The oxygen-enriched membrane utilizes the feature that oxygen (O2) has a faster permeation rate in the membrane compared to nitrogen (N2). This functionality allows the membrane to selectively concentrate and enrich oxygen on the downstream side, obtaining a stream of gas with a higher oxygen concentration, known as oxygen-enriched gas.
The oxygen permeation rate through the oxygen enrichment membrane is approximately twice that of nitrogen.
Using air with an oxygen content of 21% as the feed gas, passing it through the oxygen enrichment membrane yields oxygen-enriched gas with a concentration of 26-30%.
| Type | Oxygen Concentration Range | Oxygen Flow Range | Economic Comparison |
| Spiral Membrane Unit | 28-31% | 0.04-50,000 Nm3/h | Compared to cryogenic and (V)PSA methods at an oxygen concentration of around 30% and a scale smaller than 50,000 Nm3/h, the membrane method incurs only about 66% to 98% of the investment, maintenance, and operational costs. |
| Plate Membrane Unit | 28-31% | 0.04-50,000 Nm3/h | Compared to cryogenic and (V)PSA methods at an oxygen concentration of around 30% and a scale smaller than 50,000 Nm3/h, the membrane method incurs only about 66% to 98% of the investment, maintenance, and operational costs. |
| Hollow Fiber Membrane Unit | 30-45% | 0.04-50,000 Nm3/h | Compared to cryogenic and (V)PSA methods at an oxygen concentration of around 30% and a scale smaller than 50,000 Nm3/h, the membrane method incurs only about 66% to 98% of the investment, maintenance, and operational costs. |

This describes the process of oxygen enrichment in combustion using membrane technology.
1). Utilizes specialized oxygen-enriched nozzles, "local oxygen enrichment," "gradient combustion," and "symmetrical combustion" along with other advanced patented technologies.
2). Increases flame temperature and luminosity, significantly enhancing radiant heat.
3). Lowers the combustion ignition point, accelerates combustion speed, promotes safe combustion, thus effectively addressing pollution.
4). Reduces post-combustion exhaust and dust emissions.
5). Lowers fuel activation energy, making combustion easier.
6). Increases heat utilization efficiency, resulting in noticeable energy savings.
7). Reduces excess air coefficient, achieving energy conservation.
8). For glass furnaces, can save energy by 3-35%, increase production by 3-15%, and improve product quality.
9). For boilers and heating furnaces, generally achieves energy savings of 3-30%, with a significant decrease in harmful smoke and dust.
10). Additionally, provides more stable furnace conditions, reduces environmental pollution, extends furnace life, and offers significant overall benefits.
