火电厂凝汽设备抽真空系统的教学设计——以榆林职业技术学院《电厂系统图绘制》实训课程教学为例

Teaching Design of Vacuum System for Condensing Equipment in Thermal Power Plant——Taking the Practical Training Course of Power Plant System Drawing in Yulin Vocational and Technical College as an Example

《电厂系统图绘制》实训课程是电厂运行人员必须掌握的一门课程,实训课时为60学时。该课程是学习《电厂仿真实训》和《热力发电厂》的基础。凝汽设备抽真空系统是该实训课程中的一个重要系统,是汽轮机主再热蒸汽系统的一个后续系统。以该系统为例,进一步理解凝汽设备抽真空操作对电厂正常运行具有非常重要的意义,此系统的学习能更好地为该课程教学提供思路和借鉴价值。

The practical training course of power plant system drawing is a course that the power plant operators must master.It is understood that at present,only Yulin Vocational and Technical College offers this course,with 60 class hours of practical training.This course is the basis of studying“power plant simulation training”and“thermal power plant”.The vacuum system of condensing equipment is an important system in the training course,and it is a follow-up system of main reheat steam system of steam turbine.Taking the system as an example,it is of great significance to further understand the vacuum system of condensing equipment for the normal operation of power plant,which can better provide ideas and reference value for the teaching of this course.
