Status Report on District Heating Systems in IEA Countries
Dec 2014The 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 2014District 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 2012The 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 […]

Factsheet on indirect cofiring
Dec 2009Indirect co-firing consists of the combustion of producer gas from biomass/waste gasification in coal-fired furnaces or lime kilns. Gasification can be thus considered a method for biomass pre-processing. For factsheet click here

Inventory report on aerosols from small scale biomass combustion devices
Jan 2008The objectives of the present study is to review available data on emission factors of particulate emissions from biomass combustion and measurement techniques applied to characterise particle emissions from biomass combustion. Priority is given to wood fuels used in residential wood combustion and in district heating plants. To enable a comparison of different data, the […]
