Alstom’s Combined Cycle Power Plant to be Fed by ThyssenKrupp Blast Furnace Gases
06/13/2007 - Alstom has received a turnkey contract from Brazilian steel producer ThyssenKrupp CSA Companhia Siderúrgica to build a 490-MW turnkey combined cycle power plant that will be fuelled by blast furnace waste gas from ThyssenKrupp’s new steel mill.
Alstom has received turnkey contract from Brazilian steel producer ThyssenKrupp CSA Companhia Siderúrgica to build a 490-MW turnkey combined cycle power plant. The project is valued at 330 million euro.
The power plant, to be located in Sepetiba, Rio de Janeiro State, Brazil, will be fuelled by blast furnace waste gas from ThyssenKrupp’s new steel mill, which will be built in parallel. 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 from an early stage. 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 erection. The power plant will integrate in-house core plant components including two GT11N2 gas turbines, heat recovery steam generators, one steam turbine, and three turbo generators.
Alstom’s GT11N2 gas turbines have the unique ability to burn waste gases with low calorific value, as those produced at the Sepetiba steel plant. The turbines produce, when integrated in an Alstom combined cycle, 10 % more power compared with the more conventional steam plant solutions typical for blast furnace gas applications.
“Using gas that would otherwise be wasted to produce power is both of economic and environmental benefit,” said Philippe Joubert, President of Alstom Power Systems. “Alstom has a range of power solutions which can help industry reduce emissions and maximize commercial value.”
