Abstract
A method of preventing high temperature corrosion on a heat exchanging surface of a biomass boiler, including: a first feeding step, supplying a first biomass fuel to the boiler; a deposition step, performing combustion on the first biomass fuel during initial operation of the boiler, and forming an inert deposition layer on a surface of a heat exchanger of the boiler; a second feeding step, supplying a second biomass fuel different from the first biomass fuel to the boiler; and a normal combustion step, performing combustion on the second biomass fuel. A direct contact of an alkali metal chloride with a metal pipe wall is prevented by forming an inert deposition layer on the surface of the heat exchanger of the boiler in the deposition step, thereby establishing a physical barrier between the heat exchanging surface and the alkali metal chloride to prevent corrosion on the metal pipe wall.
