Abstract In order to study the quantitative emission indexes of air pollutants emission of sinter flue gas（SFG），the existing problems and the development trend of the emission standard of air pollutants for SFG of the standard is analyzed. Then two kinds of calculation methods for calculating air pollutants emission of the SFG are proposed. One is the calculation method of the reference oxygen concentration， and the other is the calculation method of the sinter ore per ton. The two methods are about emission concentrations and emission intensities of air pollutants emission of the SFG. At the same time， on the basis of the second method， a method for calculating the limited production plan is proposed， which can be used to calculate the proportion of the production reduction accurately for each sintering machine in the limited region during the special period without using the one-size-fits-all approach. The application of this method will help enterprises to improve their own clean production level. Enterprises with high levels of clean production will be fewer limited in production， while those with low levels of clean production will be more limited in production.
