Title
(EN) CONCENTRATED SOLAR POWER SOLIDS-BASED SYSTEM
(FR) SYSTÈME À ÉNERGIE SOLAIRE CONCENTRÉE À BASE DE MATIÈRES SOLIDES
Abstract
(EN)
A solar power system comprises a solar receiver, a heated solids storage tank downstream of the solar receiver, a fluidized bed heat exchanger downstream of the heated solids storage tank, and means for transporting solid particles from the fluidized bed heat exchanger to a cold solids storage tank upstream of the solar receiver. The fluidized bed heat exchanger includes a first fluidized bed and a second fluidized bed. Solid particles flow through the fluidized bed heat exchanger and transfer heat energy to heating surfaces in the two fluidized beds. The system permits the solid particles to absorb more energy and permits a constant energy output from the fluidized bed heat exchanger.

L'invention concerne un système à énergie solaire comprenant un récepteur solaire, un réservoir de stockage de matières solides chauffées en aval du récepteur solaire, un échangeur de chaleur à lit fluidisé en aval du réservoir de stockage de matières solides chauffées, et des moyens destinés à transporter des particules solides de l'échangeur de chaleur à lit fluidisé à un réservoir de stockage de matières solides froides en amont du récepteur solaire. L'échangeur de chaleur à lit fluidisé comprend un premier lit fluidisé et un second lit fluidisé. Les particules solides circulent à travers l'échangeur de chaleur à lit fluidisé et transfèrent l'énergie calorifique aux surfaces de chauffage dans les deux lits fluidisés. Ce système permet aux particules solides d'absorber plus d'énergie et permet une émission d'énergie constante par l'échangeur de chaleur à lit fluidisé.
