Abstract
An apparatus and method for the horizontal conveying of a dry powder is provided, notably useful for conveying heat from a heat-producing operation to a heat-consuming operation. In this application, heat is conveyed by a hot powder flowing through a vertically vibrated duct, the intensity of the vibration being sufficient to place the powder in a liquid-like state. The flow of powder is accompanied by a fall in pressure, and there is included a step for raising the pressure of the powder.
Claims10
Apparatus for delivering heat from a heat-producing operation to a heat-consuming operation separated horizontally one from another, comprising:
- a powder;
- means for heating said powder in said heat-producing operation;
- a duct for conveying heated powder from said heat-producing operation to said heat-consuming operation and means for introducing said heated powder into said duct;
- means for cooling said powder in said heat-consuming operation;
- a duct for conveying cooled powder from said heat-consuming operation to said heat-producing operation and means for introducing said cooled powder into said duct;
- means for vibrating said two ducts, the vibration including a vertical component at a vibrational intensity sufficient to place said heated or cooled powder in a liquid-like state, the pressure of said powder falling in said two ducts;
- and
- means for raising the pressure of said powder to compensate for said fall in pressure in said two ducts.
Apparatus for conveying a dry powder horizontally, comprising:
- a horizontal duct;
- means for introducing said powder at a first pressure into a first end of said duct;
- means for vibrating said duct, the vibration including a vertical component at a vibrational intensity sufficient to place said powder in a liquid-like state;
- means for withdrawing said powder at a second pressure from a second end of said duct, wherein said second pressure is below said first pressure;
- means for raising the pressure of said powder from substantially said second pressure to substantially said first pressure.
A method for delivering heat from a heat-producing operation to a heat-consuming operation separated horizontally one from another, comprising:
- heating a powder in said heat-producing operation and introducing said heated powder into a duct extending from said heat-producing operation to said heat-consuming operation;
- cooling said heated powder in said heat-consuming operation and introducing said cooled powder into a duct extending from said heat-consuming operation to said heat-producing operation;
- vibrating each of said two ducts, the vibration including a vertical component at a vibrational intensity sufficient to place a powder situated within said ducts in a liquid-like state, the pressure of said powder falling in said two ducts;
- and
- raising the pressure of said powder to compensate for said fall in pressure in said two ducts.
A method for conveying a dry powder horizontally, comprising:
- vibrating a horizontal duct, the vibration comprising a vertical component having a vibrational intensity sufficient to place a dry powder situated within said duct in a liquid-like state;
- introducing said dry powder at a first pressure at a first end of said duct;
- withdrawing said powder at a second pressure at a second end of said duct, wherein said second pressure is below said first pressure;
- raising the pressure of said powder from substantially said second pressure to substantially said first pressure.
