【摘要】 本文从我国能源资源的构成特点出发,从能源结构和利用技术层面综合分析了我国当前能源供应中能源利用效率偏低的原因。探讨了煤炭高效清洁利用的途径,其中包括先进的煤发电技术、供暖技术和煤气化技术。重点从安全性,经济性,环保效益等方面对煤气化合成二甲醚作城镇燃气的能源供应方案做了深入研究,提出了城镇燃气供应新方案。此外,还对建筑节能技术进行了探究,着重介绍了中小城镇中太阳能和生物质等可再生能源的开发和利用。从宏观和技术层面对我国城镇化进程中能源的供应方式提出了合理建议。更多还原

【Abstract】 This thesis, based on the characteristics of energy mix, comprehensively analyze the reason why energy efficiencies is relatively low in current energy supply from two aspects----energy structure and utilization technology. The thesis discusses the high efficient and clean utilization technologies, including advanced coal-power generation technology, heating technology and coal gasification technology. It does deep research of DME made by gasification as the urban gas supply, mainly from the angles of security, economical efficiency and environment protection, and present new program of urban gas supply. Besides, the thesis does research on building energy efficiency, mainly present the development and utilization of renewable energy sources, such as solar energy and biomass energy in medium-small towns, put up reasonable proposals of energy supply in urbanization from macroscopic view and technical level.更多还原
