Oxygen is the substance that all living organisms on earth depend on. It is easy to form oxides by chemical reaction with other substances, and a lot of heat will be produced in the process of oxidation reaction. Therefore, oxygen as oxidant and combustion supporting agent has been widely used in metallurgy, chemical industry, energy, machinery, national defense industry and other sectors. The economy of oxygen generator mainly refers to the cost of producing unit product (per m³ of oxygen). The cost includes power consumption, water consumption, oil consumption, steam consumption, auxiliary material consumption, maintenance cost and production management cost. In order to improve the operation economy of oxygen generator, we should strive to produce more products and reduce the production cost.
