Aurubis Group operates six smelter sites for copper processing in different locations. Aurubis Bulgaria in Pirdop operates the largest smelting furnace of Aurubis Group. It processes copper concentrates. The off-gas leaving the flash smelter is sent to a waste heat boiler for heat recovery. Due to the high load of fly ash and sulfur dioxide, the waste heat boiler faced severe fouling. The originally designed boiler cleaning system didn’t satisfactorily clean-off the fly ash deposits. Thanks to the implementation of four Shock Pulse Generators delivered by Explosion Power GmbH, the removal of boiler deposits was significantly improved since 2016, enabling a production capacity increase of the flash smelter by over 20%. Two additional SPGs have been commissioned in January 2022 to boost the removal of accumulations in the lower part of the boiler. The operators are very satisfied with the operation of the SGPs and with the entire success of the improvements.

In the fall of 2020, Explosion Power GmbH launched the Shock Pulse Generator SPGr series. With this innovative further development of the existing technology for automated industrial boiler cleaning, Explosion Power GmbH was able to introduce a product series that enables even higher cleaning performance with reduced maintenance and space requirements. These product advantages already led to a considerable number of orders in 2021 and to a lot of positive feedback from customers after commissioning of the new SPGr.

The final test procedure of the Shock Pulse Generators from Explosion Power GmbH ensures a safe and smooth commissioning. In the final test facility, each Shock Pulse Generator is tested for functionality by an expert employee before delivery and the quality is certified.

In 2021, WtE Buchs (belonging to VfA - Verein für Abfallbeseitigung) celebrates the sixtieth anniversary of its founding. Little remains of the original concept of waste disposal.

In the cleaning of soot and fly ash from the combustion plants, much has changed in the history. While the ancestors had to deal mainly with soot in the flue gas, the present-day furnaces are mainly confronted with fly ash in the flue gas thanks to the controlled firing. The «soot», resulting from insufficient combustion is not known to modern combustion technology, because this organic carbon content is burned out to the state of inorganic residue, namely to the fly ash.

A waste incineration plant uses the energy contained in waste to produce steam, which in turn is advantageously converted into electrical energy.
