Reasons for ESP conversions & retrofitsReasons for ESP conversions & retrofits

Stricter emission regulation by the authorities

Use of secondary fuelsUse of secondary fuels

Reduction of operation costs

6

Advantages of Intensiv-Filter bag filters (versus ESP’s)Advantages of Intensiv-Filter bag filters (versus ESP s)

Lower and constant clean gas dust emissions for the use of secondary fuels as kiln fuel to meet strict authority regulations

Performance is independent on changing parameters and operating modes (e.g. compound & direct mode)

Precipitation is not pending on moisture and chemistry of the gas & dust

No CO – trips for kiln dedusting applications

Online Maintenance possibilities and easy maintenance access (from the clean gas side)

Benefits for ESP conversions & retrofits made by Intensiv-FilterBenefits for ESP conversions & retrofits made by Intensiv-Filter

Lower clean gas dust emissions (constantly) compared to the ESP operationE i l b filt d i i l ff li l i iEconomical bag filter design using low pressure off-line cleaning incombination with bag length up to 8m can be foreseen for ESPconversions, to decrease the pressure drop across the bag filter and to increase the bag life timeto increase the bag life time. Re-use of existing casing, duct work, steel support, dust transportand auxiliary equipment y q pFlexible and pre-assembled filter head module design reduces downtime to a minimum and enables the plant to execute ESP conversionsduring regular plant shutdown timesduring regular plant shutdown timesLow cost solution (compared to a new installation)
