These drawings show how much heat is required to generate one pound of steam. at 100 pounds per square inch pressure. Note the extra heat and higher temperature required to. make water boil at 100 pounds pressure than at atmospheric pressure.
An Oxygen Concentrator uses this idea with the basic principle of Pressure Swing Adsorption (PSA) to deliver 90-95% pure oxygen. 1  Series of filters: To filter out impurities present in air.  Air Compressor: To push room air into the machine and forward it to the molecular sieve beds.
Â­ThÂ­e oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The mechanism in most sensors involves a chemical reaction that generates a voltage (see the patents below for details).
