吉林工业职业技术学院毕业论文 论文题目：煤制燃气工艺设计 姓名：罗丽丽 指导教师：宋艳玲 专业：应用化工技术 系别：应用化工技术系 日期 摘要 中国是一个能源大国，但又是一个人均能源资源占有量的贫国，一次能源结构中75%以上是煤。预计到本世纪中叶，甚至到本世纪末，中国以煤为住主的能源结构将不会改变。煤的高效、清洁利用，是中国经济和社会可持续发展的战略选择。是保证中国能源稳定可靠供应以及可持续发展的重要科技基础。这也充分表明了中国发展洁净煤技术的重要性和紧迫性 为了满足未来经济、社会和环境协调发展对能源的需求，煤炭的洁净利用的新型工业化道路，发展基于煤气化的煤基能源及化工系统是在可预见范围内最有效的技术途径，已成为能源领域科技界和企业界的共识 大型煤气化技术是煤气化联合循环发电及多联产系统的核心技术。研究院经过近十年的努力，开发出了具有自主知识产权的两段式干煤粉加压气流床气化技术，并进行了实验研究，结果表明两段式干煤粉加压气化工艺具有冷煤气效率高、比氧耗小、自耗功大幅度降低、煤气冷却器 及净化系统的设备尺寸小、造价降低等优点。在完成中试实验的基础上，目前该技术已经进入工业化发展阶段，主要应用于清洁煤发电和煤化工领域。与目前国内外已经工程化的几种煤气化技术相比较，两段式干煤粉加压气化技术在工程造价、系统经济性能等方面都有比较明显的优势。 关键词：气化炉 干煤粉气化 工业应用 Abstract ???China is a big energy countries, but is a per capita share of energy resources of poor countries, a more than 75% of energy mix is ??coal. Is expected by mid-century, even to the end of this century, the Chinese live in the Lord with coal as the energy structure will not change. Efficiency of coal and clean use of Chinas economic and social sustainable development strategy selection. China is to ensure stable and reliable supply of energy and sustainable development of important scientific and technological base. This fully demonstrates that Chinas development of clean coal technology, the importance and urgency In order to meet future economic, social and environmental development of the demand for energy, clean coal use new road to industrialization, the development of coal gasification-based coal-based energy and chemical systems in the foreseeable range of the most effective technical means, has become an energy areas of consensus in the scientific community and the business community Large-scale coal gasification technology is coal gasification combined cycle power generation system and multi-core technology. Xian Thermal Power Research Institute after nearly a decade of effort, developed with independent intellectual property rights of the two-stage dry pressurized entrained flow coal gasification technology, and experimental results
