摘要: Abstract The purpose of the present study is to clarify effects temperature, initial SO 2 concentration and steam addition on 3 formation under oxy-fuel combustion. experiments consisted two parts. first part was homogeneous experiment conducted with simulated flue gas in a horizontal tube furnace. In order further characteristics heterogeneous atmosphere, other carried out by using high-sulfur coal low-sulfur respectively drop results indicated that increased but then decreased temperature increasing, maximum appeared at around 950 °C. increase could significantly enhance formation. But injected inhibited all test cases obviously, as injection kinds radical pool compositions gas, which might involve more complex interactions formed during wet recycling. Moreover, compared former experiment, latter presented intense inhibiting behavior, probably attributed diversification pulverized-coal
