-)第二章项目提出的依据和必要性1.项目背景可行性研究报告随着我国人口的不断增加和经济的快速发展，资源相对不足的矛盾将日益突出，寻找新的资源或可再生资源，以及合理的综合利用现有的宝贵资源将是我国今后如何确保经济可持续发展的关键所在。为此，早在 1996 年国务院就制定并出台了一系列开展资源综合利用的政策，倡导要坚持资源开发与节约并举，并把节约放在首位，一切生产、建设、流通、消费等各个领域，都必须节约和合理利用现有的各种资源，千方百计减少资源的占用和消耗。开展资源综合利用，是我国的一项长期的重大技术经济政策，也是我国国民经济和社会发展中一项长远的战略方针，对于节约资源、改善环境状况、提高经济效益，实现资源的优化配置和可持续发展具有重要的意义。人类生存和社会发展进步所必须依赖的石油、煤炭、水等均属于资源的范畴，均属于全人类、全社会所必须予以保护和合理综合利用的资源领域。为贯彻落实国家资源综合利用的鼓励和扶持政策，加强资源综合利用管理，鼓励企业开展资源综合利用，促进经济社会可持续发展，国务院制定国家鼓励的资源综合利用认定管理办法，本办法自 2006 年 10 月 1 日起施行。原国家经贸委、国家税务总局发布的资源综合利用认定管理办法（国经贸资源1998716号）和资源综合利用电厂（机组）认定管理办法（国经贸资源2000660号）同时废止。管理办法中规定：申报资源综合利用认定的综合利用发电单位，还应具备以下条件：······按照国家审批或核准权限规定，经政府主管部门核准（审批）建设的电站······；以工业生产过程中产生的可利用的热能及压差发电的企业（分厂、车间），应根据产生余热、余压的品质和余热量或生产工艺耗气量和可利用的工质参数确定工业余热、余压电厂的装机容量。对审定合格的资源综合利用企业，主管部门颁发资源综合利用认定证书，资源综合利用认定证书是各级主管税务机关审批资源综合利用减免税的必要条件。利用水泥生产过程中的余热建设电站后，电站的产品电力将回用于水泥生产，这套系统在回收水泥生产过程中产生的大量余热的同时，又减少了水泥厂对环境的热污染以及粉尘污染，这将给企业带来巨大的经济效益。这套系统是一个典型的循环经济范例。2004 年 9 月 28 至 29 日，国家发展改革委在北京召开全国循环经济工作会议。会议作了题为“贯彻和落实科学发展观，大力推进循环经济发展”的报告。会议指出，循环经济是一种以资源的高效利用和循环利用为核心，以“减量化、可行性研究报告再利用、资源化”为原则，以低消耗、低排放、高效率为基本特征，符合可持续发展理念的经济增长模式，是对“大量生产、大量消费、大量废弃”的传统增长模式的根本变革。发展循环经济有利于形成节约资源、保护环境的生产方式和消费模式，有利于提高经济增长的质量和效益，有利于建设资源节约型社会，有利于促进人与自然的和谐，充分体现了以人为本，全面协调可持续发展观的本质要求，是实现全面建设小康社会宏伟目标的必然选择，也是关系中华民族长远发展的根本大计。 会议指出，要在五个环节加快推进循环经济发展。在资源开采环节，要大力提高资源综合开发和回收利用率；在资源消耗环节，要大力提高资源利用效率；在废弃物产生环节，要大力开展资源综合利用；在再生资源产生环节，要大力回收和循环利用各种废旧资源；在社会消费环节，要大力提倡绿色消费。2005 年 6 月，国家发改委和科技部在中国节能技术政策大纲2005 修订中明确指出：我国钢铁、化工、建材、石化、有色、轻纺、机械等主要耗能行业，目前工业窑炉余热利用率仅在 5%左右，到 2010 年，余热利用率应达到 15%左右。工业窑炉余能余热回收利用原则是“梯级利用，高质高用”。优先把高品位余能余热用于作功或发电，低温余热用于空调、采暖或生活用热。具体对于水泥行业的要求更加具体：要在大型新型干法水泥窑纯中低温余热发电。水泥生产线通过增设纯低温余热电站后，一般吨熟料成本可降低成本 1012 元左右。2005 年 12 月，国家发改委发布产业结构调整指导目录（2005 年本），其中就包括：日产 2,000 吨及以上熟料新型干法水泥生产余热发电。2006 年初，国家发改委等八部门发布的关于加快水泥工业结构调整的若干意见中，要求到 2010年，新型干法水泥采用余热发电的生产线达 40%。2006 年 7 月 26 日，国家发改委在北京召开了全国节能工作会议，各省、自治区、直辖市等主管节能工作的高官参加了会议。国家发展改革委指出，近年来随着经济规模的不断扩大，中国对能源的需求在持续较快增加，这已成为制约经济社会发展的瓶颈。缓解能源瓶颈制约的根本出路是坚持开发与节约并举，节能优先的方针，大力推进节能降耗，提高能源利用效率。为了强调当前节能工作的重要性，国家发改委在会议现场与三十个省、自治区、直辖市及新疆生产建设兵团和十四家中央企业负责人签订了节能目标责任书。中国财政部在会上表示，财政部要调整完善现有税收政策，择机出台有利于节能的优惠措施。包括：考虑将节能设备作为享受企业所得税优惠政策的对象之一，······鼓励节能设备推广使用；······鼓励环保和节能相结合······。中央财政将根据节能工作需要，着重从节能产品生产、节能设备应用、节能技术研发推广等方面入手，适时研究制定相应的税收优惠政策。这次会议预示着中国节能工作全面展- 3 -开。可行性研究报告由此可见，水泥行业建设已经迎来了建设纯低温余热发电的高峰期，这是社会和政府在能源节约和环境保护的巨大压力下提出的紧迫要求,也是水泥行业面对日益激烈的市场竞争的经济形势下的急迫要求。水泥窑余热电站建成后，可大力回收和循环利用水泥窑废气，提高水泥线的整体资源利用水平，为资源的绿色消费贡献力量。另外，利用水泥窑余热发电，实际上就是相应减少了电力系统中燃煤电站产生同等电量而产生的CO2的排放。根据京都议定书规定的基于市场经济原则的清洁发展机制（CDM），这些 CO2的减排量是可以在国际碳排放交易中出售的，从而可以减少余热发电的投资费用。能源是经济发展的重要物质基础，因此节约能源与开发新能源是我国经济发展建设中的一项主要任务。开展资源综合利用，是我国的一项长期的重大技术经济政策，也是我国国民经济和社会发展中一项长远的战略方针，对于节约资源、改善环境状况、提高经济效益，实现资源的优化配置和可持续发展具有重要的意义。水泥工业是耗能大户，在水泥生产成本中能耗约占生产成本的30%以上。针对水泥生产能耗高、成本高、效益低的局面，八十年代以来我国水泥企业在煅烧、粉磨、烘干、风机、余热利用、节电等方面做了大量的工作，取得了明显成效，但与先进国家的水平相比还存在很大差距，节能降耗是水泥工业当前和今后发展中必须解决的课题。水泥厂排出的废气有大量的余热资源，如何有效的利用这部分热源，许多科技工作者进行了长期的研究，提出了余热发电的设想。30年代起我国就有了中空回转窑的余热发电装备，至今已有十几套余热发电机组在运行。这些装备均为干法中空窑带余热锅炉的发电机组与窑外分解炉带补燃炉的中低温余热发电机组。由于多种原因，两者均未能得到广泛推广使用。随着水泥工业技术和装备水平的不断提高，窑外分解技术日益普及，而且废气温度较低，如何经济合理地利用这部分废气所含热力资源进行发电，已被国家列为重点科技开发项目。对于水泥厂的新型干法水泥生产线来说，余热发电量最大可达生产用电量的30%以上，大大地降低了生产成本，对促进水泥厂的发展壮大具有极其重大的现实意义，同时也将为水泥企业结构的调整和节能工作的发展起到积极的推动作用。2.水泥工业节能降耗水泥工业生产年耗电量为全国年
