As an important industrial pillar in China, the flue gas emissions generated by the production process of steel mills have always attracted much attention. In order to ensure that steel plants meet environmental standards, real-time monitoring of flue gas emissions is particularly important. In flue gas emission monitoring, the installation of a hygrometer is an indispensable part. This article will detail the locations and importance of hygrometers in the monitoring of flue gas emissions in steel mills.
HT-LH361 HT-LH366 capacitive hygrometer adopts the original imported humidity sensor, unique corrosion-resistant design, and can achieve long-term accurate measurement of gas humidity in a high humidity environment of 170 °C; It has the characteristics of high measurement accuracy, weak acid resistance, strong anti-interference ability, fast response speed and stable and reliable performance. It is widely used in the measurement of humidity in desulfurization equipment, ultra-low emission, VOC and other occasions in the flue gas continuous monitoring system CEMS, and can also be used for humidity control of wood, building materials, papermaking, chemical, pharmaceutical, tobacco, printing and dyeing, low-temperature economizer, bag dust removal, etc.

1. The entrance of the flue gas discharge pipeline.
When the flue gas is discharged from the blast furnace, converter and other equipment, its humidity is high. The hygrometer installed at the inlet of the flue gas exhaust pipe can monitor the humidity of the flue gas in real time and provide data support for subsequent dehumidification treatment. At the same time, by comparing the humidity data of different pipe inlets, the source of flue gas can be determined, providing an effective regulatory basis for the environmental protection department.
Second, after the flue gas dust removal equipment.
The flue gas of the steel plant contains a large amount of dust and harmful substances, which must be treated by dust removal equipment before it can be discharged. A hygrometer is installed after the dust removal equipment to monitor the humidity of the flue gas after the dust removal treatment. If the humidity is too high, it may mean that the dust removal equipment is running abnormally or the dust removal effect is not good, so it is necessary to adjust the equipment parameters or replace the filter bag and other accessories in time to ensure that the flue gas is discharged up to the standard.
3. The outlet of the flue gas emission pipeline.
A hygrometer is installed at the outlet of the flue gas exhaust pipe to monitor whether the flue gas after a series of treatments meets national and local standards. If the humidity exceeds the standard, the front-end treatment equipment needs to be inspected and optimized to ensure that the final flue gas discharge meets environmental requirements. In addition, the humidity data at the outlet can be used as a basis for the environmental protection department to charge the steel plant for discharge.
Fourth, the elevated source platform.
For some elevated source platforms, traditional humidity monitoring equipment is difficult to reach due to their high location. In this case, it is particularly important to install a hygrometer with wireless transmission function. Through wireless transmission technology, the humidity data on the overhead source platform can be transmitted to the monitoring center in real time, providing first-hand information for managers to ensure the normal operation of flue gas emissions.
In the monitoring of flue gas emissions in steel plants, the installation of hygrometers is of great significance to ensure that environmental protection standards are met. Real-time monitoring and control of flue gas humidity can be achieved by installing hygrometers at key points such as the inlet of the flue gas discharge pipeline, behind the dust removal equipment, at the outlet and on the elevated source platform. This will not only help steel mills improve environmental awareness and optimize production processes, but also provide a strong regulatory basis for environmental protection authorities. In the future, with the continuous progress of technology, it is believed that the application of hygrometer in the monitoring of flue gas emissions in steel plants will be more extensive and deeper.
