title: Co-firing of coal and manure biomass: a TG-MS approach.
abstract: Manure is a rich organic waste which, apart from its traditional use as a fertilizer, could be used as a bioenergy feedstock. In this sense, its utilization as a sole fuel or its co-combustion together with coal would be a choice for the management of this sort of biowaste. However, little is known about the behavior of this biowaste when submitted to high-temperature energy-conversion processes. Thus, the separate combustion of swine manure and coal and their co-combustion (10% dried weight of manure) were studied by simultaneous TG/MS dynamic runs. TG-MS analysis was successfully used as an easy rapid tool to assess the combustion of manure, alone or together with coal. Furthermore, non-isothermal kinetic analysis showed that the Arrhenius activation energy corresponding to the combustion of the blend (125.8-138.9 kJ/mol) was only slightly higher than that of manure (106.4-114.4 kJ/mol) or coal (107.0-119.6 kJ/mol).
