Abstract Catalytic combustion can inhibit the formation of CO and NOx, and greatly reduce the concentration of unburned alkanes. The hardness of tap water in Beijing is too high. In order to test whether the modified fly ash can reduce its hardness, clay, shale and fly ash bricks were prepared by catalytic combustion furnace. The results show that the fly ash brick has a great influence on Ca²⁺ and Mg²⁺ in water, increasing Ca²⁺ concentration by 59.96% and decreasing Mg²⁺ concentration by 41.22%. Thus modified fly ash could not reduce hardness of water but could be used as an Mg²⁺ adsorbent. More >

Abstract The further development of catalytic elements has been plagued by activation and binary problems. The automatic shift model that has emerged in recent years helps components achieve full range. However, the detection data still remains unstable in the shift area (7%~13%). This paper proposes a Catalytic Combustion and Thermal Conductivity (CCTC) model for the specified range, which can be explained from two aspects based on the existing methods. On the one hand, it uses iterative location search to process heterogeneous data, judges the prediction position of data points, and then gives weight evaluation. On the other hand, it corrects the… More >
