  • Heat exchangers that contain and utilize fluidized small solid particles
    Patent number: 6698501
    Abstract: Heat exchangers utilizing flat surfaced passages to contact, contain and utilize fluidized small solid particles is provided. Top and bottom woven wire mesh or perforated sheet corrugated with rounded or flat-sided ridges are attached to respective top and bottom sides of said passage to increase its surface and to prevent said small solid particles from exiting said heat exchanger. A variety of shapes of the small solid particles are provided to further enhance the heat transfer rate. More energy efficient systems of all kinds will result from the use of these smaller heat exchangers.

  • Plates perforated with venturi-like orifices
    Patent number: 5918637
    Abstract: Plates that are perforated with two or more venturi orifices that have "C.sub.d " discharge coefficient values that are greater than 1.0. The venturi orifices to be used can be made in an infinite number of tubes that have a converging entrance, a throat, and a diverging discharge. The plates are to be used to make improved devices to be used in fluid flow streams.
