Abstract: This paper delves into the integration of high-efficiency and energy-saving fans in the dust removal system of steel industry, highlighting their pivotal role in enhancing production efficiency and minimizing energy usage and emissions. It provides an in-depth analysis of the fans' structural features and performance benefits, including their broad high-efficiency operating range, wear-resistant materials, and refined airflow channel design. Utilizing the case study of Chongqing Iron and Steel Co., Ltd, the paper illustrates the substantial increase in fan efficiency and the notable decrease in energy consumption post-upgrade. The paper concludes with an optimistic view of the future for high-efficiency fans in industrial energy conservation, underscoring their impact on corporate sustainability and green transformation initiatives.
