摘要：煤粉流量调节阀在国内气流床粉煤气化装置中广泛使用,对于调节控制煤粉流量发挥着重要作用.在中国石化安庆分公司的Shell煤气化装置上,对进口煤粉流量调节阀进行性能测试和研究.结果表明,该煤粉流量调节阀在其开度低于20%时,阀门开度变化对流量的调节最为敏感,开度大于40%后,几乎没有调节流量的作用.分别给出了在煤粉循环系统和气化炉运行系统中该调节阀的压降特性及其压降占系统总压降的分率值,并对提升阀门性能及优化操作提出了建议.
Mass flowrate regulating valve of coal powder has been widely used in entrained-flow pulverized coal gasification plants and plays an important role in the regulation of coal mass flowrate.The performance of the imported regulating valve in Anqing Shell Coal Gasification Plant was tested.The test results showed that the pulverized coal flowrate was significantly sensitive to the valve opening while it was below about 20％.When the valve opening was more than 40％,the valve became almost ineffective in regulation.Meanwhile,its pressure drop characteristics in both conveying loop process and gasifier feeding process of pulverized coal were also analyzed.Based on the performance studied,the optimization for the gasifier feeding operation was suggested.
