Techno-economic and operational assessment of concentrated solar power plants with a dual supporting system
(Elsevier, 2021-11)
This study evaluates the benefits of integrating a full renewable dual back-up system (biomass and Thermal Energy Storage (TES)) in Concentrated Solar Power (CSP) plants. Two plants of 50 MWe capacity each are modelled ...

Tar conversion of biomass syngas in a downstream char bed
(Elsevier, 2020)
The catalytic conversion of biomass-derived tars over char during long tests (over 6 h) is studied. The syngas is generated in a steam-blown fluidized-bed gasifier employing wood pellets and conducted to a second tubular ...

On the comprehension of the gas split in loop seal devices
(Elsevier, 2022)
Gas distribution through the chambers of a loop seal in circulating fluidized bed (CFB) units is still difficult to predict and often misunderstood. Dedicated experiments were carried out in an isolated loop seal to assess ...

Change of existing circulating fluidized bed boilers to oxy-firing conditions for CO2 capture
(Elsevier, 2021-12)
This work investigates a circulating fluidized bed boiler, originally designed for air-firing, retrofitted to oxy-firing with the purpose of removing the CO2 emission from coal combustion. Previous studies have shown that ...

Fluid dynamic analysis of dual fluidized bed gasifier for solar applications
(Elsevier B.V., 2021)
A hydrodynamic model of a dual fluidized bed gasifier (DFBG) is developed and its predictions are compared with measurements of solids flux and pressure profiles from a cold flow model (CFM). Then, the performance of a ...

Facing the high share of variable renewable energy in the power system: Flexibility and stability requirements
(Elsevier, 2022-03)
Power systems with a high share of variable renewable energy (VRE) represent a challenge to system operators because of the increased flexibility requirements and stability. This study analyses the performance of a real ...
