“…Normally, raw sewage sludge has a moisture content of approximately 90%. The H, N and S contents are comparable to other studied sewage sludge samples [2,6]. The presented sewage sludge has "good fuel properties" and can be successfully used as a fuel for the combustion process.…”

Abstract. The ashes from sewage sludge combustion in air versus O2/CO2 atmospheres with oxygen concentrations in the range of 21-40% vol. at temperature of 850°C in a 12 kW bench-scale CFB combustor were characterised. The chemical and phase composition of ashes were studied by XRF and XRD. The morphology of studied ashes were examined by SEM method. The slagging and fouling indices were calculated to study the deposition tendencies of ash. The thermal behaviour of ashes was studied by TG-DSC techniques, focusing on the mass loss and thermic effects with the increasing of temperature up to 1200C.

“…There are several thermal technologies for utilising municipal sewage sludge to obtain useful forms of energy, such as pyrolysis, gasification, combustion, and co-combustion processes [1,2]. The combustion processes of sewage sludge and its combustion in relation to coal and biomass fuels and co-combustion are presented in [3][4][5][6].…”

“…Recently published literatures have stated that the co-utilization of sewage sludge with other solid fuels may be feasible from the energetic and environmental points of view, especially when it is implemented in existing infrastructures [4][5][6][7]. Meanwhile, nearly 154.2 megatons of oil-palm solid wastes were produced during palm oil milling process annually in the worldwide.…”

Two-in-One Fuel Synthetic Bioethanol-Lignin from Lignocellulose with Sewage Sludge and Its Air Pollutants Reduction Effects

et al. 2019

Developing effective, economical, and environmentally sound approaches for sewage sludge management remains an important global issue. In this paper, we propose a bioethanol-lignin (nonfood biomass)-based sewage sludge upgrading process for enhancing the heating value and reducing air pollutants of hybrid sewage sludge fuel (HSF) for the effective management of sewage sludge. Sewage sludge paste with the lignin-CaO solution implies drying at 105 °C accompanied by torrefaction at 250 °C. During torrefaction, moisture and partly volatile matter begin to evaporate, and are almost vaporized out to the surface. In this study, the proposed process enhances the net caloric value (NCV) to 37%. The lignin-embedded HSF shows a two-in-one combustion peak regardless of the mixing ratio, resulting in a 70% reduction of unburned carbon (UBC) emissions, which is one of the particular matter (PM) sources of combustion flue gas. Other air pollutants, such as CO, hydrocarbon, NOx, and SOx, were also reduced by the proposed process. In particular, SOx emission remained at ~1 ppm (average value) regardless of the sulfur content of the fuel.
