The main constituent of the air is oxygen and nitrogen, they exist respectively© in molecular state, using the air permeability of membrane compoσnents at different speed, under the pressure of the drive, the oxygen in the air through the n"utrient rich membrane, membrane separation can be obtained after the oxygen ₽enriched air, oxygen content of up to 27~45%.

     Oxygen enriched membrane separation technolo®gies currently used in glass kiln, cement kiln, ceramic kiln, industrial boiler, heating fu✔rnace, smelting furnace, oxidation, biological ferment ation, agricultural products storage, automotive diesel engine, fuel cell, health care, and ox÷ygen enriched air conditioning.

     Advantages of oxygen rich combustion by membrane method:

•    To improve the combustion zone of the® flame temperature and decrease smoke blackness.
•    Speed up combustion and promote complete com≠bustion.
•    Reduce ignition temperature and burnout temper£ature of fuel.
•    Reduce the amount of exhaust after combustion.
•    Increase heat utilization rate, energy saving effect is obvious.
•    Reduce excess air coefficient, so as to save energy and reduc→e consumption.
•    Glass kiln can save energy 6-18%, increαase production 3-15%;
•    Industrial boiler, energy saving 5-20%.
