As the nonequilibrium plasma micro discharges can generate a powerful energy flux, imparted to the flue gas, the molecules and atoms of pollutants are motivated and decomposed, and then NO X in the flue gas are decomposed and conversed in the particular conditions. Based on nonequilibrium plasma in combination with catalytic principle, an experimental investigation on NO X decomposition and conversion with Al 2O 3 catalysts was carried out and the NO X removal rate up to 95% was obtained. The NO X decomposition and conversion principle with Al 2O 3 catalysts was also discussed.展开更多

Based on boiler constricted air distribution, the experiment mainly tested the influence of primary air, excessive air, boiler load and milling sets (tertiary air) on NO x emissions and found its influence characteristics. A degraded bituminous coal is simply adopted to avoid the test results from other factors.展开更多
