摘要:
燃煤火力发电技术是当前能源结构下最主要的发电技术,在未来50年内也将占据主导。煤炭等化石燃料资源仍是电力的主要来源,短期内不会被替代。当前火电装机总容量与其他发电技术相比也有绝对优势,占比约60%。火力发电的关键在于节能环保,随着技术革新,目前已发展为超超临界压力机组,功率可达1000 MW,发电效率达到50%左右,经济环保的同时提高了能源效率。然而,在极端的温度与压力下,材料的性能成为制约发电效率的关键因素之一。从燃煤火力电站选用材料的角度,介绍了耐热钢及耐热涂层的使用。渗铝是传统的化学热处理方法,是提高电站关键材料热稳定性的有效途径,综述了渗铝涂层的制备方法及新型技术。此外,煤炭超临界水气化制氢发电具有广阔的应用前景,对此技术及涂层在新型电站的使用进行了展望。
Abstract:
Coal-fired thermal power generation technology is the most important power generation technology at present. It will play a dominant role in the next 50 years. Coal and other fossil fuel resources are still the main source of electricity and will not be substituted for the short term. Compared with other power generation technologies, the total installed capacity of thermal power accounts for about 60%, which has absolute advantages. The key to thermal power generation is energy utilization and environmental protection. With the development of technological innovation, the new type of ultra-supercritical unit possess power up to 1000 MW and power generation efficiency up to 50%. It was not only economical and environmentally-friendly but also improved energy efficiency. However, under extreme temperature and pressure, the performance of materials has become one of the critical factors which restrict the efficiency of power generation. From the view of the material application for coal-fired thermal power plants, this paper introduced the use of materials such as heat-resistant steel and heat-resistant coating. Aluminizing is a traditional chemical heat treatment method, which can improve the thermal stability of materials in major parts of the power plant. In this paper, the preparation methods and new technologies of aluminized coatings were reviewed. Also, hydrogen generation by coal supercritical water gasification has broad prospects. The application of this technology and coating in new power plants has been prospected.
