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.

Development of new biomass burners

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

Oxy-combustion

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.
