电站锅炉脱硫方法的技术经济分析

Technical economic analysis of different desulphurization techniques for power plant boilers

叙述了电站锅炉各类脱硫方法的脱硫原理、技术特点、适用范围及运行成本核算等。目前，关于脱硫方法成本核算方面的文章较多，但相互之间缺乏可比性，究其原因，主要是由于计算时所包括的项目不尽相同所致。以中国计算运行成本(包括材料消耗、动力消耗、维修与管理、人工、折旧、大修、偿还投资贷款等)的规定为计算基础，将中国正在运行的或即将投产的较大的脱硫工程进行了运行成本的计算与相互比较。除了比较运行成本外，还进行了技术、经济综合指标的分析，以及选择脱硫方法时的注意事项。

In recent years, rapid development in energy and power industry has led to significant increase in sulphur dioxide emission for lack of appropriate techniques of desulphurization for coal-fired power plants and industrial boilers. It is therefore necessary to promote the research, development and application of these techniques.In this work, related were the operating cost account, principles of desulphurization, technical features, and scope of application of different desulphurization techniques for power plant boilers. Based on the stipulations for the operating cost account in China (inclusive of consumption of materials and power, maintenance and management, manpower, depreciation of equipment, overhaul charge, and investment loan repayment, etc.), operating cost calculations were carried out for the major desulphurization projects in China, which have been in operation or will be put into operation in the near future. The calculation results were compared. In addition, an analysis of the technical economic indices of different desulphurization techniques was made, and points for attention in selecting the technique were discussed.
