Doosan Škoda Power is working on the coal fired Palu 3 plant with its parent company Doosan Heavy Industries, which will supply two circulating fluidised bed boilers. The plant is being built for Indonesian government-owned power company, PT Perusahaan Listrik Negara (Persero).

Although rated at 50 MW, the steam turbine design includes “a reserve by which the power output can be raised to 64.5 MW”, says Markéta Leitlová, project manager, Doosan Škoda Power.

Doosan Škoda Power is working with its parent company Doosan Heavy Industries & Construction on the project.

Other recent steam turbine project developments reported by Doosan Škoda Power include the following:

  • Successful operation of two 204MW turbines at the 1509 MW Fadhili combined cycle power plant in Saudia Arabia, jointly owned by Saudi Aramco, Saudi Electricity Company and Engie. The two twin-cylinder DST-S10 turbines with no reheat have been operating since March 2020 at the Fadhili plant, located near the Jubail industrial city on the Persian Gulf.

This is Doosan Škoda Power’s first installation in Saudi Arabia, while elsewhere in the Middle East, Doosan Škoda Power turbines can be found, for example, in Zarqa, Jordan (185 MW), and Salalah II, Oman (2 x 89 MW).

  • Significant progress, despit eCOVID-19, on the Rookery South Energy Recovery Facility project, an energy-from-waste plant in the UK, for which Doosan Škoda Power is supplying and installing a 67 MW turbine set, on a turnkey basis, with a scope that includes generator, excitation transformer, oil system and high-pressure hydraulic system. Assembly is scheduled for completion by October 2020, with first steam to be generated in March 2021.

Main contractor for the plant is Hitachi Zosen Inova, while the developer is Covanta, in partnership with Veolia and the Green Investment Group.

“We are already implementing similar projects for Hitachi Zosen Inova in Istanbul and most recently in Newhurst in the UK”’ said Tomáš Starý, Doosan Škoda Power project manager.

Despite complications caused by COVID-19, the Rookery South turbine was manufactured andshippedtwomonthsaheadofthe deadline specified in the contract, says Doosan Škoda Power. At the beginning of May, ČEZ Distribution engineers assisted with the transport of the turbine, which weighed more than 240 tons, to the Port of Lovosice by lifting the power lines along the route.

  • Performance testing and handover of the steam turbine for ASV6 at the Asnæs CHP plant, Kalundborg, Denmark, which Doosan Škoda describes as “a unique double casing steam turbine with flexible coupling of the low- pressure turbine.”

The project is part of a project that will see Asnæs, which provides district heating to the local network and process steam to a nearby pharmaceutical plant, as well as power to the grid, converted from coal firing to biomass, mainly wood chips.
