“…However, these operational changes can lead to increased coal consumption, reduced energy efficiency, but also offer significant energy-saving potential. In the era of energy conservation and emission reduction, combustion optimization has become a primary means of regulation [1]. Yet, the intricate nonlinear, time-varying, and coupled nature of combustion processes poses a formidable challenge for predicting and controlling boiler combustion efficiency [2][3][4].…”

“…Micro gas turbines are an integral component of distributed power generation systems and have been extensively adopted worldwide [ 1 ]. However, the combustion of fossil fuels in micro gas turbines produces substantial nitrogen oxide (NOx) emissions, which have contributed to environmental degradation since the onset of industrialization [ 2 , 3 , 4 ]. Excessive NOx emissions not only pose a threat to human health by causing respiratory disease, but also damage vegetation and buildings by triggering the formation of acid rain [ 5 ].…”

Micro gas turbines are widely used in distributed power generation systems. However, the combustion of gas turbine combustors produces a large amount of nitrogen oxides (NOx), which pollute the environment and endanger human life. To reduce environmental pollution, low-emission combustors have been developed. In recent years, there has been an increasing focus on the use of low-heat-value gas fuels, and it is necessary to study the NOx emissions from low heat value gas fuel combustors. Data-driven deep learning methods have been used in many fields in recent years. In this study, a variational autoencoder was introduced for the prediction of NOx production inside the combustor. The combustor used was a micro rich–quench–lean combustor designed by the research group using coal bed gas as a fuel. The internal NO distribution contour was obtained as the dataset using simulation methods, with a size of 60 images. The model architecture parameters were obtained through hyperparameter exploration using the grid search method. The model accurately predicted the distribution of NO inside the combustor. The method can be applied in the prediction of a wider range of parameters and offers a new way of designing combustors for the power industry.

“…They come from vehicle exhaust, fuel combustion, and industrial emissions, such as nitrogen fertilizer production, ferrous metal smelting, and others. [1][2][3][4] They are harmful to the environment and industrial equipment, leading to acid rain and equipment corrosion. [5] Thus, it is meaningful to control NOx from the industrial tail gas.…”

Catalytic oxidation of nitric oxide over modified carbide slag: Experimental and theoretical studies

In this work, experimental and theoretical methods were used to investigate the catalytic effect of K 2 O on NO oxidation. Experimental results indicated that K 2 O was the main active component. It enhanced the removal of NO and decreased the reaction temperature. Theoretical results indicated that the K 2 O (001)-O surface was more suitable for the adsorption of NO and O 2 . Also, NO and O 2 on the Ca(OH) 2 surface may migrate to the K 2 O surface for reaction.NO 2 was formed via the interaction of (NO) 2 and O atoms. The formation of O N N O was the key step for NO oxidation, which was more conducive to the subsequent oxidation of NO.
