摘要:
A heat storage tank comprising an envelope (2) with a longitudinal axis (X) filled with a heat transfer liquid and solid heat storage elements, a first longitudinal end fitted with first means (10) for collecting and supplying a liquid at a first temperature and a second longitudinal end provided with second means (12) for collecting and supplying a liquid at a second temperature, in which said solid heat storage elements are distributed across three beds (TH1, TH2 and TH3) superposed along the longitudinal axis (X), separated by a layer of liquid (L1, L2 and L3), the heat transfer liquid being capable of flowing from the first longitudinal end to the second longitudinal end.

Solar power station comprising a first exchanger (MCPT1) positioned downstream of the exit from the solar field (CS) and upstream of the storage system (RTH) and of the conversion system (TU) such that all the hot fluid leaving the solar field (CS) circulates through said at least one first exchanger (MCPT1) before feeding into the conversion system (TU) and/or the storage system (RTH), said first exchanger (MCPT1) comprising a phase-change material the phase-change temperature of which is a temperature slightly below that of the nominal operating temperature (T1) of the conversion system (TU).
摘要:
A method for filling a heat storage tank with solid elements having at least one first particle size and one second particle size, the first particle size being greater than the second particle size, said method comprising the following steps: a) pouring a first quantity of solid elements of the first particle size into the tank, b) levelling said first quantity of solid elements of the first particle size so as to form a layer of a substantially constant height, c) pouring a second given quantity of solid elements of the second particle size over the layer of solid elements of the first particle size such that the solid elements of the second particle size flow between the solid elements of the first particle size and such that the elements of the second particle size are flush with the layer of the solid elements of the first particle size and so as to form an intermediate layer.
摘要:
The invention relates to a heat regenerator, which includes at least one matrix made of a refractory material in order to ensure the storage and recovery of heat. Said matrix includes at least one through-channel (2) capable of enabling the circulation of a fluid, said channel comprising at least two projections (3) projecting into the space defined by said channel, said projections being positioned on two opposite surfaces of the channel.
摘要:
The invention relates to an absorber (6) for a solar receiver comprising a housing (12) having a longitudinal axis (X) including a first longitudinal end (18.1), a supply collector (20) for supplying a heat transfer fluid to a second longitudinal end (18.2), a discharge collector (22) for discharging said fluid, the housing comprising a first wall (14.1) provided with a surface (6.1) to be exposed to a luminous flux (F), a second wall (14.2) facing the first wall, side walls (16.1, 16.2) connecting said first (14.1) and second walls (14.2), said housing (12) comprising a means (28) which rigidly connects the first and second wall, and is formed by at least one longitudinally extending rib (30) attached to the first (14.1) and to the second (14.2) wall, said rib (30) comprising the windows (32) and the deflectors (34) associated with the windows (32), said deflectors (34) requiring a portion of the fluid to pass through said windows (32) causing a remixing of the fluid.
摘要:
Device for storing heat in the form of latent heat comprising a reservoir (102) containing a phase-change material, two heat exchangers (104, 106) arranged outside the reservoir (102), the phase-change material being inside the reservoir, at least at the start of a phase change, partly in a solid phase forming an agglomerate (MCPS) situated in the bottom of the reservoir (2), said device comprising: - means (122) that create a circulation path in-between the agglomerate (MCPS) and the reservoir (102) so as to cause a circulation of liquid phase-change material between the agglomerate (MCPS) and a wall of the reservoir (102), and - means (124) that cause the volume of agglomerate (MCPS) to break up and produce chips of phase-change material to form a solid-liquid mixture circulating toward the heat exchangers.
