摘要:
在双碳目标背景下,开展钢铁工业生产能耗预测研究对于钢铁工业降低生产能耗和提升效益具有重要作用。为科学预测钢铁工业生产能耗,基于2010—2022年钢铁能耗数据,通过建立DNGM(1,1)、IDGM(1,1)和DDGM(1,1)3种改进的灰色预测模型,对吨钢综合能耗和吨钢可比能耗进行数据预测和误差对比分析,选出最优模型,得到2023—2025年吨钢综合能耗和吨钢可比能耗预测结果。研究表明:灰色预测模型在钢铁能耗预测中具有可行性和适应性;DNGM(1,1)模型在钢铁工业生产能耗预测中整体模拟性能最优;2023—2025年吨钢综合能耗和吨钢可比能耗将持续下降。基于研究结果,建议我国钢铁行业进一步优化生产工艺和技术,改善能源结构,并加大对节能减排技术研发的投资,以达到节能降耗的效果,促进节能减碳目标的早日实现。
