The acceleration of the use of carbon neutral energy should not lead to deterioration of the air quality or other environmental compartments. Electrostatic filters or catalytic converters are gaining importance for emission control of biogenic solid fuel combustion in small scale units, too. The scientific evaluation of the impact of such flue gas cleaning devices upon the toxicological potential of the remaining particles is still in its infancy. Potential hazards lie in a drastic reduction of particle sizes, the formation of highly toxic secondary aerosols due to the precipitation mechanism or an increase in the biological availability of potentially hazardous particulate matter components. Potential test systems shall be selected and adapted to the scope of this work. The test systems shall be optimised for maximum sensitivity while the electrostatic filter shall be optimised for minimal toxicity of the cleaned flue gas.
In combustion experiments with modern biogenic solid fuel furnaces samples shall be generated upstream and downstream of emission control units provided by Karl Schräder Nachf. and others. These samples will be subjected to selected microbial test systems by the TUHH and Dr. U. NOACK-LABORATORIEN. Sampling procedures and test systems will evaluated and optimised in the order: loose dust, filter discs and finally exposition system. A thorough validation of the test system will be followed by a round robin. The precipitators will in turn also be optimised for minimal toxicological impact.
