State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
An air well or aerial well is a structure or device that collects water by promoting the condensation of moisture from air. [1] Designs for air wells are many and varied, but the simplest designs are completely passive, require no external energy source and have few, if any, moving parts.
The organized collection of dew or condensation through natural or assisted processes is an ancient practice, from the small-scale drinking of pools of condensation collected in plant stems (still practiced today by survivalists), to large-scale natural irrigation without rain falling, such as in the Atacama and Namib deserts.
Condensate pumps may be used to pump the condensate produced from latent water vapor in any of the following gas mixtures: Conditioned (cooled or heated) building air; Refrigerated air in cooling and freezing systems; Steam in heat exchangers and radiators; The exhaust stream of very-high-efficiency furnaces
An oil burner is a part attached to an oil furnace, water heater, or boiler. [1] It provides the ignition of heating oil/biodiesel fuel used to heat either air or water via a heat exchanger . The fuel is atomized into a fine spray usually by forcing it under pressure through a nozzle which gives the resulting flame a specific flow rate, angle ...
The diagram shows a typical reflux apparatus. It includes a water bath to indirectly heat the mixture. As many solvents used are flammable, direct heating with a Bunsen burner is not generally suitable, and alternatives such as a water bath, oil bath, sand bath, electric hot plate or heating mantle are employed. [6]
Water usually contains some dissolved air, and boiling the water released this with the steam. This air could not be condensed by the water spray and gradually accumulated until the engine became "wind logged". To prevent this, a release valve called a "snifting clack" or snifter valve was included near the bottom of the cylinder.
An air-cooled condenser is however, significantly more expensive and cannot achieve as low a steam turbine exhaust pressure (and temperature) as a water-cooled surface condenser. Surface condensers are also used in applications and industries other than the condensing of steam turbine exhaust in power plants.
