轴向排气型煤气透平的轴承温度稳定控制方法及应用

A bearing temperature stability control method and application of axial exhaust coal gas turbine machine

简要分析了径向进气、轴向排气型煤气透平膨胀机的排气侧轴承温度增高的原因,如何避免煤气透平膨胀机排气侧支撑轴承温度的升高,对保证TRT机组的正常运行非常重要。通过该文提出的控制透平排气侧轴承温度升高的方法,使TRT机组自动化系统的控制功能更加完善。

This paper concisely analyses the reasons for bearing temperature rise of the exhaust side which happened to radial intake and axial exhaust gas turbo-expanders.How to avoid the exhaust side＇s bearing temperature rise of the gas turbo-expanders is very important to guarantee the normal operation of turbine unit.This paper put forward through the control of the turbine exhaust temperature method of lateral bearing,making the process control function of TRT unit＇s automation system further improving.
