Description

单工质蒸汽联合循环Single working substance steam combined cycle 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，这使得采用单一热力循环理论实现制冷、供热或转化为动时能源利用率不理想。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. Under normal circumstances, the temperature of the heat source decreases with the release of heat, and the heat source is variable temperature; when fossil fuels are used as the source energy, the heat source has the dual characteristics of high temperature and variable temperature at the same time, which makes the use of a single thermal cycle theory to achieve cooling and supply The energy utilization rate is not ideal when the heat is converted into motion.
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。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 and steam is used as the circulating working fluid to achieve thermal variable work, it is affected by the temperature and pressure resistance of the material. And safety restrictions, no matter what parameters are used for operation, 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.
人们需要简单、主动、高效地利用燃料生成或其它的高温热能来实现制冷、供热或转化为动力，这需要热科学基础理论的支撑；在热科学基础理论体系中，热力循环是热能利用装置的理论基础和能源利用系统的核心；热力循环的创建及发展应用将对能源利用的飞跃起到重大作用，将积极推动社会进步和生产力发展。People need simple, active and efficient use of fuel generation or other high-temperature heat energy to achieve cooling, heating or conversion into power, which requires the support of the basic theory of thermal science; in the basic theoretical system of thermal science, the thermal cycle is a thermal energy utilization device The theoretical basis and the core of the energy utilization system; the creation, development and application of thermal cycles will play a major role in the leap of energy utilization, and will actively promote social progress and productivity development.
从简单、主动和高效地实现温差利用的原则出发，针对高温热源或变温热源的动力应用，力求为热动系统的简单化和高效化提供理论支撑，本发明提出了单工质蒸汽联合循环。Starting from the principle of simple, active and efficient utilization of temperature difference, aiming at the power application of high-temperature heat source or variable-temperature heat source, and striving to provide theoretical support for the simplification and high efficiency of the thermodynamic system, the present invention proposes a single working substance steam combination cycle.
