摘　　要：无论是对新装机组或对老机组进行改造，要成功地应用炉内喷钙脱硫技术还存在许多问题。本文通过实验研究，分析了煤粉炉内喷钙后对结渣、沾污、灰负荷和灰浓度、比电阻、磨损等产生的影响。认真分析喷钙后产生的新问题，对新电厂的设计或者电厂的改造具有现实意义。Whether to application in a new unit or to improvement of an old one, there arelots of problems in applying limestone desulphurization technology in pulverized-coalboilers successfully. Through experimental study, this paper gives an analysis to the effectson slagging, fouling, ash load, ash concentration, specific resistivity, wear etc. afterlimestone desulphurization, which is practical in designing a new power plant or improvingan old one.
