Coal-fired power plants burn coal dust at temperatures exceeding 1200°C. The process also melts the mineral components of the coal. The result is pulverised fuel ash or fly ash. These solid dust grains, which consist mainly of silicon, aluminium and iron oxides, are separated from the smoke gas flow in cyclones by means of centrifugal force. The impact speed and mass of the highly abrasive material cause significant wear, especially in the infeed area, cylinder, basin and cone of the cyclone. Effective wear protection significantly increases the service life of plant components.
Kalenborner wear protection solutions are also used in applications one would not necessarily think of, for instance in wastewater treatment plants. During the treatment process, many kinds of solid matter are removed that can cause considerable wear to the plant. KALCRET is the remedy.
