摘要
为解决工业锅炉房存在的余热、废热资源浪费与自身用热、用电需求之间的矛盾,本文以某热水燃煤锅炉房为研究对象,提出了一种工业锅炉房ORC热电联供系统。通过分析工业锅炉房工艺特点与生产需求,构建回热型ORC热电联供系统数学模型,并采用粒子群优化算法对系统进行优化设计。结果表明单位净发电量所需换热器造价的最优值为984.3元/kW,系统废热热源利用率为45.74%,系统动态投资回收期为2.87年。该系统可在梯级利用余热、废热资源的同时,实现工业锅炉房用电的自给自足。
In order to solve the contradiction between the heat waste in the industrial boiler room and its own heat and electricity demand,this paper takes a hot water boiler room as the research object and proposes an ORC cogeneration system.By analyzing the characteristics and production requirements of the industrial boiler room,the mathematical model of the ORC cogeneration system is constructed.The particle swarm optimization algorithm is used to optimize the system operating parameters.The results show that the optimal value of heat exchanger costed per unit net power generation is 984.3 RMB/kW,the utilization rate of system waste heat source is 45.74%,and the system dynamic investment recovery period is 2.87 years.The system can realize the self-sufficiency of power supply in the industrial boiler room while utilizing waste heat in the cascade.
