This dataset represents the production of high voltage electricity and district heat in an average combined heat and power lignite power plant. 'Lignite' is used as representant for 'brown coal', which includes sub-bituminous coal and lignite according to the definition of the IEA electricity information 2014. (IEA. 2014. Electricity Information 2014. ISBN 978-92-64-21692-1. International Energy Agency (IEA), Paris Cedex (FR).)
Comments on the inventory data of emissions:
- for the assessment of main characteristics (sulphur and ash content of coal, efficiency of the plant) and CO2 a bottom-up approach has been used. It consists in the collection of information about single plants.
- Halogene emissions have been estimated on the basis of the content of the species in the country-specific coal input mix, assuming average retention rates.
- For CO and particle emissions average values for the former UCTE are included (Union for the Coordination of the Transmission of Electricity, since 2009 replaced by ENTSO-E European Network of Transmission System Operators for Electricity).
- The country specific emissions of N2O depend on the share of DeNOx. - Emissions of trace elements were calculated by means of a formula (CORINAIR) using the ash content in the country-specific coal input mix and average transfer coefficients for coal power plants, taking into account the share of DeSOx installed.
- Emission of uranium and thorium radioactive isotopes were assumed proportional to the corresponding element emitted with particles; the other non-gaseous radioactive isotopes of the uranium and thorium decay chain were assumed proportional to the emitted U-238 or Th-232.
- The emission of gaseous radon and K-40 are taken from the literature.

[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]
