摘　　要：阐述了某加热设备所需氮气执行气体的气源选型、压力自动控制及尾气排放控制,通过其实施可对液氮的使用、气动比例阀的应用以及高温废气的排放处理有了认识,对类似工程具有参考意义。This paper systematically describes how to select source gas type, automatic control its pressure and waste gas emission. We have a deep understand in usage of liquid nitrogen, application of pneumatic proportional valve and the treatment of high temperature waste gas after execution of this project. The knowlage will have a well reference in other similar application.
