Abstract：The reburn denitration characteristics of coal co-with poplar was studied in a multi-function denitration test bed under the typical reburn denitration conditions. The research results indicate that coal co-with poplar can enhance the coal reburn denitration efficiency, the denitration efficiency of bituminous coal and lignite co-with poplar are 35 and 14 percentage points higher than that of the bituminous coal and the lignite at the rebum fuel fraction 20%, respectively. The optimal ratio of coal and poplar of the mixed fuels is 1: 1. The mixed fuels attain their highest denitration efficiency at the stoiehiometric ratio (S_R) 0. 6. With the temperature increasing, the mixed fuels reburn denitration effectiveness firstly decreases and then increases. The best suitable reburn fuel ratio and the resident time of the mixed fuels are 20% and 0.81 second, respectively. Under the typical operating conditions with reburn fuel ratio of 20%, NO removal efficiency of 58%～74% is achieved by coal co-with poplar reburning.
