Combined heat and power plant at Arctic Paper Kostrzyn, Poland

Production of paper requires the electric energy and process steam that are used in a paper stock preparation process and next in paper web drying on paper machines. For this reason, an integral part of a mill is an own combined heat and power plant. Operated at present, more than 40 years old, the coal-based CHP Plant has reached its maximum production capacity and, apart from inability to satisfy the environment protection requirements, is a barrier for further development of the Paper Mill. Based on carried out analyses, the concept of erecting the new CHP Plant, making use of the natural gas from local resources situated in Lubuskie and Zachodniopomorskie Provinces, has been chosen. The project is of the key importance for the Company since it decides about the possibility of further development of the Mill. Since the process of energy production is to be changed, it is necessary to install new equipment for gas combustion, new power installations and auxiliary devices.

Technical description
R&V has designed a supplementary firing system firing both natural gas and process waste gas simultaneously on a single burner system. The fuel systems providing the fuel supply to the burners have also been designed and manufactured by R&V Engineering.
