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.
The sulphur denitrator works by creating an anaerobic (zero oxygen) condition inside the filter, where anaerobic bacteria will grow and process the nitrate to nitrogen.he sulphur denitrator works by creating an anaerobic (zero oxygen) condition inside the filter, where anaerobic bacteria will grow and process the nitrate to nitrogen.
