毕业设计（论文）-水泥窑余热锅炉设计精选.doc

摘 要 目前，我国水泥工业中存在大量的中低温余热资源，这部分余热资源的热量占水泥生产工艺系统总热量的三分之一左右，若直接将其排放会造成能源的严重浪费。应用水泥窑低温余热发电技术将这部分余热资源回收加以利用，产生蒸汽进入汽轮机做功发电，可以大大地提高水泥企业的能源利用率。 本文主要阐述水泥窑余热发电的发展历程和发展现状，介绍水泥窑余热发电技术所存在的一些问题，同时对水泥窑纯低温余热发电技术的工艺流程和发展现状做一些阐述。最后根据国家的一些政策对水泥窑余热发电技术的发展前景作了一些展望。 首先，本次设计是设计一个32t/h 水泥窑余热锅炉的设计。然后，按方案设计时的选型进行热力计算、结构计算和校核，为各个部分选取正确的参数并确定结构形式。最后，根据计算结果和CAD绘制水泥窑余热锅炉总图。 关键词 : 水泥窑；发展历程；余热发电；余热锅炉；设计 Abstract At present, our country has large amounts of low temperature waste heat resources in cement industry, the heat of this part of the waste heat resources are around a third of cement production system. If they are emission-ed directly, it will cause serious energy waste. Take advantage of this part of waste heat resources by recovering low temperature waste heat power generation technology of cement kiln, and produce steam to power generation, which will increase energy efficiency of the cement enterprises greatly. This article focuses on the development of the cement kiln waste heat power generation process and the development status of, cement kiln waste heat power generation technology introduced by a number of problems, meanwhile, cement kiln waste heat power generation technology, process, yet, cement kiln waste heat power generation process technology and development of some elaborate. Finally, according to some of the policies of the national cement kiln waste heat power generation technology for the development prospects of some prospects. First, this design is to design a 32t/h cement kiln waste heat boiler design.Then, press the program selection for thermal design calculations, structural calculations and check, for each part of the selected parameters and to determine the correct structure.Finally, according to the calculations and CAD drawing cement kiln waste heat boiler assembly diagram.
