Improvement of blast furnace straight pipe
The flue gas waste gas preheating system for the blast furnace gas utilizes the opportunity during the blast furnace maintenance to retrofit the existing heat pipe heat exchanger, which previously provided dual preheating for both gas and air. The original flue gas heat exchanger remains in place, while the existing air and gas heat exchangers are dismantled. A new gas heat exchanger is installed at the location of the previous gas heat exchanger, and the heat exchange tubes from the old systems are placed into a new tank. This approach makes full use of the existing supports, platforms, and external piping, reducing installation time and costs.
At the same time, an accountability system is implemented throughout the management process, playing a key role in enforcing strict controls within the state-owned enterprise. This ensures that every team member is responsible for their tasks, contributing to a more efficient and disciplined work environment. Ultimately, the company focuses on increasing production efficiency while reducing energy consumption. By promoting technological innovation, the company enhances its competitive edge and moves toward sustainable development, ensuring long-term stability and healthy growth.
A side-by-side adjustment system for maintaining an optimal air-fuel ratio is also introduced. During combustion, the amount of combustion air is adjusted based on the gas flow rate, ensuring that the ideal air-fuel ratio is maintained. This allows the furnace top temperature to reach the set point quickly and remain stable, helping to gradually increase the heat storage capacity of the regenerator. When the exhaust gas temperature reaches the required level, the hot blast stove is ready for switching. Exhaust gas analysis is used as a feedback mechanism to continuously adjust and correct the air-fuel ratio in real time, ensuring efficient and stable operation.
Additionally, improvements have been made to the blast furnace straight pipe. As wind temperature increases, the original air supply device's high-temperature resistance was insufficient, leading to red-hot and damaged straight pipes. To address this, the material of the straight pipe and the castable were upgraded, and some sections of the straight pipe and expansion joints were replaced. These changes have effectively resolved the issue. Through the transformation of the hot blast stove and various optimization measures, the wind temperature has steadily increased, and the main technical and economic indicators have significantly improved.
