In Germany, waste wood can be used in various ways. The main ones are recycling in particleboards and energy production if the quality is insufficient for material utilisation. For the decision of usage, it is necessary to determine the wood quality by measuring the concentrations of certain pollutants. If given legal limits are exceeded, energetic...

Particulate matter emissions are a key issue of modern biomass boilers. A novel gas cleaning method using a metal mesh filter combined with water-based cleaning was developed and tested. The filter was tested batch-wise. Flue gas of a commercial 50-kW boiler was filtered until a pressure drop of 2000 Pa was reached. Afterwards, the filter was regen...

To achieve a sustainable circular economy for wood ash, the reuse of wood ash in agriculture and forestry is important. To evaluate the usability of ash from the combustion of natural as well as waste wood for application as fertilizer, wood fuel and corresponding ash fraction samples (n = 86) of four industrial wood-fired heat and power plants (>2...

Wood combustion is a major part of the current efforts to reduce CO 2 emissions. However, wood combustion leads to emissions of other pollutants like fine particulate matter. A new option to reduce particulate matter emissions is a metal mesh filter with counter current flushing. An automatic prototype was tested under realistic conditions includin...

In order to design and optimize furnaces, modelling is a key tool. Modelling of solid fuel conversion requires the availability of valid kinetic data for the parametrization of combustion models. In order to provide kinetic data for low temperature devolatilization, 1 g of wood dust (oak and spruce) was devolatilized under isothermal conditions at...
