    • Improving the environmental safety of ash from bioenergy production plants 

      Soininen, Hanne
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 14.12.2018)
      Each year, energy production plants in Eastern Finland produce just under 100,000 tonnes of different types of ash and slag in the process of energy production. The utilisation of energy production ash flows has made ...
    • International trade in biomass for energy production: The local and global context 

      Proskurina, Svetlana
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 31.08.2018)
      Biomass is an important source of renewable energy in the global energy mix. International trade in biomass is increasing. It is stimulating global use of biomass for energy and promoting development of bioenergy in many ...
    • Losses in low-Reynolds-number centrifugal compressors 

      Tiainen, Jonna
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 2018)
      Micro-scale centrifugal compressors and compressors operating at a high altitude suffer from performance deterioration due to low Reynolds numbers. An improvement in the efficiency of a low-Reynolds-number centrifugal ...
