Résumé des résultats (Abstract) (Anglais)

In biomass gasification based CHP (combined heat and power) systems, contaminants can, if not removed, damage the engine or turbine or incur an unacceptable level of maintenance. For most contaminants, well -developed and standardised measurement techniques exist, which allow to determine the gas cleaning performance and to assess the clean gas quality. For 'tars' this is not the case and different sampling and analysis methods are currently being used. Therefore, in a previous EU project, a Guideline for tar measurement ('the Guideline') was developed. Although several institutes have now used this Guideline, it does not have the status of an international standard yet. The objective of the project is to remove this obstacle by standardising the Guideline. The result will be a CEN Standard. As acceptance and use by others is considered to be essential, dissemination and internalisation of the Standard forms part of this project.

Measurement methods and definitions for organic contaminants in biomass gasification based CHP-systems are numerous and non-uniform. So, comparison of data and definition of maximum allowable concentrations for the contaminants is problematic. This is an obstacle for market introduction of CHP systems as the contaminants can cause damage or an unacceptable level of maintenance. Therefore, in a previous EU project, a Guideline for tar measurement ('the Guideline') was developed. Although several institutes have now used this Guideline, it does not have the status of an international standard yet. The objective of this project is to remove this obstacle by standardising the Guideline. The result will be a CEN Standard. As acceptance and use by others is considered to be essential, dissemination and internalisation of the Standard forms part of this project.
