Alstom wins blast furnace contract

Alstom has received a €330m turnkey contract from Brazilian steel producer ThyssenKrupp CSA Companhia Siderúrgica to build a 490MW turnkey combined cycle power plant.

The power plant, to be located in Sepetiba, Rio de Janeiro State, Brazil, will be fuelled by blast furnace waste gas from a new steel mill, which will be built in parallel by the customer, with excess energy exported to the national grid.

The project will be carried out in two phases, with the plant operating in simple cycle first, allowing power to be produced early on in the project. In the second phase, further equipment will be added to give full combined cycle operation.

Alstom will provide all engineering, procurement and construction services to deliver a fully integrated blast-furnace-gas-fired combined cycle plant including balance of plant, civil works and construction. The power plant will integrate in-house core plant components consisting of two GT11N2 gas turbines, heat recovery steam generators, one steam turbine and three turbo generators.

Alstom’s GT11N2 gas turbines are designed to burn waste gases with a low calorific value, like those produced at the Sepetiba steel plant.
