In December 2010 the Management Board of Remak-Rozruch S.A., in consortium with Nalco Mobotec Polska Sp. z o.o., signed, with the Management Board of ZE PAK S.A., a contract for the modernization of OP650b coal-fired pulverized-fuel boiler to reduce nitrogen oxides emissions in Unit no 5 of Pątnów Power Plant.

This agreement included installation of the system to reduce NOx emission on the boiler of Unit 5, based on following technologies: ROFA (primary method) and Rotamix (secondary method), patented by Nalco Mobotec. The scope of works also carried out a number of other modifications, both the boiler and the auxiliary systems, including control and combustion system in the boiler. The works were carried out in all sectors as a turnkey project. 

The aim of the project was to obtain the parameters required by the Investor, that is mainly reduction of nitrogen oxides to less than 180 mg/Nm3, as well as increasing the thermal efficiency of the boiler.

Construction of biomass system for K3 and K9 boilers in EC-3 Dalkia Łódź


In October 2010 a contract was signed between the management of Remak-Rozruch S.A. and Dalkia S.A. for the execution of the process system for pellets unloading and storage, as well as biomass powder preparation from pellets and biomass powder feeding  in the total quantity of 20 t/h to OP230 boilers K3 and K9 indicated by Dalkia Łódź in EC-3 Łódź (Łódź CHP Plant 3).

 The scope of the contract includes end-to-end erection of the systems, from civil and construction works at the biomass unloading and storage building, through the powder conveying system up to the burners. The works also include installation of the entrance truck scale and construction of access roads.

 In the recent years the growing interest of power generating facilities in biomass utilization in the combustion process has been observed. The reason of that are numerous benefits related to biomass firing, among others: low costs of power generation, lower fees for the use of the environment, effective utilization of bio-waste, as well as possibility to obtain the financial support under ecological funds.
