METHOD FOR FORMING ANTI-CORROSION AND ANTI-OXIDATION COATING LAYER ON HIGH-TEMPERATURE COMPONENTS OF GAS TURBINE FUEL ADDITIVE

摘要

In a method for effectively depositing an anti-corrosion and anti-oxidation material, such as silicon dioxide, on high-temperature components of a gas turbine, including blades rotating at a high speed during the operation of the gas turbine, an organic compound including a metal ingredient, such as silicon, is added to a fuel for the gas turbine, such as LNG, diesel or kerosene, or the organic compound is sprayed into combustion air so that the organic compound can burn together with the fuel, in order to improve the durability of the high-temperature components. Silicon dioxide, produced by burning a silicon organic compound together with the fuel, is uniformly deposited on all the high-temperature components of the gas turbine, which are exposed to the combustion gas of a high temperature, thus forming an anti-corrosion and anti-oxidation coating layer of a thickness of several to several tens of μm on the high-temperature components during the operation of the gas turbine.
