What is the working principle of furnace static pressure?

Judging the changes of pressure and airflow in vertical and horizontal sections of blast furnace, reducing the large fluctuation of furnace conditions and avoiding abnormal furnace conditions are all related to gas flow from the perspective of fluid mechanics. The static pressure and pressure difference of the furnace body are also related to the gas flow. Therefore, the static pressure difference can be used to evaluate the possibility of blast furnace flooding and fluidization. Generally, with the increase of blast furnace air volume, the volume of gas in the furnace belly increases, the gas flow rate increases, and the lower pressure difference and the upper pressure difference will increase. The static pressure measurement system developed by Wuhan Huamin Measurement and Control Technology Co., Ltd. can provide detailed data.
