Improving performance and reducing emissions at ZETES 2 unit 3, Turkey
Poor combustion and less than optimum boiler efficiency were among the problems being encountered at an Eren Enerji 615 MW supercritical power plant at Zonguldak on the Black Sea. Following extensive analysis and CFD modelling, the solution saw extensive modification of the entire burner and combustion system, while retaining as many “non-performance critical” components as possible, to reduce costs

Turkey is committed to achieving net zero greenhouse gas emissions by 2053 and has already made significant progress in its ongoing energy transition, placing a strong emphasis on renewable energy and energy efficiency. As part of this transition, coal-fired power plant owner/operators in Turkey are adopting the latest technologies to increase efficiency and significantly reduce their emissions of CO2
.
One such owner/operator is Eren Enerji, which is committed to improving its environmental record. Eren Enerji is a major supplier of electricity in Turkey, with 2790 MW of coal fired units, supplying almost 7% of the country’s
total electricity demand. Eren Enerji is part of Eren Holding, a Turkish conglomerate with investments in paper, packaging, retail, textiles and cement.
Eren Enerji tasked RJM to undertake a major review of its ZETES 2 unit 3* plant to identify how performance could be improved and emissions significantly reduced.
ZETES 2 unit 3, located at Zonguldak on the Black Sea, is a 615 MWe supercritical power plant. It is equipped with opposed-firing boilers and combustion technology featuring NR3 style burners supplied by Dongfang of China under licence from Mitsubishi Hitachi Power Systems.
ZETES 2 unit 3 came online in 2010 and fires local and imported bituminous coals.
Project objectives Although ZETES 2 unit 3 is a modern, supercritical
power plant equipped with Dongfang low NOx burners, it was experiencing unsatisfactory performance across a number of parameters. These included poor combustion and less than optimum boiler efficiency. In addition, the plant operators were seeking to protect the future life of the plant by avoiding tube leaks. With a proven track record in solving complex combustion and emissions challenges, the
ZETES 1, 160 MW; ZETES 2, 2 x 615 MW; ZETES 3, 2 x 700 MW. Unit 3 is one of the pair of 615 MW units that comprise ZETES 2.
