摘要：According to the fuel properties of biomass (straw), it analysis the element content of the Cl, S in biomass straw and alkali meta such as K, Na and the composition of biomass (straw) and ash, meanwhile it analysis the composition of fly ash deposits sediments on heating surface of straw fuel boiler and determines the components of depositional aggressive medium and its mass ratio. A simulation corrosion test is designed base on the mass ratio and other conditions; it obtains the corrosion morphology and corrosion products by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). Finally it determines the process of alkali metal chloride deposition corrosion is mainly self catalytic oxidation corrosion.
