Heat-resistant fuel-activating substance

Abstract

A fuel-activating substance comprising a fuel-activating material and having heat resistance imparted thereto. This fuel-activating substance can hence be applied or attached even to parts to be used under such temperature conditions that use with organic resin binders has been impossible, whereby the effect of saving energy in combustion devices is further heightened. The heat-resistant fuel-activating substance is characterized by being obtained by melt-mixing 50-150 wt. % metallic thermal spray material with 100 wt. % fuel-activating material of which the spectral emissivity for electromagnetic waves with wavelengths in the range of 3-20 μm is 0.85 or more and making the mixture capable of thermal spraying. Alternatively, 100 wt. % the fuel-activating material and 50-150 wt. % metallic material having a melting point of 420° C. or lower may be formed into a sheet through melting. Furthermore, a mixture of 100 wt. % the fuel-activating material and 75-150 wt. % inorganic resin having a heat resistance temperature exceeding 300° C. may be formed into a sheet or may be subjected to thermal spraying or applied in a molten state.
