Experimental Study on the Pollutants Release Characteristics During Combustion of Lean Coal with Different Coal Rank

Abstract:

In this paper, the characteristics of SO₂ and NO release during combustion of lean coal with different coal rank were experimentally studied in the one-dimensional furnace for pulverized coal combustion. The results showed: The coal property and proportion of the component coals have great influence on the characteristics of SO₂ and NO release. The releasing concentration of SO₂ and NO distributing along the furnace height is generally between that of component coals, and the releasing characteristics of SO₂ and NO would be more near to that of the larger proportion coal. The measuring value of the formation concentration of SO₂ and NO are different from the calculating value based on the weighted means of the component coals to a certain extent. While the different coal are added to lean coal, the time corresponding with peak value releasing concentration of SO₂ and NO is different.
