Abstract:

Sewage sludge is a promising fuel to co-combust with biomass fuels with benefits of energy production and reducing of ash related problems. However, the fundamental knowledge on the influence of sewage sludge on biomass thermal degradation behaviors is rare. In this work, a combination of thermogravimetry and evolved gas analysis by mass spectrometry (TG-MS) has been applied to investigate the thermal degradation and kinetics properties of oat straw and bark with and without blending with sewage sludge. The thermal degradation characteristics and the reactivity parameters of the biomass fuels were determined from analysis of thermogravimetric (TG/DTG) curves. Mass spectrometry (MS) was used to measure the gas products distribution and mainly focusing on the release of gas products from co-pyrolysis of two biomass fuels with the studied sewage sludge.
