Category: Case study

Based on the good experience with the Shock Pulse Generators for boiler cleaning in the presently decommissioned waste incineration plant Real in Lucerne/CH, the operator of the new built plant Renergia in Perlen has again installed the SPGs of Explosion Power GmbH for cleaning of the first three boiler passes. Such operate to the full satisfaction of the customer since 2015.

Explosion Power GmbH installed 4 TwinL SPGs into a Supercritical Pulverized Coal Boiler 660 MWel capacity which operate successfully in support of boiler cleaning and keeping the required flue gas outlet temperature within design specifications (inlet to SCR catalyst elements). For the next phase the Thai power producer intents to install additional 4 TwinL SPGs for saving feed water and steam and for cycle optimization.

The Silbitz biomass power plant in Thuringia, Germany, produces electricity (5.6 MW) and district heat (3 MW) from waste wood. In order to keep its production competitive, a high degree of availability at the plant is required. This was not satisfactory in Silbitz. The reason was the furnace: Heavy slagging on the walls resulted in short boiler operation periods and frequent downtimes. Since 2011, four shock pulse generators have been cleaning the plant during ongoing operation. This has enabled the amount of slagging to be minimized and boiler operation periods to be lengthened in the long term.
