Ventilatorenfabrik Oelde GmbH extends the lifetime of the refractory brick lining in kilns in the cement industry – by targeted cooling of the surface of rotary kilns.
During clinker production the kiln shell is subject to process-related high temperatures. The increasing use of secondary fuels, resulting in temperature changes in the kiln, affect the useful life of the refractory brick lining and can cause unwelcome stoppages. The result: production losses and repair costs.
