BIOS has extensive and modern equipment for the performance of test stand and field measurements at combustion, gasification and pyrolysis plants. This equipment includes conventional gas analysis and particle measurement technologies as well as innovative, partly self-developed devices and methods, which are especially used for fly ash, aerosol and deposit sampling, for hot gas measurements (measurements and sampling in reactors at up to 1,200 ° C) and for low temperature corrosion measurements. For measurement data evaluation, special in-house developed software is available.
At BIOS, several test stands for prototypes are available as well as special laboratory reactors for the investigation of the thermal decomposition behaviour of biomass fuels.
Furthermore, BIOS offers chemical and electron microscopy analyses of fuels, ashes, fine particulate matter (aerosols), tars, ash deposits and slags, condensates as well as boiler water, combined with an evaluation of the results.
