The objective of this study is to investigate partial oxidation of NO with desulfurization in dry sorbent injection(DSI) process using dry sorbent and additives. The effect of the main operating variables directly related to desulfurization efficiency has been also tested. These variables are Ca/S ratio, temperature, inlet SO2 concentration and gas flow rate. The experiment was carried out for partial oxidation of NO with desulfurization in dry sorbent injection process using NaClO2 and CaCl2. The experimental results showed that partial oxidation of NO with desulfurization was increased in DSI process using little NaClO2. It was also found that the injection of CaCl2 was effective in increasing only SO2 removal efficiency. Increase of SO2 removal performance and promotion of partial oxidation of NO using the two additives at low temperature was confirmed.
