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 1.Biomass, agrobiomass, RES, multifuels boiler 2.Power Production, reliability and improving of efficiency 3.Ecological effects of energy production 4.„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) Current working groups

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 H2 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 CO2 sequestration and storage CO 2 hydrates Waste management Audits, intelligent management of heat energy demand and supply Ceramic fuel cell

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

Installed Power of RES Generating Electricity ( ,65 MW ; MW) Biomass is the most suitable in our conditions to increase RES share in power production

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

General assumptions:  Biomass is combusted along with basic fuel in power plant unit 200 MW, Nr 1-8  Predicted biomass flow – 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

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

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

Complete installation of biomass co-firing on all power plants units is 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 MW e has 6 burners (1-1.5 t/h)and 6 burners other types - ~~400kg/hr; unit 500 MW e 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

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 C  pressure - 93 bar  generator power output - 16,5 MWe

 Concept allows to burn 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 250MWe 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).
