Analysis and Simulation of Oxidation Causes During Steam Turbine Oil Use Based on Fenton Oxidation

Abstract

Steam turbine oil mainly plays the role of lubrication, heat dissipation and speed regulation in the steam turbine unit. The viscous deposits generated during the operation of steam turbine oil can affect the heat dissipation and lubrication of the equipment. In the long-term oxidation process, due to the influence of oxygen, heat, water, impurities and other factors, degradation products will be produced. The characteristic of Fenton oxidation method is that it has super strong oxidizing ability and can be deeply oxidized and degraded. The Fenton oxidation method is mainly based on the reaction time and temperature and the pH value between the adsorbent and the adsorption phase. In order to adjust the additive formulation and prevent the turbine oil from turning green during use, it needs to be evaluated by appropriate experimental methods. The purpose of this article is to use the Fenton oxidation method to analyze the causes of oxidation during steam turbine oil use. Through the analysis of pH value-color change by Fenton oxidation method, the structure and source of the coloring matter are inferred. In this paper, three steam turbine oils are selected for physical and chemical performance and failure analysis. The experimental results show that the use of Fenton’s reagent can accelerate the color and chemical structure of the oxidation products during the oxidation process similar to the color-forming substances in the used steam turbine oil.
