Brown coal dust as fuel

BROWN COAL DUST: SOLID FUEL THAT IS ALMOST LIQUID

Lusatian brown coal dust is a modern energy source for boilers and incineration facilities. The properties of this highly refined, fine-grain fuel are similar to those of liquids. Brown coal dust finds extensive use and is easy to handle.



High quality, high heating value and fluidity: brown coal dust combines the advantages of brown coal with the convenience of liquid fuel.


Lusatian brown coal dust has a high heating value and a naturally low content of sulphur and ash. Good fluidity and easy fluidisation of brown coal dust allow for comfortable use, similarly to oil. Its large active surface and high content of volatile constituents provide excellent flammability, high reactivity and first-class burning properties.

In order to produce brown coal dust, brown coal from the Lusatian mining district is crushed, dried, filtered and ground in Germany’s state-of-the-art refining facility. Strict quality management – covering all aspects from raw materials to production and logistics – ensures consistently high quality of fuel.
The presence in the Schwarze Pumpe energy district is one of Vattenfall’s great strengths: the mining of raw materials, generation of electricity, production of fuel and technological research are closely related activities that result in effective and environmentally friendly value creation chains.
