Abstract

A method is provided for heat transfer between a granular material (14) capable of forming a moving bed, and a fluid (15). The method includes filling with said granular material (14) a cylindrical chamber (2) of which the longitudinal axis (XX′) extends horizontally in the configuration of use, supplying the chamber (2) with fluid via at least one cylindrical fluid-receiving tube (3) arranged at least partially inside the chamber (2) and rotating the chamber (2) about an axis coincident with the longitudinal axis (XX′) of the chamber (2). The tube (3) is coaxial with the longitudinal axis (XX′) of the chamber (2) and opens at each of its ends to outside the chamber (2) so as to be able to be connected to a fluid circulation circuit (5) and the filling of the chamber (2) with the granular material (14) involves filling up to a height of fill (H) within the range of heights defined by the formula: R + a × R ⁢ 1 where R corresponds to the interior radius of the cylindrical chamber (2) and R1 to the interior radius of the cylindrical fluid-receiving tube (3) and a is comprised between 0 and 1.

Dependent claims

A method for heat transfer between a granular material capable of forming a moving bed, and a fluid, said method comprising:

when a cylindrical chamber is in a configuration referred to as the configuration of use in which the longitudinal axis of said chamber is extending horizontally:
filling said chamber with a volume of granular material corresponding to the moving bed that is to be formed,
supplying said chamber with fluid via at least one cylindrical fluid-receiving tube arranged at least partially inside the chamber and
rotating said chamber about an axis coincident with the longitudinal axis of the chamber, wherein the cylindrical fluid-receiving tube is a fixed tube coaxial with the longitudinal axis of rotation of the chamber and opens at each of its ends to outside the chamber so as to be able to be connected to a fluid circulation circuit and in that the volume of granular material serving to form the moving bed in the cylindrical chamber corresponds to the filling of the chamber with granular material to a height of fill comprised within the range of heights defined by the formula:

where R corresponds to the interior radius of the cylindrical chamber and R1 to the interior radius of the cylindrical fluid-receiving tube and a is comprised between 0 and 1, this height of fill corresponding to the level of granular material in the chamber when the granular material is evenly distributed through the chamber and has been leveled.

A facility for heat transfer between a granular material capable of forming a moving bed, and a fluid, said facility comprising a cylindrical chamber having a configuration of use in which the longitudinal axis of the chamber extends horizontally, and in which said chamber is capable of being filled with a volume of granular material corresponding to the moving bed that is to be formed, at least one cylindrical fluid-receiving tube arranged at least partially inside the chamber and a rotational-drive system for rotating the chamber about an axis coincident with the longitudinal axis of the chamber, wherein the fluid-receiving tube is a fixed tube which is arranged coaxial with the longitudinal axis of rotation of the chamber and which opens at each of its ends to outside the chamber so as to be able to be connected to a fluid circulation circuit, and in that the volume of granular material serving to form the moving bed in the cylindrical chamber corresponds to the filling of the chamber with granular material to a height of fill comprised within the range of heights defined by the formula

R+a×R1, where R corresponds to the interior radius of the cylindrical chamber and R1 to the interior radius of the cylindrical fluid-receiving tube and a is comprised between 0 and 1, this height of fill corresponding to the level of granular material in the chamber when the granular material is evenly distributed through the chamber and has been leveled.
