Efficient boiler cleaning with Shock Pulse Generators
With proven online cleaning technology, deposits on heat exchanger surfaces, e.g. membrane walls and tube bundles, can be successfully prevented in large boiler plants. In retrofit projects, the deposits can be significantly reduced. This innovative Shock Pulse Technology enables you to achieve longer operating periods, higher boiler availability and a reduction in maintenance and operating costs.
More than 1,000 installed Shock Pulse Generators (SPG) are keeping critical boiler areas permanently clean, for multiple fuels like municipal solid waste, industrial waste and coal, as well as in process plants. Waste, industrial, coal-fired power plants and process plants permanently clean.
SPG technology
The Shock Pulse Generator (SPG), developed and manufactured by Swiss company Explosion Power GmbH, is an online boiler cleaning equipment automatically generating Shock Pulses (SP) by pressurised gas combustion. The innovative technology has proven its outstanding performance at worldwide with over 1,000 different installations in 20+ countries since 2009. Plant operators confirmed significant prolongation of boiler operating periods and increased efficiency, thus contributing to a sustainable and economic plant operation. Leading plant suppliers decided to apply SPG-technology to new build plants, additionally profiting from the sophisticated system design and the compact geometry.
SPGr-series
Our product series, the Shock Pulse Generator SPGr, revolutionises automated industrial boiler cleaning. The innovative further development of existing technology enables even higher cleaning performance with reduced maintenance and space requirements. This effectively meets customer requirements for high plant efficiency and sustainability.
