Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire. To prevent corrosion, nitrogen generators are used in place of or in conjunction with a compressed air system to provide supervisory nitrogen gas in place of air for dry pipe and pre-action fire sprinkler systems.
Gas generators of this type are used to power turbopumps in rocket engines, in a gas-generator cycle. It is also used by some auxiliary power units to power electric generators and hydraulic pumps. Another common use of the term is in the industrial gases industry, where gas generators are used to produce gaseous chemicals for sale. For example ...
Peak Scientific is a Scottish manufacturer of gas generators for analytical laboratories. [ 1 ] [ 2 ] [ 3 ] Headquartered in Glasgow , United Kingdom, it specialises in the production of nitrogen, hydrogen, and gas generators, mainly for the fields of liquid chromatography–mass spectrometry and gas chromatography .
~ mechanical load, e.g. electric generator. A closed-cycle gas turbine is a turbine that uses a gas (e.g. air, nitrogen, helium, argon, [1] [2] etc.) for the working fluid as part of a closed thermodynamic system. Heat is supplied from an external source. [3] Such recirculating turbines follow the Brayton cycle. [4] [5]
Liquid hydrogen is used by NASA in the Space Shuttle as a rocket fuel. A nitrogen generator Membrane nitrogen generator. Simpler gas separation technologies, such as membranes or molecular sieves used in pressure swing adsorption or vacuum swing adsorption are also used to produce low purity air gases in nitrogen generators and oxygen plants.
Here’s what garden and patio plants you can save for next spring. As the temperatures start to drop and sweater weather arrives, you may start to look sadly at your beautiful, lush garden plants.
The generators are usually ignited by a firing pin, and the chemical reaction is usually exothermic, making the generator a potential fire hazard. Potassium superoxide was used as an oxygen source on early crewed missions of the Soviet space program , in submarines for use in emergency situations, for firefighters , and for mine rescue .
But it's frequently used as the base of Christmas holiday cocktails. And the original eggnog recipes, which date back to the 1700s, included alcohol.
