Zest Energy secures Mondi steam turbine contract

October 2012 News

Zest Energy has secured the contract to supply a new steam turbine to international paper and packaging group Mondi’s Richards Bay mill. This project will see the supply of the largest turbine ever manufactured by Brazilian company TGM Turbinas (model CTE63). Not only will the project be the first of its kind to use the combination of a TGM turbine and an alternator manufactured by Electric Machinery, it will also be a first for both equipment manufacturers to have their equipment installed in South Africa. The contract is also the first time since WEG acquired EM, that TGM and EM equipment has been used in combination worldwide.

“Currently there are two AEG Kanis steam turbo generators installed, one 38 MW extraction back pressure steam turbine and one 34 MW extraction condensing steam turbine,” explains Zest Energy projects manager, Alastair Gerrard. “We are now installing a new 48 MW multi-extraction condensing steam turbine to use the additional high pressure steam provided when running the plant boilers at full load.

In addition to the 48 MW steam turbine and the 57 MVA, 11 kV EM alternator, the scope of equipment includes the complete condensing system, lubrication oil system with piping, turbine control panel and HMI, generator protection and control panel and a spare parts set to guarantee 98% equipment availability over the next five years. Zest Energy will provide OEM supervision services during installation and commissioning and will offer 24/7 on-call support for a period of four weeks after handover. A separate long term service agreement is being discussed.
