hp磨煤机磨制经济性煤种的运行特性
, PP. 56-60
Keywords: hp磨煤机,运行特性,分离器,转速,煤粉细度
Abstract:
研究了hp1163/syn型磨煤机在磨制神混煤和印尼煤时的运行特性。结果表明:煤粉细度r90随动态分离器转速升高而降低;动态分离器转速在600~750r/min时,单位转速变化引起的煤粉细度变化是该转速范围的2~3倍;随着动态分离器转速的增加,磨煤单耗升高,且转速越高,单位转速变化引起的磨煤单耗增加幅度越大;随着进口一次风量增加,出口煤粉含水率先升后降。建议c磨煤机磨制神混煤分离器转速为778r/min,e磨煤机磨制印尼煤分离器转速为617r/min。
