Abstract

One way to increase the share of biomass in the energy matrix, and reduce the greenhouse gas and emissions of SOx from fossil-fuel combustion, would be through its co-combustion with mineral coal. However, biomass has very distinct properties from mineral coal, and pyrolysis is a technique that has been studied to improve the performance of biomass in existing coal-fired power stations. A detailed investigation was conducted about the structural changes of a char produced from slow pyrolysis of biomass and of a high-ash coal throughout its combustion process, being assessed its role on reactivity. The kinetics and reactivity were investigated by thermal analysis (TGA/DTG), while structural changes were evaluated in a drop tube furnace (DTF). The biomass char was obtained from slow pyrolysis of Pinus elliottii in a fixed bed reactor at 400 °C with heating rate of 5 °C⋅min−1. Biomass char reactivity was higher than that of coal at low heating rates, and maximum reactivity was observed for both fuels around a conversion of 0.9. A burnout above 90% was obtained for biomass char at 330 ms, while for coal and a biomass char and coal blend (50/50 %wt) such burnout was observed only at 430 ms.
