Description

联合循环动力装置Combined cycle power plant 技术领域：Technical field:
本发明属于能源与动力技术领域。The invention belongs to the field of energy and power technology.
背景技术：Background technique:
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。Cold demand, heat demand and power demand are common in human life and production; among them, the conversion of heat energy into mechanical energy is an important way to obtain and provide power. In general, the temperature of the heat source decreases with the release of heat, and the heat source changes temperature. When fossil fuels are used as the source of energy, the heat source has the dual characteristics of high temperature and variable temperature, which makes it difficult for power plants based on a single thermal cycle to convert more heat energy into mechanical energy; for high-quality fuels, traditional ones can be used. The gas-steam combined cycle achieves high thermal efficiency, but there are still problems such as high cost, large investment, and thermal efficiency to be improved.
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。Take the external combustion steam power plant as an example, the heat source is high temperature and variable temperature heat source; when the Rankine cycle is used as the theoretical basis, water vapor is used as the circulating working fluid to achieve thermal variable work, due to the temperature and pressure resistance of the material And safety restrictions, no matter what parameters are used, there is a large temperature difference between the circulating working fluid and the heat source, and the irreversible loss is large, resulting in low thermal efficiency, which also means that the potential for improving thermal efficiency is great.
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。People need simple, active, safe and efficient use of thermal energy to obtain power. For this reason, the present invention proposes a combined cycle steam power device that has high thermal efficiency, strong safety, adapts to high-temperature heat sources or variable-temperature heat sources, and can handle various fuels. .
