利用测定粘附温度的方法，研究了煤灰掺入生料后，生料在耐火砖上粘附温度的变化，得出了煤灰的掺入量与粘附温度之间的关系。研究结果表明：煤灰掺入后粘附温度降低，从而促进旋风预热器结皮堵塞。 By measuring the adhesion temperature, the change of the adhering temperature of the raw material on the refractory brick after the coal ash was mixed into the raw material was studied, and the relation between the amount of the coal ash and the adhering temperature was obtained. The results show that the adhesion temperature of coal ash decreases, which will lead to clogging of the cyclone preheater skin.
