Sustainable biomass technology

Technologies

Dall Energy´s products are based on our own technologies which were developed, refined and patented over the past few decades.

Due to very low dust emission from the Dall Energy furnace our heating plants do not need bagfilters or an electro filter in that the flue gas condenser provides sufficient particle removal. The table below provides an overview of our furnace performance compared to a traditional grate solution and the European air emissions requirements.

Air Emissions


 Dust [mg/Nm3] (in EU)


 NOx [mg/Nm3] (in EU)


CO [mg/Nm3] (in Denmark):


100 % Load


10 % Load


Required by Law


 30


300



850


850


Typical grate solution


 500 – 1000 out of furnace, or

100 – 125 with flue gas cond.


 200-300



< 600


Operation not possible


Dall Energy solution


30 – 60 out of furnace, or

10 – 20 with flue gas cond.


100-200 



< 10


< 20


The air emissions requirements above are based on EU Directive 2015/2193 of November 25, 2015 (the EU MCP Directive) and requirements are defined at 273.15 K, 101.3 kPa and 6% O2 dry basis. Requirements for CO differ in the individual EU countries and we have thus stated the Danish limits.

In the city of Bogense 6,000 people get their heating from a special biomass oven. They are warmed by that. And I am warmed by the fact that the inventor of the oven has been awarded the European Inventor Award...”
