Abstract: The present invention provides a method for removing a deposit on a furnace wall of a blast furnace and a method for operating a blast furnace. In the method for removing a deposit on a furnace wall of a blast furnace, the upper surface of the material loaded into the blast furnace is lowered to the lower part of the deposit to expose the deposit, and water is sprayed onto the exposed deposit to remove the deposit. In this method, it is preferable to intermittently spray water by providing an interval between each spraying of water, and to remove the deposit while adjusting water spraying time, interval time, water spraying flow rate and total water spraying amount per spray so as to maintain a predetermined furnace heat level. The method for operating a blast furnace comprises a deposit removal step in which, during operation or when idle, the material loaded into the furnace is reduced to the lower part of the deposit and the deposit on the furnace wall is removed by the aforementioned method for removing a deposit on a furnace wall of a blast furnace.
