钢铁企业副产煤气产耗预测方法研究进展

Development of Forecasting of Generation and Consumption of Byproduct Gas in Steel Plants

钢铁企业的副产煤气系统复杂且工况多变,副产煤气产生量和消耗量瞬时波动,容易引起副产煤气调度分配不当,进而造成大量放散,而对副产煤气产生量和消耗量进行精确预测是解决此问题的重要前提。文章通过综述钢铁企业副产煤气预测研究的文献,发现目前对于副产煤气的预测方法可大致分为:基于系统机理的预测方法和基于历史数据的预测方法。但二者都存在自身的局限性,而采用两者组合的煤气预测方法可以对各自的缺陷进行互补,具有很广阔的研究和应用空间。

The complex and multivariate byproduct gas systems of steel plants are complex and multivariate,which is easy to cause an improper scheduling,due to the instantaneous fluctuation of the byproduct gas generation and consumption,and a resulted gas emission. Accurate prediction of byproduct gas generation and consumption is an important prerequisite for solving this problem. This study summarizes the literature on the prediction of byproduct gas in steel plants,and finds that the current forecasting methods for byproduct gas can be roughly divided into： forecasting method based on system mechanism and forecasting method based on historical data,but both of which have their own limitations. The combination of the two methods of gas prediction can be used to complement their respective defects,with a very broad research and application space.
