The traditional and perfect blast furnace hot blast stove combustion automation system has perfect basic automation. The mathematical model is used to calculate the required heating gas flow and combustion air flow, and the basic automation is set. Complete basic automation for hot gas furnaces that burn mixed gas or burn preheated blast furnace gas and preheated air, including gas flow control, air flow control, air/fuel ratio control, vault temperature control and exhaust gas temperature control, as shown . In the early stage of the combustion of the hot blast stove, the large gas volume and the appropriate air-fuel ratio (preferably with the combustion exhaust gas component analysis device, the air-fuel ratio is corrected according to the residual oxygen amount) are rapidly heated to make the dome temperature quickly reach the specified value. Then, gradually increase the air volume to keep the dome temperature at the specified value. During the exhaust gas temperature management period, that is, when the temperature reaches a certain value, it is necessary to reduce the amount of gas and air to maintain the exhaust gas temperature at a set value. For the hot blast stove with three-eye burner for burning blast furnace gas and coke oven gas, since blast furnace gas and coke oven gas are separately fed, it is necessary to separately control the flow rate of blast furnace gas and coke oven gas, and it is necessary to carry out blast furnace gas and Coke oven gas flow ratio control, air-fuel ratio to meet the needs of blast furnace gas and coke oven gas, which makes the system loop more and more complex. The basic principle of the mathematical model of hot air furnace flow setting is to make the heat storage capacity of the hot blast stove bricks at the time of combustion meet the requirements of hot air temperature and flow rate. To meet this requirement, in addition to the complicated mathematical model, a gas composition analyzer is also required. This kind of instrument is not only expensive, but also requires good maintenance. To make the mathematical model effective, it also requires a sound foundation.
