Abstract

Abstract

With the increasing effort of national environmental governance of China, the ultra-low emission requirements of coal-fired power plants, steel mills and cement plants are also increasingly strict. Accurate monitoring of various pollutants in ultra-low emission flue gas is particularly important for the operation of pollution control equipment and environmental management. Therefore, in order to meet the need for accurate analysis of flue gas in the iron and steel industry, this paper introduced the principle and application of a high-temperature infrared flue gas detector, 9100HIR. And the comparative test of the instrument and some typical flue gas analyzers in a steel enterprise were conducted. The trend changes of the monitoring results had good correspondence with the online monitoring result, and the absolute error was within the acceptable error range. The comparison results of various analysis methods showed that the 9100HIR analyzer had good accuracy and field application ability, and could meet the detection requirements.
