Fusion characteristics in c o-combustion of coal with industrial and municipal sludge
摘要
Abstract
The ash fusion characteristics of coal mixed with different kinds of sludge were investigated.Mineral ternary phase diagram and XRD analysis were used to identify interaction mechanism of different mineral components and transformation of ash melting characteristics during burning ofc oal with municipal and industrila sludge.The results show ht at ternary phase diagram can effectively predict the variation of ash melting temperature for co-combustion of coal and sludge.When the content of iron oxide is low, the formation of etu ectic, diopside and anorthite canr educe the ash fusion temperature.Monticellite, mullite and monomer form of iron oxide improve the ash fusion temperature.The sulfur in municipal sludge easily forms low temperature ue tectic of sulfate.Teh influence of phosphorus on the ash fusion temperature is related to the ar tioo f alumina and alkali.When the alumi na is dominant, ph osphorus will reduce the ash uf sion temperature.When the alkali is primary, phosphorus will raise the ash fusion temperature.关键词
