Co-combustion of torrefied biomass-plastic waste blends with coal through TGA: Influence of synergistic behaviour

Yogeshwari Pooja Rago et al.

Summary: This study investigated the influence of torrefaction on the combustion performances of biomass-plastic waste blends and found synergistic interactions during co-combustion of the waste blends with coal. The combustion index of the MBr-Np blend was significantly higher than predicted, and the burnout temperatures of all waste-coal blends were lowered. The synergies during co-combustion were governed by the waste type, composition, and interactions during torrefaction.

Influence of biomass thermal pre-treatment on the particulate matter formation during pulverized co-combustion with lignite coal

Duarte Magalhaes et al.

Summary: The study found that co-combustion of thermally pre-treated biomass and coal led to a significant reduction in PM2.5 emissions, approaching levels of biomass fuel, and the mechanisms for PM formation during combustion were found applicable to biomass-coal blends. The shift from fine to coarser particles during co-firing is likely to enable the capture of PM from biomass-coal co-firing by conventional coal-PM traps in existing coal power plants.

An overview of nitrogen oxides emissions from biomass combustion for domestic heat production

S. Ozgen et al.

Summary: To meet the climate and energy objectives of the European Union, the heating and cooling sector needs to reduce its reliance on fossil fuels. Solid biomass is seen as a renewable and carbon-neutral alternative, but there are concerns about its impact on air quality when burned in small-scale domestic appliances, particularly in terms of particulate matter and nitrogen oxides emissions. The focus of this study is to review the literature on nitrogen oxides emissions from these sources, discussing formation mechanisms, control techniques, and the influence of fuel composition and operating conditions gathered from experimental data.

Investigation on combustion, gaseous pollutants emission and ash characteristics during co-combustion of semicoke and coal slime

Ruidong Zhao et al.

Summary: The co-combustion of semicoke and coal slime can improve the ignition and burnout performance of blends, but lead to a decline in the comprehensive combustion index. Adding coal slime can inhibit the co-combustion at the early stage, but promote fixed carbon combustion, while ash accumulation suppresses co-combustion again at the burnout stage.
