-I- 摘要 钢铁工业是国民经济的重要基础产业，是国之基石。但近20年的粗放式发展也 使企业遭遇产能过剩，能耗过高，排污过大的瓶颈。“十二五”期间，钢铁企业面临 去产能、创新发展乏力、环境能源约束不断增强等问题，企业持续经营面临困境。 在这种情况下，企业采用节能技术，引进节能减排项目，对于降低能耗、减少污染 物排放及企业的降本增效至关重要。 M钢铁公司为了降本增效引进副产煤气高温超高压发电项目，本文将对该项目 进行全面的技术经济评价，具体分析如下： 首先，从钢铁行业现状和评价理论实际出发阐述本文的选题背景以及研究意义， 同时根据查阅的文献资料总结了技术经济评价理论在国内外的发展沿革及研究现 状，进而又分析了本文的研究内容和研究方法。 其次，对相关理论和本文所使用的层次分析法及模糊评价法进行详细的介绍， 阐述了M钢铁公司副产煤气高温超高压发电项目建设的必要性、合理性，同时也针 对M钢铁公司高温超高压发电机组与目前国内和国外通用的发电机组方案进行对 比，对3种选型进行了具体的技术对比分析。 再次，在确定了M钢铁公司高温超高压发电机组建设方案为：1×265t/h高温超 高压煤气锅炉+1×80MW中间一次再热凝汽式汽轮机+1×85MW发电机组之后，建设 方案中所涉及的燃料供应、设备选型以及污染物排放等多方面内容进行了深入的技 术经济分析，从而为同类企业进行相关节能技术选型提供理论参考。 最后，根据技术比较、经济分析及综合评价的结果，确定了M钢铁公司高温超 高压发电机组建设的可行方案；从技术水平、经济效果和环境影响三个方面出发， 构建层次分析法和模糊评价方法的评价模型，通过模型对综合评价指标体系的一致 性检验，进一步论述了该发电机组建设方案的可行性。 关键词：煤气发电；节能；技术经济分析；综合评价 燕山大学工商管理硕士学位论文 -II- Abstract PerformanceTheironandsteelindustryisanimportantbasicindustryofthenational economyandacornerstoneofthecountry.However,theextensivedevelopmentinthep ast20yearshasbecomethebottleneckofenterprises'sufferingfromexcesscapacity,exce ssiveenergyconsumptionandexcessivedischargeofpollutants.DuringtheTwelfthFive-Y earPlanperiod,ironandsteelenterprisesarefacingproblemssuchaslossofproductionc apacity,lackofinnovationanddevelopment,andtheunceasingboostofenvironmentalen ergyconstraints.Enterprises'continuousoperationisfacingdifficulties.Inthiscase,itisv eryimportantforenterprisestoadoptenergy-savingtechnologyandintroduceenergy-savi ngandemissionreductionprojectstoreduceenergyconsumption,pollutantemissionsand cost-effectiveness.
