鞍钢高炉喷煤流量调控技术研究

Development of pulverized coal flow rate regulating and controlling technique for BF at Anshan Iron & Steel Co.

介绍了鞍钢高炉喷吹煤粉流量调节控制技术的研究过程、装置构成、工作原理及工业试验的结果。高炉喷吹煤粉总体流量调节控制系统由传感器、大口径电容噪声式流量变送器、大能力可调量给煤器及STD总线工业计算机所组成。试验结果表明,该项技术是实现稳定均匀喷吹的重要措施。

This paper introduces the development,equipment composition,working principle and industrial experiment result of the pulverized coal flow rate regulating and controlling technique for BF at Anshan Iron & Steel Co.The total injection flow regulating and controlling system consist of sensor,large diameter capacitance-noise type flow transducer,large ability weight adjustable coal feeder and STD bus industrial control computer.The experiment result indicates that this technique is a important measure to realize stable and even pulverized coai injection.
