Instytut Energetyki
For the 55 years the research realized by the
Institute has been focused on maintenance,
exploitation and development of national
energy system based on fossil fuels: hard coal
and lignite.
IEn has carried research and scientific
analysis for the commercial power
engineering, focusing on combustion
processes, thermal plants, power system
planning, high voltage technique, power and
special transformers, materials technologies,
electrical power distribution equipment and air
pollution control.
Moreover IEn has provided research support
regarding energy problems for the government
agencies.

The RFCS project BOFCom (Application of the Biomass, Oxyfuel and Mild Combustion Combination
for the utilisation of pulverised coals for electricity generation) has opened research in the clean coal
technologies area.
FP5 project BioFLAM (Combustion Behaviour of “Clean” Fuels in Power Generation ) has opened
research in the area of biomass at IEn
FP6 transfer of knowledge the project BIOFUCEL (Research and development of solid oxide fuel
cells (SOFC) technology for stationary applications based on biomass gasification and natural gas)
has initiated the fuel cells research programme

technologies:
Biomass burners
Biomass co-firng
- increase of renewable energy (co-firing, biomass burners)
- decrease of NOx from utility boilers
below 200 mg/Nm3 after year 2015,
- substantial decrease of CO2 emission
(oxy-combustion)

Implementation
Instytut Energetyki
Two burners fired with wood dust from board production at fiber boards
company FIBRIS SA in Przemyśl. The burners of changeable heat power in
range from 1 to 3 MW were developped and adopted for operation with coal
fired stoker boiler OR-32.
Next two burners have been delivered for two similar OR-32 at another board
company - Koniecpolskie Zakłady Płyt Pilśniowych SA.
Special 5 MW burners for rural biomass combustion were designed for the
Dolna Odra power plant. The burners are a part of 20 MW biomass co-firing
installation designed by IEn. The installation is currently mounted and will
start in mid 2010.

Instytut Energetyki
Development of own design of swirl burners for
pulverized coal – over 20 years of experience,
implementation in dozens of utility boilers:
- high stability burners and start up burners,
- low NOx emission burners - within more than 15
years of co-operation with ECOENERGIA the burners
were implemented in 52 boilers
Example No 3
Low NOx combustion
Instytut Energetyki
Decrease of NOx from utility boilers below 200 mg/Nm3 after year 2015
requires a new approach.
Combination of primary combustion modifications with SNCR (selective Non-
catalytic Reduction) at boilers over 500 MW heat output is a subject of
common research financed by one of Polish power plants.
This could be a cheaper alternative to SCR (Selective Catalytic Reduction)
method applicable for retrofit of relatively old Polish power plants.
The OP-650 boiler has been already reconstructed and combustion
optimization is currently going on. Emission target <300 mg/Nm3 is to be
obtained by primary methods while final reduction below 200 mg/Nm3 will be
achieved by SNCR.
The results should be known in mid 2010

A solution for clean coal technologies?
IEn has invested in 0,5 MW combustion stand enabling
combustion experiments in semi-industrial conditions.
Results:
• two research projects has been performed resulting with
prototype of „oxy-burner” for coal (Polish patent application No
P–389182 )
• substantial participation in Polish national strategic project
(2010-2015) on oxy-combustion technologies

Biomass gasification
For distributed energy production we see
future in combination of modern
gasification technologies with fuel cells,
which allows for over 60 % efficiency in
electricity generation. The air gasification
of wood chips of 10% moisture content
produces a gas of low heating value in the
range 5 to 6 MJ/Nm3.
