摘要
为核对气化炉水汽系统的水动力安全或优化气化炉水汽系统的操作,提出了通用水动力计算模型,开发了适用于干煤粉气化系统的水动力计算软件。以神华宁煤烯烃GSP干煤粉气化的水动力系统为算列,模拟结果表明,排渣口处水路出口温度软件计算值为168.8℃,运行监测值为168.3℃,其他水路出口温度计算值与监测值最高偏差<2.2%;排渣口水路进出口温差的计算值比运行监测值低1.3℃,而烧嘴支撑和水冷盘管计算值与运行监测值的偏差<0.3℃;循环水罐、汽包和泵相关参数的模拟值与工业实际运行数值完全一致。
In order to check the hydrodynamic security of stream-water system or optimize stream-water system operation of gasifier, general hydrodynamic calculation model is put forward and hydrodynamic calculation software suitable for dry pulverized coal gasification system is developed. The results show that the software calculated value and monitoring value of water outlet temperature of slag discharge are 168.8℃ and 168.3℃, respectively. Maximum deviation of calculated value and monitoring value is less than 2. 2% for other water outlet temperature. The calculated temperature difference of slag discharge between Inlet and outlet is 1.3℃ lower than that of monitoring value. Deviation value of calculated and operational monitoring is less than 0. 3℃ for burner support and water cooling. The simulation values of eireulating water tank, steam drum and pump related parameters are completely accorded with the industrial practical value.
