Description

分级蒸发联合循环蒸汽动力装置 技术领域:
本发明属于能源与动力技术领域。
背景技术:
冷需求、热需求和动力需求,为人类生活与生产当中所常见。在动力需求技术领域,利用热能转换为机械能是获得和提供动力的重要方式。对于诸如以核反应为驱动能源或热源具有很高温度的情况,以及采用水蒸气为循环工质的外燃式蒸汽动力装置而言,在蒸汽实现热变功时,由于受到材料耐温耐压性能和安全性方面的限制,循环工质与热源之间往往存在很大的没有利用起来的温差,即不可逆损失大,热效率低,这也意味着提高热效率的潜力甚大。
以采用水蒸气为循环工质的外燃式蒸汽动力装置为例,其在工作介质、低温放热环节和动力负荷范围等方面具有显著的优势——比如,水蒸气具有很宽的参数工作范围,循环的放热温度可接近环境,装置的负荷范围宽等;为了提高热能转换为机械能的效率,现行主要措施是使水蒸汽工作在临界、超临界或超超临界状态,这需要换热管束既承受高压又必须承受高温——这是极为困难的,导致蒸汽与燃气之间的温差仍然甚大。正是受制于材料性能,水蒸气的平均吸热温度与热源(如高温燃气)平均放热温度之间仍然存在很大温差,使得热效率的提升难以取得实质性突破;另外,采取临界、超临界或超超临界参数运行,还带来了蒸汽动力装置运行安全性的降低。
针对蒸汽动力装置的优点和在热效率及安全性方面存在的重大缺陷,针对其它将高温热能转换为机械能的情况,本发明提出了分级蒸发联合循环蒸汽动力装置;本发明能够在保留蒸汽动力装置优点的同时,大幅度提高蒸汽动力装置的热效率和装置运行的安全性。

本发明技术可以实现的效果——本发明所提出的分级蒸发联合循环蒸汽动力装置,具有如下效果和优势(主要结合以水蒸气为循环工质的蒸汽动力装置加以说明):
(1)保留传统蒸汽动力循环原有的优势。例如,在水蒸气为热变功介质的蒸汽动力循环装置中,水蒸气可作为循环工作介质,来源广泛,价格低廉;工作参数范围宽广,仍可选择工作在亚临界、临界、超临界或超超临界状态;与环境之间无任何非相容性,热污染极小等。
(2)与以水蒸气为循环工质的蒸汽动力装置相比较,相变过程中热源负荷(外部热源和膨胀机排放循环介质放热提供)大幅度增大,有利于减小温差损失。
(3)采用双循环流程,能够根据具体情况选择合适的工作介质。
(4)分级蒸发,实现温差合理利用,减少传热不可逆损失,提高热效率。
(5)高温区循环介质与热源介质同为气体,循环工质自热源吸热环节有利于降低温差传热损失,提高热效率。
(6)在高温区实现低压高温运行方式,解决传统蒸汽动力装置中热效率、循环介质参数与管材耐压耐温性能之间难以调和的矛盾,能够大幅度降低热源与循环介质之间的温差损失,大幅度提高热效率。
(7)在实现高热效率前提下,可选择低压运行,装置安全性大幅度提高。
