Abstract

Nowadays, NOx emission was taken more and more seriously, Emission standard of air pollutants for thermal power plants was enacted newly by Chinese State Environmental Protection Department which is considered to be the strictest NOx emission standard up to now, but similar to other NOx controlling regulations in the world, the present NOx emission metering form mostly base on concentration limit value without referring to power plant efficiency. Thus, this paper proposes a new NOx emission evaluation index as Power Generation Emission Rate and Power Supply Emission Rate for first time, then proceed to study NOx emission characteristic by two experimental parts, first part was carried out under unit different load via 6 experimental cases, second part was carried out under unit same load via the other 6 experimental cases. The results indicates that, whether under different unit load, or under same unit load, the new NOx emission index can evaluate boiler de-nitration technology more precisely in a quantitative way and owns a better applicability than traditional NOx concentration value, Power Supply Emission Rate of NOx can evaluate NOx emission characteristic more directly while unit supply per kilowatt-hour power to grid, which offers a new direction for objective evaluation to different kinds of de-nitration technologies.
