Abstract: The high velocity and high dilution exhaust system uses a centrifugal fan provided with a tapered nozzle. The nozzle compresses the airstream exiting the fan to increase back pressure and velocity. The air flow from the fan enters a stack having a venturi further increasing the velocity and decreasing the pressure. The decrease in pressure causes a suction, allowing the introduction of ambient air to mix with and dilute the output of the fan. The total discharge from the exhaust stack has a high velocity resulting in a plume height and effective height of the exhaust before dispersion occurs.

Abstract: The present invention relates generally to an exhaust gas back pressure attenuator for truck exhaust stacks. In particular, the present invention is directed toward an improved exhaust gas deflector that reduces the back pressure within the vertical tubular exhaust stacks of over-the-road type tractor-trailer trucks. At highway speeds a number of factors may operate to make it difficult for the engine to force exhaust gas out of the system and into the atmosphere. The present invention is attached to the top of the stack and is designed to create an aerodynamic low-pressure condition that in effect pulls the exhaust gas from the stack, thereby reducing back pressure buildup, decreasing the load on the engine, and increasing the fuel efficiency. A first embodiment of the present invention employs an air wedge to divide a first ambient air volume and cause it to pass on either side of the exhaust stack, thereby creating a pressure differential which operates to pull the exhaust gases thereout.

Abstract: In a method and apparatus for lifting gas streams, vertical streams of air and/or gases of a great height are artificially formed in the atmosphere, mainly for decontamination purposes, by heating the air throughout a circular area sufficient to produce a shaft effect, so as to form an ascending column of air and/or gases. The air and/or gases are then driven within the column to produce a rotatory movement thereof to form a vortex. Once a column of a sufficient height has been formed, the rotatory driving action on the air and/or gases is interrupted while the heating thereof is maintained so that the vortex is maintained by the lifting force induced by heat.
