Steam turbine manufacturer Doosan Škoda Power has entered into a contract to supply a one-core DST-S20 steam turbine with complete accessories for a waste-to-energy plant in Olsztyn, Poland.

The new plant, scheduled to be completed in 2023, will be capable of processing up to 110,000 tons of refuse-derived fuel (RDF) produced by the citizens of the greater Olsztyn area.

According to Doosan Škoda, the plant will cover about 30% of the district heating demand in the city by replacing old coal-fired sources of heat. This will ensure a secure supply of district heating to the local citizens while offering a sustainable alternative to fossil fuels. In addition, the thermal treatment of the waste makes it possible to reduce the landfill space required and will reduce CO2 in the Olsztyn area.

In this PPP project, Doosan Škoda will work together with other members of the Doosan consortium – the EPC partner, along with Doosan Heavy Industries & Construction, and Doosan Lentjes, as the technology provider. The end customer of the incinerator is Dobra Energia dla Olsztyna.

“The assembly is unique in that it has a radial outlet with extraction points, while similar types of turbines had an axial outlet in the past. The assembly’s total power will be roughly 12MW,” says Tomáš Winkler, project manager at Doosan Škoda Power.

Dobra Energia Dla Olsztyna is a Polish project designed to manage combustible municipal waste through thermal conversion with energy recovery. The project was funded through the European Union to the value of 172 million PLN ($47 million). The construction of the waste incineration plant together with the peak load boiler house in Olsztyn was carried out on the basis of a public-private partnership agreement, MPEC being the public partner and Dobra Energia dla Olsztyna being the private partner.
