本文采用综合热重分析法,在不同升温速率及泥煤不同比例混合条件下,开展造纸污泥、煤及泥煤混合物的燃烧热重实验研究。结果表明,造纸污泥的热重曲线存在3个明显的失重区域,分别与两个挥发分析出阶段和一个固定碳燃烧阶段相对应。
本文採用綜閤熱重分析法,在不同升溫速率及泥煤不同比例混閤條件下,開展造紙汙泥、煤及泥煤混閤物的燃燒熱重實驗研究。結果錶明,造紙汙泥的熱重麯線存在3箇明顯的失重區域,分彆與兩箇揮髮分析齣階段和一箇固定碳燃燒階段相對應。

The combustion characteristics of paper mill sludge, coal and their blends with different proportions were studied by thermogravimetric analysis(TG-DTG) at different heating rates. The results showed that there were obviously three temperature zones in the paper mill sludge combustion curvescorresponding to two stages of devolatilizations and fixed carbon combustion, respectively, where the weight of sludge was lost promptly.
