Summary: This paper studies the radiative energy characteristics of oxy-fuel combustion of pulverized coal, focusing on spectral distribution characteristics. Experimental results show that the intensity of radiative energy and exergy increase with oxygen ratio and combustion temperature, while different atmospheres have little effect on radiation characteristics. One-dimensional calculation can better reveal proportional characteristics of spectral radiation.

Summary: This work provides a complete exergy analysis of municipal solid waste incineration process, with considerations on increasing O2 %mol and adopting oxy-combustion conditions. Flue gas recirculation and oxygen-enriched air were found to improve exergy efficiency and reduce environmental impact. However, limited exergetic improvements were observed due to the exergy cost of the air separation unit.

Summary: With over 150 billion m(3) of gases flared annually worldwide, gas flaring is a major source of greenhouse gas emissions, contaminating the environment with over 400 Mt CO2/year. Utilizing flared gases efficiently is crucial, and one promising technology is Gas-to-Power (GTP). Using direct oxy-combustion (DOC) supercritical CO2 (sCO2) power cycle can achieve the desired no flaring-no emissions solution.

Summary: This paper investigates the near-field thermo-photovoltaics (NFTPV) system from the energy perspective and proposes a novel oxy-enrich NFTPV system. A thermo-physical model is established for sustainable fuel gas based on energy balance. Numerical analysis is conducted to explore the effects of various parameters on system performance. The results show that the oxy-enrich NFTPV system has higher efficiency and power density compared to the far-field TPV system, which is significant in engineering practice.

Summary: This paper introduces a procedure for detecting the sources of industrial noise and evaluating their distances based on analysis of acoustic and optical data recorded by an acoustic camera. Interpolation and quasi interpolation algorithms such as bilinear, bicubic, and sampling Kantorovich (SK) are used to improve data resolution, with experimental tests demonstrating that the SK algorithm performs the task more accurately than other methods considered.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
