Objective Foreseen ResultsSuccessful realization of the project will allow to implement a new-generation of heavy-duty process vessel windows H for the Electron Beam Dry Scrubber Process, first at the Pomorzany Power Station and then in other installations of this type in Europe.Further challenge left for surface engineering scientists will be to reduce the window thickness. As the project addresses the environmental problems it is of importance in european dimension.High emissions of SO2 and NOx from fossil fuel combustion create a major environmental problem all over the Europe. One of the most perspective methods of these pollutants removal is the Electron Beam Dry Scrubber Process, in which the flue gas is treated by high-power, high-energy electron beam. The final product obtained in this process can be used as a fertilizer.In Poland, a pilot industrial installation utilizing this process with a throughput of 20.000 Nm3/h has been built at Kaweczyn Power Station in Warsaw to study and develop this process. Another one, designed for treating of 270.000 Nm3/h of flue gases in under construction at Pomorany Power Station near by Szczecin.The electron beam enters the process vessel through a 50mm thick Ti window. At present, the lifetime of this window is 500 - 2000 h before it fails as a result of corrosion and fatigue. For full industrial implementation the window lifetime should span over the installation overhauling period. The objective of the project is to develop a technology of preparing the window of the desired lifetime. This goal is planned to be accomplished by alloying the window surface with palladium which is known to inhibit Ti corrosion in acidic environment. The alloying will be performed either by ion-beam mixing technique known to be thus far the most effective approach or by ion beam assisted deposition (IBAD). As a supplementary measure, nitrogen ion implementation will be used to increase the fatigue strength of the window material, titanium alloy as material for window will be examined, and entirely new approach of deposition by pulsed plasma beams will be explored.After performing laboratory and field tests of various versions of the presented technologies, a final approach will be chosen and then a full size window will be manufactured and next tested at the Kaweczyn Power plant.
