摘要：

利用热工理论与工程技术分析了蒸汽压缩技术应用于再沸器时其技术特点以及对再热器运行成本和节能减碳的影响。从运行可靠性、经济性和节能减碳效果3个方面全面分析了蒸汽压缩技术应用于再沸器的优点与缺点。分析结果表明，蒸汽压缩技术应用于再沸器的技术在运行可靠性、经济性和节能减碳上都为再沸器提供更有优势的热源。运行可靠性上，蒸汽压缩技术的应用使得再沸器运行温度更加恒定可控，降低再沸器物料积碳和局部热应力过大的问题与风险；经济性上，蒸汽压缩技术的应用使得再沸器运行成本相比电导热油锅炉降低62.9%；节能减碳效果上，蒸汽压缩技术的应用使得再沸器比使用电导热油锅炉的情况下减碳65%左右，为国家实现碳中和的长远目标提供有效的技术升级。因此，开发更高效更宽工作范围的蒸汽压缩技术和应用技术迫在眉睫。

Abstract:

Based on thermal theory and engineering technology, this paper analyzes and calculates the technical characteristics of steam compression technology applied to reboiler and its influence on reheater operation cost, energy saving and carbon reduction. The advantages and disadvantages of steam compression technology applied in reboiler are analyzed from three aspects of operation reliability, economy and energy saving and carbon reduction effect. The analysis results show that the steam compression technology applied to the reboiler can provide a more advantageous heat source for the reboiler in terms of operation reliability, economy, energy saving and carbon reduction. In terms of operation reliability, the application of steam compression technology makes the operating temperature of reboiler more constant and controllable, and reduces the problems and risks of carbon deposition and local thermal stress of reboiler materials; in terms of economy, the application of steam compression technology reduces the operating cost of reboiler by 62.9% compared with conductive hot oil boiler; in terms of energy saving and carbon reduction effect, the steam pressure of reboiler is higher than that of natural gas boiler. The application of carbon reduction technology makes the reboiler reduce carbon by around 65% compared with the case of using conductive hot oil boiler, which provides an effective technical upgrade for the country to achieve the long-term goal of carbon neutralization. Therefore, the development of more efficient and wider operating range steam compression technology and application technology is imminent.
