摘　　要：结合国标中对灰样制备试验条件的相关规定,选取煤样摊铺厚度、升温程序、煤样单烧和混烧等对煤灰中三氧化硫测值的影响进行试验研究,以确认灰样制备对保证灰成分中三氧化硫测定结果准确的重要性。Combining with the relevant provisions of ash sample preparation experimental conditions in the national standard, in this paper, aspects like the thickness of the coal sample, the heating process, the coal sample separately burning and mixing burning were selected, to research their influence on the determination value of sulfur trioxide in coal ash, the importance of ash sample preparation in ensuring the accuracy of determination of sulfur trioxide in ash composition could be confirmed.

关 键 词：灰样制备 三氧化硫 试验条件 煤灰成分分析 升温程序 快速灰化法 缓慢灰化法
