  • Patent number: 11730311
    Abstract: A mixing apparatus is described. The mixing apparatus has a first port for receiving milk, a second port for receiving steam, and a mixing chamber for mixing the milk, the steam, and air. A channel arrangement connects the first port and the second port, and defines an air intake channel which leads to a frothing section. The mixing apparatus is designed such that, in use, the frothing section fills sufficiently with steamed milk that has a direct path from the second port to the mixing chamber is interrupted by the steamed milk. This provides a noise reduction during use of the mixing apparatus. A flow reducing means, such as a barrier, may be used for this purpose.

    Abstract: A distillation tower for use in a petrochemical or petroleum operation effects liquid and vapor separation by using centrifugal force applied to the feed introduced into a ring from a tangential inlet. The feed is separated into a liquid component that flows into the bottoms section of the tower and a vapor component that flows upwardly through the core of the ring to a wash zone in the tower. De-entrainment devices are provided in the core so that the vapor swirling upwardly impacts the devices and any remaining entrained liquid is separated from the vapor. As a result, overflash with decreased resid can be collected from the wash zone and used as feed suitable for a fluid catalytic cracking operation, for example.

Each slot has one edge configured with a vane that creates turbulence in the air/fuel mix passing through the adapter so that larger droplets are broken up into smaller droplets until an optimum droplet size is reached.

  • Publication number: 20040021235
    Abstract: Disclosed is a unique fuel and air premixing system for a gas turbine catalytic combustion system. The mixer utilizes a multi-channel counter-rotating swirler with aerodynamically shaped fuel pegs located upstream of the swirler. The premixing system provides the downstream catalyst with a fuel-air mixture sufficiently uniform for proper catalyst operation and wide operating limits. Features have been incorporated in the system to make it resistant to flameholding.

  • Patent number: 6648306
    Abstract: This disclosure relates to a centrifugal vortex system for preparing a liquid, such as fuel and includes a chamber housing defining a vortex chamber. An array of tangential apertures are formed in the chamber housing to permit fluid to be turbulently introduced into the vortex chamber to create a vortical flow of fluid through the vortex chamber. In one embodiment, a plurality of vortex chambers are arranged in series to allow the fluid to pass through several vortex chambers. In other embodiments, the chamber housing may be stepped, textured, or both to increase the turbulence of the flow through the chamber. In yet another embodiment, a pressure differential supply jacket is provided to normalize the amount of flow through the tangential apertures according to the location of the apertures. A centrifuge chamber is also disclosed which has a plurality of output conduits on a bottom surface and a tapered extension member downwardly extending from a top surface to enhance the centrifugal flow of the fluid.

  • Publication number: 20030155666
    Abstract: The present invention promotes atomization and vaporization of spray at the time of cold startup and reduces the amount of fuel depositing on the inner wall of the intake manifold, thereby ensuring improved startability of an internal combustion engine of a car, reduced fuel costs and improved purification of exhaust gas. A very fine groove 201 is formed on a heat transfer surface 76 in a fuel vaporization promoting apparatus 100, wherein this groove 201 is shaped in such a way that fuel 24 is dispersed by the surface tension of a heat transfer surface 76 and fuel 24.
