在工业生产中,对热能的需求是很大的,以水蒸汽作为传热介质极为普遍。对自身设置锅炉房独立供汽的工厂而言,热能利用率是指所耗燃料在理论上所能产生的热量中,有百分之几是用于产品生产工艺所必需的。显然,这些工厂的热能利用率决定于热力系统中各个设备的热效率,包括锅炉热效率、供热管道的热效率、用热设备的热效率,以及余热的回收利用程度。但是,这些设备之间是相互影响的,而且一般不会同处于最佳效率之下。这里,就有系统匹配问题,以求得最高的总热能利用率。我们的目标,是以最
In industrial production, the demand for thermal energy is large, and it is extremely common to use water vapor as a heat transfer medium. For factories that set up their own steam supply in the boiler house, thermal energy utilization means that theoretically the amount of heat the fuel consumed can produce, and a few percent is necessary for the production process of the product. Obviously, the thermal efficiency of these plants depends on the thermal efficiency of each device in the thermal system, including the thermal efficiency of the boiler, the thermal efficiency of the heating pipeline, the thermal efficiency of the thermal equipment, and the degree of recycling of waste heat. However, these devices are mutually influential, and are generally not at the same optimal efficiency. Here, there is a system matching problem in order to obtain the highest total thermal energy utilization. Our goal is to
