本文分析了单热源动力装置中利用中、低温热源的热力循环,及其装置的要求和存在的问题后,提出:用多热源热力循环联合利用几种不同热源发电的理论和装置。作为例示,拟出太阳热,火力与地热或深水温差热相联合的热力循环和装置,并对它们和单热源的热力循环进行热力计算,将结果列表示知,以判断多热源发电厂在技术经济上的优越性。 This paper analyzes the thermodynamic cycle of using medium and low temperature heat sources in a single heat source power plant, the requirements and existing problems of the devices, and puts forward the theory and device of utilizing multiple heat sources to jointly utilize several different heat sources to generate electricity. As an example, a thermodynamic cycle and device that combines solar heat, firepower with geothermal or deep-water temperature and temperature heat is developed and thermodynamic calculations are performed on the thermodynamic cycles between them and a single heat source. The results are tabulated to determine whether a multi- Economic superiority.
