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 1. 2. 3. 4. 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) 5. Group for law in field of environment and energy. 6. Group: Numerical calculation support during theoretical analyses of thermal – flow systems and designing (ANSYS Software)

The fields of potential cooperation • Alternative energy sources : geothermal, photovoltaic, biomass, waste biomass e. g. WASTE BIOMASS →→CLEAN GAS FUEL: Waste biomass pyrolysis gasification to H 2 production • Combustion of biomass in small and medium size boiler- optimization of burnout 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 CO 2 sequestration and storage CO 2 hydrates • Waste management • Audits, intelligent management of heat energy demand supply • Ceramic fuel cell

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

Solid biomass co-firing in 200 MWe power plant General assumptions: Biomass is combusted along with basic fuel in power plant unit 200 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/m 3 * Installation was commissioned in september 2007

Solid biomass co-firing in 200 MWe power plant Pellets Saw dust Future: Wood-chips Agro-Pellets

Solid biomass co-firing in 200 MWe power plant with high share of the biomass- goal Concept

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

Concept of liquid biomass co-firing in 200 MWe and 500 MWe power plant Complete installation of biomass co-firing on all power plants units is 300 000 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 MWe and 500 Mwe power plant Installation output: Unit 200 MWe has 6 burners (1 -1. 5 t/h)and 6 burners other types - ~~400 kg/hr; unit 500 MWe has 8 burners (1 t/h) Liquid biomass temperature (about 80˚ C) will be reached utilizing flue gases from SO 2 desorption installation

Concept of liquid biomass co-firing in 200 MWe and 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 generator power output - 16, 5 MWe

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

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