Loibl delivers to Högdalen in Sweden
Special ash transport. The ash produced by the combustion process is reliably transported away via Loibl equipment. A discharge screw conveyor was installed on the 2nd/3rd boiler pass, which returns the ash to the on-site slag drop shaft. This LASHSCREWCON® including the drop shaft is equipped with a stainless steel contact protection. The fly ash at the horizontal hoist is conveyed via rotary valves as well as a LASHSCREWCON® into a collecting screw. The LASHCHAINCON® at the economizer is designed as a single strand chain conveyor and discharges the accumulating ash in the upper run to the collecting screw. The collection screw was designed with a split trough and screw tree. This specification was adapted to the structural conditions on site and is conducive to changeover as well as dismantling operations. The collection screw discharges into a reversible LASHSCREWCON®, which discharges the ash into an on-site stockpile trough chain conveyor and, in the event of a failure, into an emergency ash removal container.
