This product adopts the first set of ultra large, ultra clean, and full process new technologies independently developed by China Heavy Industry Institute. It has the world's largest specification of Φ 13.5m cylindrical electrostatic precipitator and an ultra large flue gas energy efficient recovery gas cooler. The purified flue gas dust emission concentration index reaches the highest standard, and its safety guarantee system reaches the highest level.

The successful production of this project is a major breakthrough in our institute's dry flue gas dust removal technology for large tonnage converters, and another successful demonstration and promotion of major environmental protection technology equipment encouraged by the country. The key technological equipment developed has high efficiency, low energy consumption, stable and reliable performance, intelligent and remote monitoring capabilities, providing valuable experience for achieving high-quality production processes for domestic and foreign ultra large converters. The successful application of this product has a significant demonstration role in achieving negative energy steelmaking in China's steel industry and achieving zero emissions and low-carbon development of green steel. The promotion and application of this product has saved users the cost of steelmaking, achieved good economic benefits, and also created huge environmental benefits for society.
