灰中酸性成分对灰熔融温度的影响
Effect of acidic compositions on ash fusion temperatures
摘要
Abstract
Ash fusion characteristic parameters of 129 typical original ash samples were collected locally andabroad , which included coals, sewage sludge and blends of sewage sludge / coal. These data were used to study the effect of acidic oxides including SiO 2 , Al2 O3 , TiO2 and P2 O5 on ash fusion temperatures ( AFTs). The refractory minerals such as quartz, metakaolin, mullite and rutile formed by SiO2 , Al2 O3 and TiO2 improve the AFTs. The results show that Al 2 O 3 is a main factor in determining AFTs. Furthermore, the non-metal oxides P 2 O 5 has a significant correlation with the FT of sewage sludge and sewage sludge / coal blends and its increase can obviously reduce AFTs, which might be caused by the higher P2 O5 content in sewage sludge.关键词
