TheadvantageofCFBboilerfedwithlimestone在循环流化床锅炉运行中，石灰石作为辅助燃料对锅炉的良好运行，烟气排放起着至关重要的作用。DuringtheoperationofCFBboiler,itisveryimportanttouselimestoneasauxiliarymaterialforemissionmonitoring.首先，加入石灰石可以降低SO2和NOX的排放，满足环保要求。Firstofall,limestonecouldreducetheemissionofSO2andNOXandsatisfytheenvironmentrequirement.第二,加入合适的粒度的石灰石可以改善床料的粒度分布，从而提高床料质量，提高炉膛内换热效率。Secondly,feedwithrightgrainsizelimestonecouldimprovethespreadofbedmaterial,inordertorisethebedmaterialqualityandincreasetheheatefficiencyinsidetheboiler.第三，加入合适的粒度的石灰石会增加旋风分离器入口的烟气密度，从而提高旋风分离器的分离效率，增加参与大循环床料量，提高锅炉热效率，脱硫率。Thirdly,feedwithrightgrainsizelimestonecouldincreasethesmokedensityofcycloneseparatorinlet,whichmakeshigherseparatingefficiencyandincreaseslargecirculatingfluidizedbedmaterialquantityandboilerheatefficiencyandrateofdesulfurization.第四，加入石灰石后，CaCO3与煤中的硫反应生成CaSO3后，CaSO3和CaO与床料混合，同时CaSO3附着在床料颗粒的表面，这样一来就减低了床料的硬度，这将减低对炉膛内的水冷壁管的磨损和冷渣器的磨损。Fourth,afterfeedingwithlimestone,CaCO3reactswithsulfurinthecoalandmakesCaSO3,CaSO3andCaOmixwithbedmaterial,atsametime,CaSO3attachedonthebedmaterialsurface,soitreducesthehardnessofbedmaterial,itwillreducethewearonwaterscreentubeandslagcoolerinsidetheboiler.总之，石灰石粉的加入对锅炉的正常运行起着至关重要的作用。Allinall,limestonefeedingisveryimportantforboilernormaloperation.二：系统图
