Residual gas power generationThe company has utilized its own surplus gas to construct gas power generation, and has successively built 50MW high-temperature, ultra-high pressure, and the world's first 60MW ultra-high temperature, subcritical power generation unit. While meeting the national dual carbon policy, the company has also carried out energy conservation, cost reduction, and efficiency enhancement, increasing benefits for the enterprise and ensuring production。

Waste heat power generationSintering waste heat recovery is an important way to reduce energy consumption in the sintering process and improve energy utilization efficiency. The basic principle is that the sintered ore is cooled by blowing air on the ring cooler, and the cold air blown in from the bottom is heated when passing through the hot sintered ore layer, becoming high-temperature exhaust gas. In addition, a part of the sintering machine produces sintered ore by drawing high-temperature exhaust gas from the bottom to the flue, which is introduced into the boiler through the induced draft fan, heating the water in the boiler to produce steam. The steam drives the turbine to rotate and drive the generator to generate electricity。
Ecology Factory
Fully implement ultra-low emissions and strive to build a garden factory。
Entrusted with the professional design of Nanjing Forestry University, with an investment of 150 million yuan, to build a 427 acre Longteng Ecological Picking Garden, surrounded by orchards, forests, and green shade. It integrates the "Party Building Center", "Reception Center", and "Employee Activity Center", expanding the green area of the factory to 41.3%。
