Danish technology for power station always ahead in the

search for efficiency


Group


Fuel flexibility

• In addition to the increase of efficiency, the Danish power industry had to

face the issues related to fuel flexibility

• The energy model of Denmark had to adapt to the primary energy market in

order to:

– Be independent from large sources of primary energy that may “capture” the

power industry

– Adapt to new possibility of sources of cheap primary energy

– Follow the trend of demand for cleaner technology and renewable energy

– Be load flexible in order to maximise the use of wind energy

– Combine all the above points

Hazira: multi fuel boiler

for a steel mill complex

Essar steel mill complex BWE has awarded a contract for the supply of two

drum type boilers for power and steam production for the Hazira steel mill

complex (Gujarat-India) .

• The two Drum Boilers are designed to fire a number of different fuels.

• Main fuels are COREX Gas and COREX Coal besides a variety of other

coal types.

• The boilers are, however, also capable of firing:

• COREX Coal Fines,

• Corex Coal Dust,

• HFO and LDO.

Ultra Super Critical Boiler Technology

for the power industry

Worlds highest efficiency

decrease of CO2

use less fuel per produced MWh

BWE Hybrid Multi Fuel concept

Coal, oil, gas and biomass used on the same boiler

individually or simultaneously

Fast reaction time on power demand

BWE boiler very fast ramp-up time (5% / Min)


Group


- Efficient hybrid power production

- Use of local biomass

- Potential local earnings

Build new plants (small or large) using BWE hybrid- or

biomass-concept using proven technology

Retrofit and upgrade old plants by using BAT

Use the multi fuel concept in new builds and

retrofits

(Same boiler can use coal, gas,

oil and biomass)

What BWE can offer to Russian market?


Group


What BWE is doing/could do in the russian market?

•Cooperation with local boiler manufacturers for new technology

introduction for high efficiency power boilers

•Cooperation with Russian utilities for conversion of old power

plants to multi fuel technology

BWE has started development of cooperation with Russian

companies but so far developments or contracts have been

achieved.
