Progress beyound the state of the art:
Emissions
Tougher EU emission standards especially on dust and the need for biomass fuel flexibility (not only prime wood chips) will boost the Dall Energy advantages compared with the traditional technology.
Today the dust limit is 100 mg/Nm3, However the if the flue gas is not condensed and by that “washed” then the limitation is 40 mg/Nm3 (for dry systems).
In the new EU Directive (EU) 2015/2193 there will be the following emission limits when it comes to dust:
• Plants larger than 50 MWthermal = 20 mg
• Plants between 5-50 MWthermal = 30 mg
• Plants between 1-5 MWthermal = 50 mg
The directive will be enforced from the end of 2017.
Dall Energy technology can due to its very low dust emissions comply with the regulation without adding any other filtering technologies. However, competing technologies will either have to add electro-filters or bag-filters in order to stay within the limits of the directive.
Load flexibility
The Dall Energy technology’s load flexibility is outstanding compared to conventional technology. Easy to adjust in a range going from 10 to 100% load while keeping high efficiency.
This feature is very interesting for industries using steam and with load variations (night and day) or for district heating companies that want to utilize the furnace as baseload year-round. The flexibility in load is also seen as an important factor in connection with the increased use of solar heaters especially in the Danish district heating sector.
Test are being done in Soenderborg plant in order to demonstrate the flexibility and to document the advantage of having an easy controllable process with limited use of back up boilers.
Expected potential impact:
Dall Energy has as part of their internationalization strategy been in contact with a long range of potential cooperation partners in order to test the commercial hypothesis.
Initial agreement is made with one Chinese, and three European companies, who have all visited the Dall Energy plant in Soenderborg, Denmark. An American cooperation possibility is also under development together with a Finnish company located in Montreal.
However, the nature of the biomass heating area is characterized by a long development time due to a difficult decision-making and purchasing process and in many cases a difficult local project approval practice.
Nevertheless, customization of the Dall Energy technology has been initiated in cooperation with the partners in order to bring the technology to the marked.
The customization is split in two groups:
1. Customized in order to serve a specific industrial process
2. Customized in order to simplify design and reduce cost
Cooperation strategy and project possibilities has been discussed and initial agreement about project development has been initiated with the following named turnkey partner:
1. Dalkia (France) – Projects in France
2. Semco (Denmark) – Projects in Guatemala
3. Envirotherm (Germany) – Projects in Germany
4. Great Resources CORP.PLC (China) – Projects in China
5. Pöyry (Montreal) Inc. – Projects in US
