Ecoenergia will participate in the project focused on modernization of the boiler house containing two PTWM-100 boilers operated by Siekierki cogeneration plant. The contract is aimed at conversion of mazout fired boilers (K8 and K9) into Ekoterm light oil units.
Within the framework of the contract signed on 20 November 2013, Ecoenergia will be responsible for preparation of technical documentation and supply of combustion equipment that will enable the boilers to meet the IED Directive SO2, NOx and dust emission limits that will become obligatory in the year 2016. The boilers will be modernized successively: K8 unit in 2014 and K9 in the year 2015.
