• The status of large scale biomass firing – The milling and combustion of biomass materials in large pulverised coal boilers

  Mar 2016

  This IEA Bioenergy Task 32 report provides an overview of the current status of biomass cofiring. The report shows that the firing and co-firing of biomass as a replacement for coal in large pulverised coal boilers can be a very attractive option for the utilisation of biomass materials for power production, and for the delivery […]

• Techno-economic evaluation of selected decentralised CHP applications based on biomass combustion with steam turbine and ORC processes

  Dec 2015

  This report provides an evaluation of the techno-economic performance of three types of biomass combustion based CHP systems, varying from 130 kWe to 5,7 MWe. The report describes three case studies that represent the most relevant small-scale CHP technologies based on biomass combustion relevant for the market at present. It points out the differences between […]

• Status Report on District Heating Systems in IEA Countries

  Dec 2014

  The study presents an evaluation of district heating systems in IEA countries based on characteristic parameters such as the annual heat losses, the linear heat density in MWh/(a m) (where 1 m refers to the length of the pipeline), and the connection load. Data are available and presented for Austria, Denmark, Finland, Germany, and Switzerland […]

• Sensitivity of System Design on Heat Distribution Cost in District Heating

  Dec 2014

  District heating (DH) offers interesting opportunities to use biomass and/or waste heat as an energy source for thermal heat and thus to replace decentralised fossil heating. On the other hand however, district heating induces additional cost and energy losses in the heat distribution. The present project introduces a sensitivity analysis for a virtual DH network […]

• Options for increased utilization of ash from biomass combustion and co-firing

  Mar 2012

  The current study shows that the main reasons for this situation relate to environment, sustainability, low market volumes and differences and variations in ash quality. In addition, there are limitations in technical and regulatory regulations as well as logistics. Finally, there is a lack of awareness, knowledge and willingness of plant operators, potential end-users and […]
