Descripción del proyecto
Reducción de la corrosión en las centrales de biomasa
A medida que el mundo se pasa a las alternativas a las soluciones de combustibles fósiles, crece el número de calderas de centrales con combustión de biomasa. Sin embargo, un grave problema que afrontan las centrales de biomasa es la grave corrosión de las calderas. El proyecto BELENUS, financiado con fondos europeos, adoptará un enfoque holístico para solucionar este problema. Los métodos de ingeniería de superficies optimizarán el rendimiento del material, los nuevos métodos de soldadura para los tubos revestidos mejorarán la calidad de los componentes de la caldera y un control en línea de la corrosión ayudará a evaluar el estado de corrosión. El objetivo final es mejorar la eficiencia de conversión de la biomasa e incrementar la vida útil de la central de biomasa. Si lo logra, el proyecto estima reducir los gastos de capital y operativos de la bioenergía un 5 y un 60 % respectivamente.
Objetivo
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.
