Problems solved by technology

In addition, some power generation companies in my country currently have chaotic management of turbine oil quality and a tendency to simply pursue the lowest purchase cost. They also urgently need to switch to a model that pursues quality, service life and rationalization of the entire process cost to provide protection for the long-term safety of the unit.

Abstract

The invention discloses steam turbine oil, which comprises 95 to 99.5 weight percent of base oil which contains less than 3 weight percent of sulfur and more than 90 weight percent of saturated hydrocarbon, 0.1 to 0.5 weight percent of amine antioxidant, 0.1 to 0.9 weight percent of sulfur-containing extreme pressure anti-wear additive, 0.02 to 0.1 weight percent of ashless anti-rust agent, and 0.01 to 0.05 weight percent of metal passivator. The steam turbine oil has the advantages of high quality, long service life and environment-friendliness.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a steam turbine oil used for a high-power gasoline unit. Background technique [0002] In recent years, with the rapid development of the national economy, my country's electric power industry has also developed rapidly. The new thermal power plants or the expansion of old thermal power plants are all developing in the direction of large capacity. Generally, the capacity of a single unit is at least greater than 300MW, and most of them are 600MW, and some even reach 1000MW. . With the increase of single unit capacity of steam turbine, the steam parameters (temperature, pressure) of steam turbine continue to increase, and the supercritical high-power steam turbine with good economy has become the main development direction of China's electric power industry. Therefore, high-quality turbine oil will predominate. At present, domestically produced units generally use domestic b...
