Abstract:
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.

Abstract:
Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.
