摘　　要：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。Based on the analysis of advantages and disadvantages of three-stage steam supply and heat pump steam supply, this article proposed a new kind program of thermal control system of steam and condensate system in drier sectionin of the coated white paperboard machine, with five fold wires forming end, a detailed thermodynamic energy balance calculation process was calculated as an example of the new steam condensate on the heating system in energy-saving advantages of the program to promote the program in practice and further applications.
