针对超超临界一次再热机组、汽轮发电机组抽汽回热过热度高,造成回热系统不可逆损失大、系统完善度不佳等问题,分析了MAST CYCLE热力系统(简称MC系统)热力学性能,此系统可有效降低回热抽汽过热度,但系统相对复杂。采用热力学参数优化、匹配及结构集成方法对超超临界一次再热机组进行分析优化,得到加4级外冷器优化系统为系统集成的最优方案,供电效率达到49.58%;并对其进行余热利用挖潜,计算得到系统供电效率达到50.07%。研究结果为700℃超超临界机组系统优化设计提供了一种更有效的途径。
The superheat degree of steam extraction is high in the ultra-supercritical single reheat unit. It results in largely irreversible loss and poor system perfection. The thermodynamic performance of the MAST CYCLE thermodynamic system was analyzed
which can effectively reduce the superheat of regenerative extraction steam. However
the system is relatively complex. The optimization system of single reheat with 4-stage external coolers is the best scheme of system integration
and the power supply efficiency reaches 49.58%. The waste heat of the system was used. The calculation results show that the power supply efficiency of the system reaches 50.07%
which provides a more effective way for the optimization design of 700℃ ultra-supercritical unit system.
