Lignite - Wholesale

WuW GmbH is a wholesaler and supplier with many years of experience in the sale of coal dust. We buy directly at the colliery (without middlemen). This enables us to offer you the best possible price.

Coal dust is a solid, dusty fuel produced from lignite or hard coal. Since it can be produced from the smallest classification, coal dust is a relatively inexpensive energy source. The decisive advantage of pulverized coal firing is not only its improved efficiency (high burnout of coal, lower excess air), but also the faster controllability of the firing capacity.

A distinction is made between natural coal dust produced during the mining process with a maximum particle diameter of 0.5 mm and artificial coal dust produced in grinding plants. This greatly increases the surface area and guarantees rapid combustion. The hard coal is ground in vertical bowl mills with an outlet grain size of approx. 70 µm. The lignite is ground in vibrating rod and vertical roller mills and the outlet grain size ranges from approx. 90 µm to 500 µm.

Today, coal dust is used for firing in power stations, cement and lime works, as well as drying and asphalt mixing plants and for briquetting (domestic firing).

Analytical values ex works

Lignite energy pulverized (LEP): 

  • calorific value: 22,200 kJ/kg
  • Water content: 11.0
  • Ash: 4.0
  • Carbon: 59.5
  • Hydrogen: 4.3
  • Sulphur: 0.35
  • Nitrogen: 0.7
  • Oxygen: 20.3
  • The data are approximate values

A very important aspect is the fact that due to the high CaO and MgO content of the ash, approx. 50% of the already very low sulphur emissions are incorporated.
