本文研究了我国煤灰渣在1100—1750℃条件下,10—500泊范围内的流动特性,以及煤灰渣的流动性和灰熔点、灰成分的关系。提出了临界粘度温度和软化温度的线性相关方程式,给出了50、100和250泊粘度下的温度与当量二氧化硅百分率及碱酸比的关系曲线,为选择液态排渣炉用煤和以添加助熔剂或配煤方法来改变灰渣流动性提供了依据。 In this paper, the flow characteristics of coal ash slag at a temperature of 1100-1750°C, 10-500 poise, and the relationship between coal ash slag fluidity, ash melting point and ash composition are studied. A linear correlation equation of the critical viscosity temperature and the softening temperature is proposed, and the curves of the temperature, the equivalent silica percentage, and the ratio of alkali acid at 50, 100, and 250 poise viscosity are given. The liquid slagging furnace coal and the Adding flux or coal blending method to change the flow of ash provides a basis.
