Enriched O2 burning and smelting technologyPlant capacity10 15000Nm3/h Enriched O2 burning technology is the technology of fully burning coal and O2 after purifying oxygen. This technology can improve the combustion heat value of coal, reduce emissions, and can play the role of energy-saving emission reduction The company self-developed vacuum pressure swing adsorption (VPSA) producing enriched O2 technology is small investment, low energy consumption and running expense saving technology. It has passed the identification of high-tech achievement by the ministry of chemical and metallurgy, and widely applied in nonferrous smelting, steel, chemical, papermaking, glass fiber and so on. Technical features 1. Adopt the company self-developed and produced new type oxygen molecular sieve: low investment, save energy consumption, electricity consumption per unit oxygen production is 0.260.38kwh/Nm3 O2, circulating water consumption per unit enriched oxygen is 0.002t/Nm3O2, oxygen recovery rate can be 67% above. 2. oxygen purity can be adjusted between 25 95%, the unit has strong adaptability, the output can be regulated under the load of 25-110of rated production capacity. 3. Short process flow, highly automated, and convenient for startup and shutdown.
