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

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
Solid biomass co-firing in 200 MWepower plant Saw dust Pellets Future: Agro-Pellets Wood-chips
Solid biomass co-firing in 200 MWepower plant with high share of the biomass- goal Concept
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
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
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
Concept of liquid biomass co-firing in 200 MWeand 500 MWe power plant- pilot installation
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
Concept allows to burn 250 000 t/year straw Installation cost is about 50 mln euro New unit for biomass combustion
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).
