在等效热降理论的基础上 ,推导出热量以绝对量的形式进、出热力系统的数学描述———纯热量法。它是以机组的新蒸汽能级为基准 ,将机组其它各处的能量进行折算 ,得到系数 ξj———纯热量品位系数。根据 ξj 的大小不仅可以判定热力系统各处的能级高低 ,对于机组母管制补水系统 ,利用 ξj 的大小来判别补水由哪些台机组进入 ,再送至哪些台机组 ,以减少热力系统的不可逆损失 ,使热力系统处于最优运行状态。为电厂节能改造提供分析方法
On the basis of the equivalent thermal drop theory, it is deduced that the caloric input and output of the caloric system in the form of absolute quantity is the pure caloric method. It is the unit of the new steam level as a benchmark, the rest of the unit energy conversion, the coefficient ξ j --- pure calorimeter coefficient. According to the size of ξj not only can determine the level of energy system throughout the heating system for the crew of the parent system make up the water system, the size of the ξj to determine the replenishment by which units to enter, and then sent to which units to reduce the irreversible loss of heat systems, So that the thermal system in optimal operation.
