Power plant upgrade |
The importance of CFD RJM harnesses its experience and expertise, alongside the power of CFD modelling, physical modelling and discrete element method modelling to help determine the optimal solution to resolve any combustion, emissions and performance challenges.
For the ZETES 2 unit 3 project, a series of CFD studies was undertaken to help build up an accurate picture of combustion behaviour at the plant (see opposite page).
Designing and building the new hardware
For the ZETES 2 unit 3 project, RJM did not need to fully replace the existing burners and burner assemblies but instead came up with an innovative and cost-effective upgrade solution that enabled some elements to be retained. In the image below, the new components designed and supplied by RJM are shown in green, while the grey components were retained. Also shown is the associated engineering drawing, exploded view.

standards. Additional wear resistance is assured through Stellite 6 hardfacing to high wear areas (shown in blue, below left) such as on the outer rim of the coal nozzles.
Installation
The entire upgrade project was completed during the 2024 spring/summer outage. The RJM team worked closely with the in-house team at ZETES and was supported by specialist external contractors.
Future prospects
Eren Group, as one of Turkey’s leading conglomerates, is committed to taking cutting- edge measures to improve the environmental record of each of its business lines and meet international standards. RJM is now working with Eren Enerji to develop upgrade solutions at other power stations within its generation fleet.
