Siemens Energy Service Fossil in Newcastle has won a new multi-million pound order for the supply and installation of three intermediate pressure (IP) steam turbine modules with Drax Power Limited, owner of Europe's largest coal-fired power station. The new modules will contribute to Drax's efficiency improvement program.
The new contract was awarded following the hugely successful completion of the £100 million turbine upgrade project which, over a period of five years, saw the replacement of the high pressure and low pressure turbine modules of all six generating units at Drax Power Station. The turbine modernization project has increased the overall efficiency of the power station to almost 40 percent and reduced its carbon dioxide emissions by one million tons a year. Drax's turbines are now among the most efficient in the world.
Commenting on the new order, Peter Emery, production director at Drax said, "We have taken the decision to upgrade the intermediate pressure turbines of the three generating units that are to be converted to burn sustainable biomass in place of coal. This will optimize the efficiency of those units by helping to offset any loss in efficiency experienced as a result of the change in fuel diet. The project builds on the success of the major turbine upgrade program completed last year and underlines our commitment to delivering leading operational performance in power generation."
The new design means that the intermediate pressure (IP) turbine will be installed as a module, which will support the ease of installation and reduce the required outage duration.
This new project will be delivered by joint teams from Siemens in the UK and Germany. Siemens steam turbine engineering team in Newcastle is undertaking the design and draughting elements of the project. The IP modules will be manufactured at Siemens' factory in Mülheim an der Ruhr with critical support from Newcastle's engineering, projects and field service teams. The turbines will be installed at Drax by an integrated team of Drax and Siemens engineers, technicians and craftsmen.
Each IP module weighs 63.5 tons and has 26 rows of blades. The first module is scheduled to be installed in 2014 with project completion expected in 2015.
