Hardly any other process makes such different and changing demands on a filter medium as the process of lime burning. Again and again, the diverse types of kiln, fluctuating temperatures, various fuels and frequent passing through the dew point present a challenge when choosing filter media.
The burning process can be done in a:
|Case history: Lime - fluidised-bed kiln||Case study: Lime - shaft kiln|
|Filtering area||300 m²||1.950 m²|
|A/C||0,85 m/min||1,15 m/min|
|Dust load||50 g/Nm³||5 g/Nm³|
|240°, peaks up to 270°C||120 - 180 °C|
|Filter media||Fibreglass with ePTFE membrane||NX needlefelt|
