Description du projet
Réduire la corrosion dans les centrales électriques fonctionnant à la biomasse
Le monde se tournant vers des alternatives aux solutions à base de combustibles fossiles, le nombre de chaudières de centrales électriques alimentées par de la biomasse est en hausse. Toutefois, l’un des problèmes graves auxquels sont confrontées les centrales à biomasse est l’importante corrosion des chaudières. Le projet BELENUS, financé par l’UE, adoptera une approche globale pour résoudre cette question. Des méthodes d’ingénierie de surface optimiseront les performances des matériaux, de nouvelles méthodes de soudage pour les tuyaux galvanisés amélioreront la qualité des éléments de la chaudière et un suivi en ligne de la corrosion permettra d’évaluer les conditions de corrosion. L’objectif final consiste à renforcer l’efficacité de conversion de la biomasse et à prolonger la durée de vie de la centrale à biomasse. En cas de succès, le projet prévoit de réduire le capital bioénergétique et les dépenses opérationnelles de 5 % et 60 %, respectivement.
Objectif
The primary objective of BELENUS is to lower bioenergy CAPEX and OPEX by an average of 5 and 60% respectively. This will be addressed by preventing or mitigating corrosion as the main limiting factor through a holistic approach to prevent corrosion in the boiler, in particular in superheater (SH) tubes: a) new surface engineering: biomass corrosion highly resistant coatings on creep resistance materials; b) new strategies of welding and bending for coated tubes improving the quality and efficiency of boiler components; and c) new online corrosion monitoring system specifically designed for biomass CHP plants. In addition, the BELENUS solution will impact on other LCOE parameters by improving efficiency in the conversion (up to 42%), increasing a 5% the operational hours of the plant and plant life time (5 years) and reducing the fuel expenditure of the plant by optimising its use and providing flexibility by allowing the use of different types of biomass. Improved performance for high temperature material systems through the technological breakthroughs, will be evaluated and validated an innovative test protocol. Finally, modelling and lifetime prediction tools will be developed and cost analysis and Life Cycle Analysis (LCA) undertaken so the optimum materials and coatings are chosen from the durability, economic and environmental perspectives, maximising the sustainability in economic and environmental terms. BELENUS brings together a multidisciplinary consortium comprising the main stakeholders with leading utilities, steel and tube developers, boiler designer and specialized research institutions from across Europe. This synergy allows a direct transfer of results in TRL5 to be obtained in BELENUS as technical base to go further to higher TRL into commercial biomass electric power plants within less than 5 years.
