Coal refinement with remote-head metering pumps in condensing systems
In process engineering, various tasks include the metering and circulation of media with critical properties such as high temperature or high abrasiveness. For the injection of coal slurry in coal conversion plants, coal is ground to dust and mixed with oil or solvent to produce a suspension which is usually abrasive and very hot. Regular metering pumps, due to their compact design, are not suitable for such tasks because they can’t keep away the critical conditions from the metering pumps’ displacer system.
However, exactly this is necessary in order to meter the fluid safely as well as protect operating personnel and the system. LEWA metering pumps with remote head are used in these applications because their design separates valve head from pump drive.
