Electrical Power
Companhia Siderúrgica de Tubarão is a self-producer of electrical power, and our surplus generation is sold to third parties with the authorization of ANEEL, the National Electrical Power Agency.
The gases resulting from the production processes of Blast Furnaces 1 and 2 (BFG - Blast Furnace Gas), from the Coke Oven (COG - Coke Oven Gas) and the Steelmaking Plant (LDG - LD Gas - currently under implementation) are utilized in power generation by the 04 thermo-power plants at ArcelorMittal Tubarão.
These gases are sent to the consumers and gasometers responsible for guaranteeing the pressure of the distribution network. Part of these gases (approx. 50%) is consumed by the thermo-power plants, where both electrical and mechanical power are produced. The mechanical power provides the blast flow for the blast furnaces. This power keeps the blast furnace burden suspended.
Another source of Electrical Power is the TRT (Top Recovery Turbine). Differently from what occurs at the thermo-power plants, the gas is not burned. The TRT is a turbine that receives the gas from the Blast Furnace and makes it lose pressure. This pressure drop is able to generate Electrical Power through the expansion of gases.
The great importance of producing Electrical Power lies in the recycling of gases resulting from the steelmaking process. The environmental gain is indisputable, since it avoids the exploration of energy sources such as hydropower and thermopower, which are consumers of fuels withdrawn from nature. This also allows for the sustainable development of ArcelorMittal Tubarão, without increasing the exploration of the aforementioned energy sources. In addition, ArcelorMittal Tubarão commercializes its surplus generation, thus becoming a supplier of Electrical Power for the national power grid.
