摘要
研究了粉煤灰中游离氧化钙在灰水中的溶出规律,分析了灰水pH、Ca^(2+)及灰中游离氧化钙和CaCO_3含量的变化;指出游离氧化钙的溶出特性是确定灰管结垢程度、灰水pH和选择防垢措施的依据。
This paper researches a law on the dissolve of free calcium-oxidein in ash-water, analyses the changes of pH,Ca^(2+) in ash-water and FCaO,CaCO_3 in ash. It points out that the dissolving character of FCaO is the basis for preventing scale of ash pipes reducing the pH of ash-water, etc.
