Engineering thermodynamics is an important course in the course system of process equipment and control engineering. It mainly introduces the law of mutual conversion of thermal energy and mechanical energy based on the two laws of thermodynamics and the measures to improve the thermal efficiency when applied in the process industry. According to "three more and wide" characteristics of engineering thermodynamics course, the paper from the division of knowledge points, the emphasis on experimental teaching to the increase of engineering cases in the teaching reform, so as to arouse students' interest in learning and cultivation of practical talents with certain engineering literacy.
