Abstract

Simulating atmospheric condition in superheater's region of biomass boilers

a study on corrosion test of tube material 20G commonly used on boilers has been carried out.By using basic principles in chemical kinetics and thermal analysis

the test data have been processed

obtaining the conclusion that the corrosion of tube material 20G in gas-phase HCl adheres of the two-dimentional diffussion mode.The activation energy and pre-exponential factor in the reaction have been calculated

obtaining the kinetic expression of said corrosion.The process and mechanism of chlorination corrosin have been also analysed.
