This project will focus on the
Standardisation of the Guideline for the measurement of organic contaminant
(called 'tar'). This Standard provides a set of procedures for the measurement
of organic contaminants and particles in producer gases from biomass gasifiers.
The procedures are designed to cover different gasifier types (updraft or
downdraft fixed bed or fluidised bed gasifiers), operating conditions (0
- 900°C and 0.6 - 60 bars) and concentration ranges (1 mg/mn3 to
Although several institutes have now used the Guideline,
it does not have the status of an international standard yet. The overall
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.
