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.

Summary: The study investigated the co-combustion of coal with distillery sludge waste (DSW) in a laboratory-scale Drop Tube Furnace (DTF) plant. Preliminary testing methods were used to examine the feasibility of combustion and identify burnout efficiency, emitted pollutants, and metal constituents in the ash. The study showed a high degree of correlation between gaseous emissions, combustion efficiency, and the optimal sludge proportion in the DTF under given combustion conditions.

Summary: This study presents a simple model for simulating combustion processes in a drop tube furnace, which is much simpler than other available models. The model assumes that a coal char particle remains spherical during combustion and is based on two differential equations describing the evolution of particle temperature and oxygen concentration with respect to time. This model also provides access to local quantities to characterize the combustion process, and its validity is demonstrated through comparisons with experimental data.

Summary: Particulate matter emitted during autopsies may act as a medium for the transmission of various viruses or bacteria, leading to infections. Thus, it is crucial to reduce the exposure to these particles in indoor working environments. In this study, particulate matter in the ambient air during autopsies was measured using an aerosol spectrometer. The particle emissions from using an ordinary oscillating saw and an adapted saw with a suction unit were compared to evaluate the effectiveness of technical adaptation in reducing particles. Additionally, the impact of wearing a face mask and variations in room background concentration were analyzed. The results showed high particle concentrations while using the ordinary saw, but the exposure could be mostly avoided by using the adapted saw or wearing a face mask. On most working days, an increase in background concentration was observed. Based on these findings, the use of a proper suction unit and face mask during autopsies is necessary, along with sufficient ventilation to prevent long-lasting high background concentrations.

Summary: This study investigated the association between ambient particulate matter (PM) pollution of different sizes (PM1, PM2.5, and PM10) and the risk of rehospitalization among stroke patients in China. The results showed that higher levels of PM pollution were associated with an increased risk of rehospitalization, and the association was stronger for annual average concentrations compared to seven-day average concentrations. The study also estimated the burden of stroke rehospitalization attributable to PM pollution, and found that it is responsible for a significant proportion of rehospitalization cases and associated costs.

Summary: The study shows that the particle pollution in Hefei can be divided into three stages: accumulation, outbreak, and dissipation. During the outbreak, the particulate matter first appears in the upper part of the boundary layer and then accumulates downward, leading to ground pollution. The increase in particulate matter with a diameter of 0.8-1.6 μm is significant during the outbreak, with smaller particles growing before larger ones. Sulfate particles play a crucial role in the outbreak and dissipation of pollution, and they are the most sensitive factor in the pollution process.

Summary: This paper proposes and studies a piston-type thermally-driven pump with a structure similar to a linear compressor, aiming to eliminate the high-quality energy consumption of existing pumps and replace mechanical pumps. The coupling mechanism of working fluid flow and element dimension is analyzed based on force analysis, and experimental data analysis is used to determine the pump operation stroke. Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
