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 >
