摘要
在工业生产过程中,大量中低温余热直接排放大气,造成巨大的能源浪费和环境污染。卡林纳循环采用氨水混合物作为工质,具有气化温度低和非等温吸热的特点,因此,在简要介绍其工作原理的基础上将其应用于中低温余热回收,采用遗传算法对卡林纳循环和常规朗肯循环的主要参数进行了优化,在相同的余热条件下,比较了卡林纳循环和常规朗肯循环的净输出功率。结果表明,针对不同的余热类型,卡林纳循环和朗肯循环在余热回收利用方面各有优劣。
In the process of industry production, there are a great deal waste heats which are directly discharged into environment and result in serious energy waste and environment pollution. The Kalina cycle which uses ammonia-water mixture as the working-medium, has the characteristics of lower vaporization temperature and non-isothermal heat absorption. Therefore, the Kalina cycle is used in low temperature waste heat recovery based on introduction of operating principle. The primary parameters of Kalina and Rankine cycle are optimized by mean of genetic algorithm respectively, and the net output power of the two cycles is compared on the same condition. The result shows that both Kalina and Rankine cycle have respective advantages in the different waste heat types.
