Abstract:
An air cooled heat exchanger, such as a combustion turbine intercooler or rotor cooler or an air cooled condenser, utilizes a pressurized gas fluid entraining misting device that evaporatively cools conduits carrying the cooled fluid medium. Evaporative cooling liquid is entrained in the pressurized gas where it is atomized for evaporative cooling of the heat exchanger conduits. In some exemplary embodiments of the invention the misting device is a jet pump or ejector that entrains a supply of non-pressurized cooling liquid. In other exemplary embodiments of the invention the misting device is a misting emitter that entrains a supply of pressurized cooling liquid.

Abstract:
Improvements to a portable media delivery system are disclosed. The improvements allow for frequent and simpler untrained and automatic self-servicing of a media delivery system. The improvements include an anti-bridging mechanism that fluffs, mixes or stirs the powder within the chamber to keep it in a liquefied state. Additional improvements include a larger opening to more quickly fill and inspect the powder within the chamber. Another improvement includes the use of a gas or CO2 canister located external to the chamber or reservoir to allow easier servicing or replacement of just the CO2 canister as well as the ability to maintain the chamber in an un-pressurized condition, allows for non-HASMAT shipping. These features will extend the service intervals while maintaining the media delivery system in a ready condition.

The present invention relates to a novel process for synthesizing nanomaterials by mixing liquids in a quasi-2D microfluidic reactor. The invention also relates to the reactor for implementing this process.
Abstract:
A spray system for spraying a secondary fluid into a primary fluid. The secondary fluid is gaseous, liquid or contains fine particulate solids to be dispersed in the primary fluid. The spray system has a central nozzle for the primary fluid and a nozzle for the secondary fluid. The nozzle housing has a tubular design and the central nozzle is provided with a central passage for the primary fluid. The passage, as seen in the flow direction, has convergent inlet region, a constriction and a divergent outlet part. An outlet opening for the secondary fluid is arranged on the downstream end of the nozzle housing and an outlet opening generates a spray jet of secondary fluid that surrounds the primary fluid exiting the central passage in a substantially ring-shaped manner.
Abstract:
The invention relates to a method or a system for coating substrates with at least one coating material which comprises at least one organic component, wherein the coating material is applied to the substrate by means of atomization and spray-painting. The invention is characterized in that the coating material is atomized by means of water vapor.The invention also relates to a system for coating substrates, wherein at least one nozzle arrangement (1) is provided in order to a atomize and spray the coating material onto a substrate, and at least one first supply device (8) which is used to prepare and supply the coating material to the nozzle arrangement (1), in addition to at least one second supply device (9) which is used to prepare and supply the steam as auxiliary gas to the nozzle arrangement (1).
Abstract:
An atomizer includes a T-shaped chamber with tapered insides and an outlet which is in communication with the chamber. A first path is located in a center area in the chamber so as to introduce molten metal therein and two second paths are introduced into the chamber so as to send inert gas into the chamber. A single diamond-shaped separator is located in the chamber and located at an outlet end of the first path. A narrow passage is defined between an inside of the outlet and the separator. The impact of the inert gas and the molten metal atomizes the metal.
Abstract:
A method for generating an aerosol includes the step of guiding a gas which flows at supersonic velocity and which has input particles suspended therein in such a way that a compression shock occurs. The input particles are broken down into smaller output particles upon crossing the compression shock. A device for generating an aerosol is also provided.
Abstract:
Gas-assisted atomizing devices are provided that include liquid orifices, which release liquid, and gas orifices, which release gas to atomize the liquid into droplets. The atomizing devices are formed by at least a first layer and a second layer. The atomizing devices can include a gas supply network and a liquid supply network that supply gas and liquid to the gas and liquid orifices.
