摘要： 以钢铁联合企业煤气不平衡理论为基础,分析了富余煤气波动、分配和放散的特点,基于统计学方法建立了煤气系统动态数学模型,并以某钢铁联合企业煤气系统为背景,开发了调试简单的煤气仿真系统.实例仿真计算结果表明:优化分配改进算法能够缓解富余煤气的波动影响;仿真模型能方便地分析几种方案的优劣;通过调整设备参数可以调试理想柜容;采用混合调度能减少煤气放散和管网报警;转炉煤气柜并网运行可提高回收率20%左右;焦炉改造后,煤气柜容量扩大一倍才能实现近零放散.

Abstract: Based on the gas imbalance theory in an iron and steel complex, the fluctuation, distribution, emission and buffer of gas surplus are analyzed to develop a dynamic mathematical model statistically. Then, with the gas system in a certain steel trust taken as example, an easy-to-debug dynamic gas simulation platform is developed, on which the simulation results show that an optimal distribution algorithm can alleviate the fluctuation of gas surplus and the simulation model will facilitate the comparative analysis of the merits and demerits of several gas recycling schemes, thus making the gas system available to realize the ideal gas tank capacity through readjusting plant parameters and debugging. By hybrid scheduling, both the emission of gas and frequency of pipeline alarm can be reduced. The converter gas tank in joined pipeline system can improve the gas recovery rate by about 20%. #1 and #2 coke ovens reformed, the near-zero emission will be achieved only if the relevant gas tank capacity is double.
