SO2 and NO emissions during combustion of high-alkali coal over a wide temperature range: Effect of Na species and contents

Zhikun Zhang et al.

Summary: This study investigated the effects of alkali species and contents on SO2 and NO emissions during the combustion of high-alkali coal. The results showed that the addition of NaCl and Na2CO3 significantly reduced the emissions and shifted the maximum emission temperatures to lower temperatures. Additionally, sodium showed enhanced suppression effects on SO2 and NO emissions with increasing loading amount, but the suppression effect on SO2 decreased at high temperatures.

Different carbon treatments for steel slag powder and their subsequent effects on properties of cement-based materials

Yafeng Rui et al.

Summary: This study investigates the use of bacteria and steel slag powder for fixing CO2. The results show significant differences in the physicochemical properties of steel slag powder with different treatments. Cement-based materials mixed with bacteria-treated steel slag powder exhibit better mechanical properties.

A novel direct reduction-flash smelting separation process of treating high phosphorous iron ore fines

Qipeng Bao et al.

Summary: This paper introduces a new process for treating high phosphorus iron ore, which involves studying the effects of flash smelting temperature and ore particle size on the flash smelting process. By limiting the smelting separation time between slag and iron, the migration of phosphorus is constrained, resulting in controlled phosphorus content in the metallic iron obtained after separation.
