Combining the acid dew point formula and computational fluid dynamic(CFD)method

this paper proposed a new method to predict the sulfuric acid deposition behavior on the heat exchanger surfaces.The deposition theory and reliability of the numerical model was further confirmed by experimental results from a small-scale test bench.The results show that

the deposition theory this paper proposed agrees well with the actual situation

this numerical model is accurate and reliable.The sulfuric acid deposition on the heat exchanger surface usually shows dynamical deposition.The increase in temperature gradient and flue gas velocity could make the deposition be violent.The high SO3 concentration in the flue gas could result in a higher dew point and severer deposition.
