一、灰渣的分类及其研究概况燃煤产生灰渣的形态与煤的燃烧方式和燃烧温度紧密相关。根据形成条件的不同.灰渣一般可以分成三类,第一类是液态排渣的煤粉炉或旋风炉所形成的煤粒化渣.它一般经历了1600℃以上的高温快升和水淬急冷过程.其中70～80%甚至90%变成了玻璃体并被速冷保存了下来.但采用液态排渣的煤粉炉数量不多;第二类是固态排渣的煤粉炉所形成的粉煤灰渣(粉煤灰约占85%.粉煤渣约占15%),它经历了1100～1500℃的高温快升和空气悬浮快
First, the classification of ash and its research Overview The form of ash produced by coal combustion and combustion of coal and combustion temperature are closely related. According to the formation of different conditions, the ash can be divided into three categories, the first is the liquid residue of pulverized coal or cyclone furnace formed by the coal granulated slag it generally experienced rapid rise above 1600 ℃ and water quenching Quench process, of which 70 to 80% or even 90% into the vitreous and quickly cooled down, but the use of liquid slag less than the number of pulverized coal wastes; the second is the solid waste slag formed by the pulverized coal stove Fly ash residue (fly ash accounts for about 85%, pulverized coal slag accounts for about 15%), it has experienced 1100 ~ 1500 ℃ high temperature rapid rise and air suspension fast
