  1. CLUSTER FOR ENERGY GENERATION IN MEGA- AND NANO- SCALE prof. Halina Kruczek Head of steering committee E-mail: hkruczek@pwr.wroc.pl Tel/fax: +48 71 320 39 42 POLTEGOR – MEMEBER OF Cluster Presentation: BARBARA ROGOSZ PhD Janusz Lichota Cluster Secretary Lichota@pwr.wroc.pl German-Polish Workshop Wrocław 20 IV 2009

  2. Content • The organization structure • The fields of potential cooperation • Green energy production in power plant – co-firing liquid and solid biofuel in boiler of energy sector - comparison

  3. Cluster- current topics Current working groups • Biomass, agrobiomass, RES, multifuels boiler • Power Production, reliability and improving of efficiency • Ecological effects of energy production • „group carbon”, clean coal technology, conversion of brown coal, analysis of new resources (field Legnica) • Group for law in field of environment and energy. • Group: Numerical calculation support during theoretical analyses of thermal – flow systems and designing (ANSYSSoftware)

  4. The fields of potential cooperation • Alternative energy sources :geothermal, photovoltaic, biomass, waste biomass e.g. WASTE BIOMASS →→CLEAN GAS FUEL:Waste biomass pyrolysisgasification to H2 production • Combustion of biomass in small and medium size boiler- optimization ofburnout and emission, certification • Co-combustion of biomass in existing Power &Heat Plants –with high share of biomass • Micro CHP • Lignite pretreatment: UC gasification, Lignite predrying etc. • Clean coal technology: • Gasification of coal for hydrogen production • Zero-emission technologies – oxy- fuel, capture technology of CO2 sequestration and storageCO2hydrates • Waste management • Audits, intelligent management of heat energy demand and supply • Ceramic fuel cell

  5. Greenenergy production in power plant- cofiring liquid and solid biomass in boiler of energy sector

  6. Installed Power of RES Generating Electricity (2000- 690,65 MW ; 2015 - 2500 MW) Biomass is the most suitable in our conditions to increase RES share in power production

  8. Sources of Biomass in Poland Straw [th.ton] Gradziuk P. „Słoma energetyczne paliwo”, W-wa 2001 Forests Pl [th.ha] Date statystyczne GUS, za rok 2002 Complexes of usefulness of agricultural soils Instytut Upraw Nawożenia i Gleboznawstwa, Puławy Uncultivated lands [th.ha] Date statystyczne GUS, za rok 2005

  9. Biomass co-firing for 200 MWe power plant as an example

  10. General assumptions: Biomassis combusted along with basic fuel in power plant unit200 MW, Nr 1-8 Predicted biomass flow – 100.000 t/year Maximal biomass share in mass fuel flow is 10% Predicted biomass weight 0,25÷0,60 t/m3 Solid biomass co-firing in 200 MWepower plant * Installation was commissioned in september 2007

  11. Solid biomass co-firing in 200 MWepower plant Saw dust Pellets Future: Agro-Pellets Wood-chips

  12. Solid biomass co-firing in 200 MWepower plant with high share of the biomass- goal Concept

  13. Concept of liquid biomass co-firing in 200 MWeand 500 MWe power plant K 1 Coal storage K 2 Oil container K 3 K 4 Coal storage OIL heater Flue gases Flue gases Scheme of installation

  14. Complete installation of biomass co-firing on all power plants units is300 000 t/year. Heat share of liquid biomass in co-firing is 12%-24% depending on type of bio-oil. Concept of liquid biomass co-firing in 200 MWeand 500 MWe power plant

  15. Installation output: Unit 200 MWehas 6 burners (1-1.5 t/h)and 6 burners other types - ~~400kg/hr;unit 500 MWehas 8 burners (1 t/h) Liquid biomass temperature (about80˚ C) will be reached utilizing flue gases from SO2 desorption installation Concept of liquid biomass co-firing in 200 MWeand 500 Mwe power plant

  16. Concept of liquid biomass co-firing in 200 MWeand 500 MWe power plant- pilot installation

  17. Plans_New units for biomass combustion Unit consists of grate boiler adopted to straw combustion and condensate turbine: steam flow- 64 t/h steam temperature- 525 C pressure- 93 bar generatorpower output - 16,5 MWe

  18. Concept allows to burn 250 000 t/year straw Installation cost is about 50 mln euro New unit for biomass combustion

  19. Power plant unit 250MW with CFB (circulating fluidized bed) Construction of new unit 250MWeinstead of old unit along with CFB. Utilizing existing turbine and infrastructure. Turbine adaptation relays on exchanging HP- and MP–part (LP-part is new).
