摘　　要：与湿式排渣系统相比,干式排渣系统具有节水、节能、灰渣资源化等优点。干式排渣系统应用于不同容量锅炉时,会对机组热经济性产生不同程度的影响,如何提高锅炉热效率一直是学者们研究的重点。基于国内外现状,首先对干式排渣系统组成进行分析,随后给出锅炉热效率的计算方法,并重点分析干式排渣系统对锅炉热效率的影响。研究表明:该机组采用干式排渣系统后,锅炉热效率可提高0.09%左右。Compared with the wet sludge discharge system,dry slag system has the advantages of water saving,energy saving,ash utilization. Dry slag discharge system is applied to different boiler capacity,different degrees of influence on the thermal efficiency,how to improve the boiler thermal efficiency has been the focus of the scholars study. Based on the status quo at home and abroad,the first analysis of dry slag discharge system,then gives the calculation method of boiler thermal efficiency and dry sludge discharge system are emphatically analyzed the impact on the boiler thermal efficiency. Research shows that： the unit adopts the dry slag discharge system,the boiler thermal efficiency can increase 0.09%.
