Shock Pulse Generators exceed expectations on finned tube ECO cleaning in a biomass boiler

Mirek Spicar |

240.000 Tons of natural wood are being processed each year in the biomass boiler located in Nesle (France), where they are being converted into renewable electricity (130 GWh/year), process heat (220 GWh/year) and cooling water (2 GWh/year). The owner AKUO Energy and the operating company CNIM EB hence contribute since 2013 to a reduction of the CO2-emissions of the local industry.

Top five cleaning technologies to control buildups in radiation passes

Kaspar Ninck |

Maximale thermische Effizienz bei minimaler Korrosion – dies lässt sich nur erreichen, wenn die Rauchgase mit der optimalen Temperatur beim Endüberhitzer ankommen. Mit anderen Worten: Die Abkühlung der Rauchgase in den Strahlungszügen muss konstant und kontrolliert ablaufen (siehe Abbildung 1). Dies gelingt nur, wenn die Ablagerungen an den…

How an intelligent retrofit permanently reduces slag build up in a biomass power plant’s furnace

Dr. Christian Steiner |

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…

Improved boiler efficiency in just a few steps for large industrial boilers

Christian Mosbeck |

Energy demands are increasing while resources are becoming ever more scarce. Alternative fuels are gaining ground but their residue levels are high. Utilizing fuels and energy sources more efficiently is thus become increasingly important. Increasing boiler efficiency [1] not only helps towards protecting the climate, it also helps to lower…
