Engine & Turbine Technology
Within the scope of this project, Alstom replaced the high-pressure steam turbine in unit 8 with a high performance new module and upgraded the medium and low-pressure cylinders, the generator and the balance of plant – thus enabling the turbo group and its auxiliaries to operate in a highly efficient combined cycle mode.
Joint venture For its part, Siemens has announced that it is teaming up with the Russian company Power Machines OJSC within the next few months to set up a gas turbine joint venture, in which Siemens will hold a 65 per cent stake and Power Machines the remaining shares.
Te joint venture headquartered in St Petersburg is intended to perform engineering, manufacturing and servicing of gas turbines in Russia and the other countries within the Commonwealth of Independent States (CIS). Te new company is scheduled to start operations as soon as the official permits have been issued. “Te new joint venture will enable us to better serve
the growing market for gas turbines, and gas power plants and combined cycle power plants in the CIS,” said Michael Suess, ceo of the Siemens energy sector. “We’re investing in Russia to build up production capacity for leading-edge power plant technology. We want to make our contribution toward modernising the power industry in the region, and our target is to strengthen our position as market leader. For us it is extremely important to be active in Russia as a local player,” Suess added.
Industrial gas turbines In a separate development, Siemens Energy has received an order for the supply of three industrial gas turbines to Tanzania. Siemens’ customer is the Norwegian company Jacobsen Elektro, which will build a power plant for the state-owned energy provider Tanzania Electric Supply Company Limited (TANESCO). Te three SGT-800 gas turbines will be supplied to
the Ubungo power plant located in Dar Es Salaam, the largest city in Tanzania. For the Ubungo power plant, Siemens will supply
three SGT-800 industrial gas turbines with a combined capacity of 100MW. Connection to the grid is planned for late 2011. Te natural gas for the power plant is supplied through a pipeline from the Songo Songo gas field off the coast of Tanzania. “With our gas turbines we can support the
development of a reliable power supply in Tanzania,” said Markus Tacke, ceo of the industrial power business unit of Siemens Energy. In Tanzania, fewer than than 10 per cent of the population of 40 million has access to the national power grid. Te country depends mainly on hydro power, with only a few gas-fired power stations in place. ●
The original Roots* blower still leads the way
With the 2011 acquisition of Dresser, GE’s air and gas movement offerings now include Roots blowers, compressors and controls. These positive displacement blowers and centrifugal compressors are employed worldwide in a variety of applications including: petrochemical; flue gas desulfurization; power generation; effluent treatment and metal refining.
Roots blowers, compressors and controls deliver air and gas flows from 3 m3 430,000 m3
/hr. to /hr. So you can expect
innovative solutions from us wherever air and gas moves anywhere in the world.
