摘要(Abstract)：

为了充分利用新疆昌吉地区低热值的油页岩,将油页岩和准东煤进行混合燃烧,利用热重分析仪(TG)、灰熔点测定仪、电感耦合等离子体发射光谱仪(ICP-OES)等手段对其混合燃料的燃烧特性、灰熔点变化及Na的挥发进行充分研究。结果表明:随着灰中碱性氧化物和酸性氧化物质量比(B/A)的降低(油页岩比例升高),混合燃料的着火温度和燃尽温度逐渐升高,可燃性和燃烧特性降低;随着B/A的降低,混合燃料的灰熔点先下降后上升,当B/A为1.67时,灰中各组分比例正好位于低温共融区域,导致灰熔点降低;随着B/A的降低,Na元素的挥发呈先快速下降后缓慢上升的趋势,当燃烧温度为850℃、B/A为1.44时,Na挥发降至最低;油页岩可将煤中的Na固定至灰中,有效地抑制了Na挥发,为油页岩的高效利用提供了新途径。
