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)

- 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 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.
