Gas turbines for expansion project at Chinese iron and steel complex

GE Energy’s turbine technology has been selected for the expansion of the on-site combined-cycle power plant at the Baoshan Iron & Steel Company (Baosteel) complex in Baoshan District, Shanghai, China.

Under a US$150 million contract, GE will supply a Frame 9E gas turbine, a SC5 steam turbine, a fuel gas compressor, generators and additional equipment for the project. GE previously provided similar equipment for the original power plant that was recently constructed at the site.

Shipments of the GE gas and steam turbines to the site are scheduled for September and November of 2009, respectively. Commercial startup of the plant expansion is scheduled for January 2010.

The project features the integration of iron technology using a COREX furnace instead of the traditional blast furnace. The COREX process burns uncoked coal, eliminating the need for a coking plant, one of the primary sources of iron or steel production emissions.

The gas produced by the COREX process will be used as the primary fuel for the 169 MW combined-cycle plant, which will provide electricity to the steel mill and to the local power grid. Backup fuel will be distillated oil.

The Baosteel facility is the largest iron and steel production complex in China and exports to more than 40 countries worldwide. The power plant expansion project is designed to increase steel and iron production and also help reduce Baosteel’s operational costs and site emissions.

‘Integrating GE’s gas turbine combined-cycle system into the COREX process improves energy conservation by approximately 10%’, said Jack Wen, GE Energy’s region executive for China.
