in future) High potential for solar thermal power plants Political situation Power generation from Renewables is preferred and subsidied by the politics High feed-in-tariffsforelectricpower, generatedbythecombustionofsolid biomass, uptobgn 287,30 / MWh el (EUR 146,89 / MWh el ) Advantages to use biomass for energy production for the region Added value for the local forestry, additional jobs Becoming independent from energy imports and from fossil fuels Example: A biomass-fired ORC-modul, designed for 1000kW electric power, running 8000h per year with 75% load in average, generates 6000MWh electric power / year 6000MWh x BGN 287,30/MWh = BGN /a (according EUR /a) 5

6 The Company Companies history Operational business started in July 2011 with engineering services for ORC-power-plants Maintenance servicesfororc-power-plantssincejanuary2013 Design ofourownorc-seriesin 2013 Turn-over 2012 EUR 200T, estimated turn-over in 2013 > EUR 500T (Engineering, Service) : 7 employees(including management) Management The companywas foundedby3 engineers, eachwitha long-term experience in process heat technology systems with organic mediaaswellasin thedesign and implementationoforc-modules forbiomassapplicationsandin ORC-biomass-power-plants.

9 Our Experience When to use an ORC-module? Long-term availability of the biomass in the needed amount and quality Heatdemandofatleast 50% ofthecondensingheatoftheorc in average, in winter 100%, almost continuous heat consumption Heatisrequiredashotwater<= 120 C Andwhatcanwedo foryou? Preparing feasibility studies Basic engineering for ORC-biomass-power-plants Detail engineering and project implementation Ensurethatthefuelandtheequipmentfitstogether, for a high availability and life-time of the plant Ensurethattheheatdemandandthesizeoftheplant fits together, for maximum profit Assist youin thefinancingoftheproject During the AHK-business meeting Heat and Power Generation with Biomass" in Sofia, we hope to get in contact with consultants for energy projects, energy service providers, industrial clients consuming power and heat, industrial clients in the wood working industry, as well as with representatives from municipalities. 9
