Abstract

Abstract

The theoretical combustion temperature in front of the tuyere is one of the important parameters for evaluating the thermal state of the blast furnace hearth. On the basis of the traditional theoretical combustion temperature calculation model, the influence of ash content, unburned coal powder, and SiO₂ gasification rate on the theoretical combustion temperature was comprehensively considered, and the theoretical combustion temperature calculation model was revised. The research results indicate that, the influence of factors ignored by traditional calculation models on the theoretical combustion temperature ranges from 53 to 55 ℃. The influence of oxygen enrichment rate, coal injection rate, blowing humidity, air temperature, coal fuel rate, coal preheating temperature, ash content, and SiO₂ gasification rate on the theoretical combustion temperature decreases in sequence. The suitable theoretical combustion temperature control range for the blast furnace at Panzhihua Steel & Vanadium Co., Ltd. is 2160~2320 ℃. And under the condition of constant blowing humidity, the suitable control range for the theoretical combustion temperature is 2220~2 280 ℃. After applying real-time online calculation of theoretical combustion temperature to the regulation of blast furnace production operations, it effectively promotes
- blast furnace,
- theoretical combustion temperature,
- calculation model,
