Gas for power generation technologies for steel companies can help China's steel industry achieve its dual-carbon targets and cope with the EU's Carbon Border Adjust-ment Mechanism(CBAM)trade barriers.By studying the development of gas boiler power generation technology in iron and steel enterprises and its impact on carbon emission,iron and steel enterprises with an annual production capacity of 10 million tons of crude steel can reduce annual carbon dioxide emission by adopting the new high-efficiency ultra-supercritical parameter gas boiler power generation technology to reduce annual carbon diox-ide emission by 1.8857 million tons,which is an increase of 15.71%compared with that by adopting the high temperature and ultra-high-pressure gas power generation technology.Through the calculation and analysis based on the rules of the EU's CBAM,the steel ex-port cost per unit of steel enterprises adopting the new ultra-supercritical parameter gas boiler power generation technology is lower than the overall level of China's iron and steel industry by about 94.2 yuan per ton,with a relative reduction of 10.9%.
