Summary: In this study, an innovative approach combining dielectric barrier discharge (DBD) plasma and fluidized-bed techniques is proposed and employed to remediate atrazine (ATZ) contaminated soil. The fluidized-bed DBD plasma soil remediation system ensures sufficient and uniform contact between the chemically reactive species and the fluidized soil particles, improving the migration and infiltration of reactive species in the soil layer and achieving high-efficiency remediation of contaminated soil. The optimum removal efficiency of 91.2% and energy efficiency of 0.342 mg/kJ were achieved, respectively, after only 6 min fluidized-bed DBD plasma treatment.

Summary: This study investigated corrosion products collected from waterwalls of a circulating fluidized bed boiler. Two types of corrosion spots were identified with high chlorine, potassium, and sodium contents. Laboratory corrosion tests determined the corrosion characteristics and the influence of fuel additives. Halloysite was found to be the most effective additive, and the porosity and adhesion of the oxide layer played a key role in the corrosion process.

Summary: An experimental study was conducted on coal-NH3 co-firing in a pilot-scale circulating fluidized bed combustion test rig. The results showed that injecting NH3 in the dense bed zone reduced NO emissions, while injecting NH3 in the wind box position reduced both NO and CO emissions. However, this co-firing technology increased N2O emissions.

Summary: This study investigates the emission and environmental risks of organic pollutants during co-firing coal liquefaction residue (CLR) in a circulating fluidized bed (CFB) boiler through field tests. The results show that co-firing CLR can reduce coal consumption without significantly affecting combustion parameters. Co-firing CLR does not increase the emission of polycyclic aromatic hydrocarbons (PAHs) compared to pure coal combustion, and fly ash has a higher concentration of PAHs.

Summary: This study investigates the nitrogen and sulfur pollutants generated from co-firing coal and biomass under pressurized oxy-fuel combustion. The results show that increasing combustion pressure and biomass blending ratio can significantly reduce emissions of nitrogen oxides, sulfur dioxide, and carbon monoxide, and improve the sulfur self-retention efficiency. The study also reveals that sulfur self-retention occurs through direct sulfation under the typical operating temperature range. Additionally, the pressurized and co-firing conditions have a synergistic effect on reducing sulfur dioxide emissions.

Among all analyzed Ni@CeO2 catalysts, the Ni@CeO2-0.5 catalyst obtained using 0.5 mmol cerium nitrate achieved the highest amount of H2. The optimal H2 production rate of 730.6 mmol/(h g) was obtained at 700 ℃ with an equivalence ratio (ER) of 0.1.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
