The power plant, of about 400 MW of power, is a high-performance plant with a low environmental impact. PLANT CONSTRUCTION VIDEO TURBINE TRANSPORT VIDEO Knowing the energy

contacts glossary faq link NEWS ARCHIVE PRESS RELEASES PLANT CONSTRUCTION VIDEO REMIT HOME / ENVIRONMENTAL EFFECTS / ATMOSPHERE EFFECTS The plant has two sources of emission into the atmosphere: one continuous and one discontinuous. The continuous emission source is constituted by the chimney of the recovery boiler, while the discontinuous one is constituted by the chimney of the auxiliary boiler. The two fireplaces are grouped in a single 60 meter high structure, in order to reduce the visual impact. The auxiliary boiler is used only in the start-up phase of the turbogas turbine. The fumes from the steam generator are sent to the chimney at a temperature not higher than 105 ° C and at a speed of not less than 20 m / s. The flue gas flow rate to the chimney, at full power, will be approximately 633 m 3 / s. The emissions of the gas turbine plant are essentially limited to CO 2 - carbon dioxide , to a limited extent compared to other conventional plants - CO - carbon monoxide - and NOx - nitrogen oxides . The system used in the San Severo power plant to reduce atmospheric emissions acts at the "source", avoiding the production of pollutants, directly inside the gas turbine. The use of an advanced technology combustion system, without water injection - Dry Low NOx (DLN) - allows the containment of NOx and CO emissions. This process, identified by the European Union as one of the BAT (Best available Technologies - best available techniques), in terms of overall energy yields and the possibility of containing pollutant emissions into the atmosphere, is based on the pre-mixing of air and gas. in such a way as to optimize combustion and reduce emissions to concentrations below 25 parts per million.
