摘要:
The present invention concerns a device for collecting solar energy by means of a concentrator (12) of the nonimaging type and a receiver (3) for the transfer of energy by heat exchange with a fluid which operates, independently, a thermodynamic cycle for the exploitation of energy, said concentrator (12) comprising an inlet area (1), an underlying outlet area (2) and an inner space between said inlet area (1) and said outlet area (2); said receiver (3) being positioned under said concentrator (12) and said inner space of the concentrator (12) and said receiver (3) being connected by said outlet area (2), characterised in that said inner space of the concentrator (12) and said receiver (3) are in fluid communication through said outlet area (2), a plurality of solid particles (11) are present inside said receiver (3), and said device for collecting solar energy comprises means (6) apt to take a part of said solid particles (11) from said receiver (3) and to put them from below inside said inner space of said concentrator (12), said solid particles (11) subsequently returning, by gravity, into said receiver (3), passing through said outlet area (2).

The cooling coils used in a commercial oxidation or ammoxidation reactors can be made more closely packed by providing the individual courses defining the cooling coil in a transverse arrangement rather than a linear alignment.
摘要:
A method to use high temperature thermal storage for integration into building heating/cooling systems and to meet building's peak power demand. The method can be used to store the thermal energy at any desirable rate and then discharge this stored energy to meet the demand for short or long time intervals. Input energy stored with this method is thermal energy, however, output can be thermal or electric based upon the requirement.
摘要:
The present invention relates to an immersed heat transfer tube installed in a fluidized bed of a fluidized-bed boiler for recovering combustion heat generated when a fuel such as RDF (refuse derived fuel) with high calorific value containing biomass and plastics, or wastes is combusted. An immersed heat transfer tube (5) which is installed in a fluidized bed (3) of a fluidized-bed boiler (1) includes a water tube (6) through which a fluid flows, a cylindrical protector (8) provided at an outer circumferential side of the water tube (6) and configured to protect the water tube (6), and a packed bed (7) provided between the water tube (6) and the protector (8).

Eine Vorrichtung zum Temperieren von Schüttgut (20) weist einen in Schwerkraft-Richtung vom Schüttgut (20) durchströmbaren Wärme-Austausch-Abschnitt (2), einen diesem vorgeordneten Puffer-Abschnitt (1) und einen ihm nachgeordneten Austrags-Abschnitt (3) auf. Dem Austrags-Abschnitt (3) ist eine Austrags-Einrichtung (22) zugeordnet. Weiterhin ist eine Überlauf-Rohrleitung (27) für das Schüttgut (20) vorgesehen, deren Eintritts-Öffnung (29) aus dem Puffer-Abschnitt (1) ausmündet, und die mit dem aus dem Austrags-Abschnitt (3) ausgetragenen Schüttgut (20) wieder zusammengeführt ist.
摘要:
An apparatus for carrying out a physical and/or chemical process, such as a heat exchanger, comprising a fluidized bed through which a fluid flows, and a separator for separating fluidized bed particles from the medium for recirculation. The apparatus comprises a reservoir provided with upwardly directed tubes, which tubes are provided, according to the invention, with run-out pieces with separation openings, provided in the tube wall, for separating therethrough a partial flow of medium. The invention also relates to a method for carrying out a physical and/or chemical process.
