Summary: The article presents the results of experiments on adding sulphide based additives to the CaCO3 slurry in Wet Flue Gas Desulphurization plant (WFGD), both in laboratory and full-scale. Full-scale tests were conducted on two WFGD installations that clean flue gas from burning hard coal and lignite. The study investigated the effects of sodium sulphide addition to the CaCO3 slurry on reducing mercury emissions and precipitation of heavy metals. The results show significant reduction of mercury emissions (up to 89% for hard coal and 90% for lignite) and decrease in heavy metal concentration in wastewater (with mercury precipitation efficiency reaching 88% for lignite and 83% for hard coal).

Summary: In this study, the potential of Refuse Derived Fuel (RDF) in Poland was investigated, revealing significant limitations due to its high heterogeneity and contamination. Samples of fuel and fly ashes were analyzed to determine their composition and characteristics, while the impact of flue gas treatment on ash morphology and composition was also studied.

Summary: Heavy metals can impact fetal neurodevelopmental processes by crossing the placental and blood brain barriers. This study measured metal levels in cord blood and serum samples of children with and without ASD. The results suggest that prenatal aluminum levels may indicate later ASD incidence, potentially related to increased exposure to aluminum and lithium during pregnancy, while zinc exposure during pregnancy may be higher in controls. Additionally, there is strong evidence of increased mercury levels in 5-year-old children with ASD compared to controls.

Summary: This paper presents the importance of waste combustion/co-combustion by conducting tests on fuels of different compositions. The authors analyze the materials and ashes, as well as the mercury content in them, and find that coke waste and sewage sludge have high mercury content. The addition of a polymer to coal fuels reduces mercury emissions in exhaust gases.

Summary: The study shows that the fuel split device (FSD) can improve fuel/air mixing process by splitting fuel spray, increasing air utilization and enhancing combustion efficiency. The FSD expands fuel injection area and forms multi-vortex structure, resulting in improved fuel/air mixing process and reduced emissions.

Summary: The galvanic reaction between graphene quantum dot (GQD)-stabilized silver nanoparticles (AgNP)-modified glassy carbon (GC) surface and Hg(II) leads to the complete dissolution of AgNPs within 15 minutes and the subsequent growth of Hg(0) as a flower on the GQD surface. This unique anti-amalgamation reaction is caused by direct deposition of Hg(0) by available oxygen functional groups and strong adsorption on the GQD graphene surface, followed by subsequent growth of Hg(0) as a flower due to the galvanic reaction between AgNPs and Hg(II).

Summary: This study examines the influence of biohydrogen gas on the emissions and performance of a diesel engine. The results show that adding biohydrogen gas can reduce the concentrations of CO, CO2, and NOx in the exhaust, while increasing the brake thermal efficiency and heat release rate of the engine. However, the brake specific fuel consumption is higher due to energy discrepancy.

Summary: This study focuses on the combustion characteristics of biogas under different oxidizers in a swirl combustor. The results show similar trends in temperature distributions between experimental measurements and numerical predictions when using different oxidizers. Combustion using 100% O2 is found to have higher temperature values, starting faster and more efficiently.

Summary: The study investigated the residual and ecological risks of heavy metals in fly ash from co-combustion of municipal excess sludge (ES) and coal. It found that Cu, Zn, and Mn had higher concentrations in the fly ash and most heavy metals were concentrated in fine particles. Despite lower concentration, Cd accounted for the main fraction of ecological risk in the fly ash.
