摘要
针对提高传统化石能源的利用效率问题,结合朗肯动力循环与吸收式制冷循环,提出了一种利用朗肯循环对外做功发电,并通过吸收式制冷循环回收朗肯循环的冷凝热量及余热锅炉产生的低压蒸汽热量,以输出冷负荷的余热高效利用冷电联供系统,实现了系统余热的深度梯级利用。对该系统的热力性能进行分析结果表明,随着系统余热梯级利用程度的提高,综合能源利用率由52.4%提高到91.0%,相对节能率从33.2%提高到39.0%。
Aiming at enhancing the fossil energy utilization efficiency,a combined cooling and power （CCP） system for high efficient utilization of waste heat was proposed,combing with Rankine cycle and absorption chiller.This system does work to generate power through Rankine cycle,and recover condensate heat from the Rankine cycle and low pressure steam heat from a heat recovery steam generator （HRSG）by the ab-sorption chiller,thus to supply the cooling load and realize deep cascade utilization of the system waste heat.The thermodynamic performance of the CCP system was investigated.The results show that,with im-provement in waste heat cascade utilization degree of the system,the total energy utilization ratio increased from 52.4% to 91.0%,and the primary energy saving ratio （PESR）was increased from 33.2% to 39.0%.
