摘要： A burner using a high-temperature combustion catalyst is disclosed. The disclosed burner using a high-temperature combustion catalyst comprises: a mixing and dispensing unit for mixing and dispensing fuel gas and air, which are to be supplied; a combustion catalyst unit for generating heat by catalytically combusting with the fuel gas to be supplied from the mixing and dispensing unit; and a premixing chamber for preliminarily mixing a combustion gas which is to enter the combustion catalyst unit while connecting the mixing and dispensing unit and the combustion catalyst unit, wherein the combustion catalyst unit comprises: a front/rear-open housing having a chamber therein; perforated plates provided on the front and rear surfaces of the housing so as to allow the fuel gas to pass through from the rear of the housing to the front thereof; a pellet-type combustion catalyst filled inside of the chamber of the housing; and a heat source means for generating a heat source for the catalytic combustion of the combustion catalyst. The high-temperature combustion catalyst further comprises preparation by the steps of: preparing a metal precursor solution containing a transition metal nitrate, an alkaline earth metal nitrate, and aluminum nitrate; preparing a precipitation solution; preparing a mixture solution by mixing the metal precursor solution and the precipitation solution; increasing the temperature of the mixture solution to 90˜100° C. and maintaining the same for 10˜48 hours so as to cause precipitation; separating a precipitate slurry, which is formed by precipitation, from the mixture solution by filtering the same; washing the precipitate slurry; performing drying in order to remove water contained in the washed precipitate slurry; and performing firing at 1,000˜1,500° C. in order to remove water remaining in the dried precipitate slurry.
