In this study, based on CFD (LES-DPM) numerical simulations, a quantitative method, which identifies heat-release cores and employs a coefficient of variation to evaluate their spatial continuity, was developed to describe the flame evolution process and assess the combustion stability of pulverized coal jets. The combustion characteristics were investigated under varying coal feed and air supply rates, and the instability mechanism under low-load conditions was emphatically discussed. It was found that the essence of stable pulverized coal jet combustion is to form the continuous high-intensity heat release regions, namely the heat-release cores in jets and the formation, merging, and fragmentation of heat-release cores, are closely affected by the gas-solid diffusion and the mixing of fuel and oxidant. Under low-load conditions, the reduced coal feed rates and air supply with the weak gas-solid turbulence lead to the non-homogeneous fuel and heat distribution in the jet space. The heat-release cores fail to merge and the flame shows significant spatiotemporal fluctuations.

This study presents an interpretable machine learning framework that leverages SHapley Additive exPlanations (SHAP) to investigate the influence of parameter interactions on concentrate grade and recovery. Predictive models were developed using key operational factors, including drum rotation speed, drum–tank distance, PLIMS inclination, magnet assembly inclination, particle size, and pulp density. Four machine learning algorithms, namely, random forest regression (RFR), gradient boosting regression (GBR), extreme gradient boosting (XGBR), and light gradient boosting machine (LGBR), were systematically optimized via Bayesian hyperparameter tuning and K-fold cross-validation. Model performance was evaluated using mean squared error (MSE) and Nash–Sutcliffe efficiency (NSE). GBR outperformed all other models, achieving NSE scores of 0.9582 (grade) and 0.9602 (recovery). Subsequently, SHAP analysis was applied to interpret the GBR model. The results revealed that particle size exerted the greatest influence on concentrate grade, while drum–tank distance emerged as the most critical factor for recovery. Furthermore, two-feature interaction effects were explored through SHAP dependence plots, and SHAP waterfall diagrams were employed to visualize prediction mechanisms under different parameter combinations.
