Polish power plants choose Vorecon

World Coal,

The Vorecon variable speed planetary gear is to be utilised in the two new coal-fired power plants in Poland, Opole and Jaworzno III. Voith will present a model of the Vorecon to visitors to Stand 1O12 of Power-Gen Europe in Amsterdam from 9 - 11 June 2015.

Poland will invest approximately €25 billion in the expansion and modernisation of its power generation sector by 2024. Poland’s new power plants will rely on coal, in addition to gas. Jaworzno III will achieve gross installed electric power of 910 MW. In Opole, two new units of 900 MW each will help cover the future base load. Both power plants are designed with supercritical steam parameters and are among the most efficient power plants in Europe.

Type RW Vorecon variable speed planetary gears with power of 13 and 18 MW will control the speed of the boiler feed pumps in both systems. The Vorecon from Voith combines speed control system, gearbox and oil supply into one unit.

As base load power plants, reliable operation is a decisive factor for the units in Jaworzno III and Opole. The wear-free control of the Vorecon utilising hydrodynamic power transmission with a mechanical system of robust design renders trouble-prone power electronics unnecessary and triples the life cycle of the control component in comparison with electronic solutions.

In contrast to traditional drivelines with steam turbines, the boiler feed pumps of both new Polish power plants are driven by electric motors.
