Description

联合循环动力装置 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；其中，利用热能转换为机械能是获得和提供动力的重要方式。一般情况下，热源的温度随着热的释放而降低，热源是变温的。在以化石燃料为源头能源时，热源同时具有高温和变温的双重特点，这使得基于单一热力循环的动力装置难以将更多的热能转化为机械能；对其中的优质燃料来说，可以采用传统的燃气-蒸汽联合循环得到高的热效率，但仍然存在造价高、投资大、热效率有待提升等问题。
以外燃式蒸汽动力装置为例，其热源属于高温且为变温热源；当以朗肯循环为理论基础，采用水蒸气为循环工质实现热变功时，由于受到材料耐温耐压性能和安全性方面的限制，无论采用何种参数运行，循环工质与热源之间都存在较大的温差损失，不可逆损失大，导致热效率较低，这也意味着提高热效率的潜力甚大。
人们需要简单、主动、安全、高效地利用热能来获得动力，为此，本发明提出了热效率高、安全性强、适应高温热源或变温热源和能够应对各种燃料的联合循环蒸汽动力装置。
