通过分析目前纸机干燥部蒸汽冷凝水热力系统中常用的三段供汽和热泵供汽各自存在的问题,提出了一种新的方案——三段供汽和热泵供汽相结合,并且以一个五叠网涂布白纸板机实际生产工艺条件为例,详细地对系统中的蒸汽和冷凝水的热值进行了计算,以此说明新的蒸汽冷凝水热力系统方案在节能上的优越性。
By analyzing the problems existing in the three-stage steam supply and heat pump steam supply in the steam condensate water heating system of the drying section of a paper machine, a new scheme is proposed, namely, three-stage steam supply and heat pump supply and steam combination, An example of the actual production process of a five-stack wire coated white board machine calculates the calorific values of the steam and the condensed water in detail in order to illustrate the superiority of the new steam condensing water heating system in energy saving .
