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 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 CO2 hydrates
• Waste management
• Audits, intelligent management of heat energy demand and 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/m3
* Installation was commissioned in september 2007

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 - ~~400kg/hr; unit 500
MWe has 8 burners (1 t/h)
 Liquid biomass temperature (about 80˚ C) will
be reached utilizing flue gases from SO2

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 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).
