文章指出用灰溶点,灰渣粘度,烧结特性和按灰成分计算的沾污、结焦指数等方法来判断炉内结焦倾向,往往造成误判断和没有说服力。主要原因有二:其一是在800℃左右制取灰样时,原煤中的矿相体已被破坏和分解;其二是试验室的测量条件与粒子在 The article points out that using the ash melting point, the ash viscosity, the sintering characteristics and the calculation of the ash content by the ash composition, the coking index and other methods to determine the tendency of the furnace coking tend to cause misjudgment and persuasion. There are two main reasons: First, when the ash sample is prepared at about 800 ℃, the ore body in the raw coal has been destroyed and decomposed; secondly, the measurement conditions of the laboratory and the particles in the
