Contract for flue gases denitrification installation in Kozienice Power Plant signed

Enea Wytwarzanie and RAFAKO signed a contract for the construction of a modern flue gases denitrification installation together with the modernisation of electrostatic precipitators in Kozienice Power Plant. The value of the contract is PLN 289.2 million net. The investment is planned to be completed at the end of 2018.

The subject of the contract is delivery and assembly of a modern installation of the catalytic denitrogenation of flue gases (SCR) together with replacement of flue gas ventilators for AP-1650 boilers on 9 and 10 power units, 500 MW each. RAFAKO will also execute the project and replacement of the electrostatic precipitator with ash removal system and corresponding flue gas channels, and will also modernise the flue gas desulphurisation plant (IOS) for unit no. 9.

The goal of the investment is guaranteeing an over five times reduction in the emission of nitric oxides from the current level of 500 - 550 mg/Nm^³ to the level of below 100 mg/Nm^³ NO_x.

Enea Wytwarzanie has been cooperating with RAFAKO for many years, and the first contract for the flue gases denitrification installation on units 4-8 was signed in 2011.

– Apart from the most important investment in a new, highly-efficient 1,075 MW power unit, we also take care so that the energy generated from current generating units is possibly the cleanest. The contracted installation for two 500 MW units will enable their further exploitation, since it will guarantee fulfilment of the strictest, current emission standards regulated in European directives, and also future, new standards specified in the BAT conclusions which will be in force as of 2021 – says dr Dawid Klimczak, acting president of Enea Wytwarzanie.

– We are happy that another large contract is found in our order portfolio. Experiences which we have gained in the recent years performing similar installations, precisely for Enea in Kozienice, allowed us for the preparation of a very good offer, mainly as regards the technical conditions. It proved again that RAFAKO’s competences within the environment protection installations are very high. We would like to thank our Partner for long cooperation and trust in us, demonstrated for the second time – says Agnieszka Wasilewska-Semail, president of RAFAKO.

SCR installation on boilers of units 9 and 10 will be performed in two stages. The first one covers the execution of the construction design, obtaining the building permit for the whole investment and realisation of the SCR installation on unit no. 9 with the ammonia water unloading and storing station (DRiM II). The first stage includes also the replacement of the electrostatic precipitator for unit no. 9. 85 weeks are foreseen for this stage of the contract execution. The second stage will include the SCR installation on unit no. 10 and connecting it to DRiM II. The completion of the second stage is planned for 25 August 2018. The final acceptance of the project is foreseen at the end of 2018.
