2000Nm³/h 92% Purity VPSA Oxygen Generator for Biomass Power Generation
Product Overview
The VPSA Oxygen System (Vacuum Pressure Swing Adsorption Oxygen Generator) is a large-scale industrial oxygen supply equipment based on vacuum pressure swing adsorption technology. It separates air in a vacuum environment through high-efficiency molecular sieves, featuring core advantages of large output, low energy consumption, stable purity, and strong continuous operation capability.
As a flagship model of vacuum swing adsorption oxygen generator, the 2000Nm³/h flow rate and 92% purity can accurately match the oxygen-enriched combustion needs of biomass power generation boilers. It can increase combustion efficiency by more than 30% and reduce carbon emissions by 25%, serving as a core equipment for biomass power generation projects to achieve energy conservation and carbon reduction.

Technical Adaptability and Operational Advantages
The high-temperature, high-humidity, and dusty environment of biomass power generation boilers imposes strict requirements on oxygen production equipment. The VPSA Oxygen Generator achieves stable adaptation through three technical optimizations:
- Adopts temperature-resistant lithium-based molecular sieves, which can withstand the ambient temperature of 60-80℃ around the boiler, with an adsorption performance attenuation rate of ≤5% per year.
- Enhances the pretreatment system, purifying intake air through three-stage filtration (dust removal, dehumidification, tar removal) to avoid contamination of molecular sieves by impurities in biomass flue gas.
- Employs vacuum desorption technology, reducing energy consumption by 20% compared with traditional PSA. The unit oxygen production energy consumption is only 0.35kWh/Nm³, saving more than 500,000 RMB in electricity fees annually based on 8000 hours of operation.
The Vacuum Pressure Swing Adsorption Oxygen Systems technology supports real-time linkage with the boiler's DCS system, automatically adjusting oxygen flow rate according to furnace temperature and steam pressure to achieve "on-demand oxygen supply". This intelligent adjustment capability improves the comprehensive energy efficiency of the equipment by more than 15% compared with traditional oxygen generators.
Installation and Maintenance Guidelines
The installation of the VPSA Oxygen Generator should be planned synchronously with the biomass power generation project. The site selection must meet three requirements:
- Be close to the boiler workshop (pipeline distance ≤50 meters) to reduce oxygen transportation loss
- Be located at a higher elevation than the boiler to avoid rainwater backflow
- Reserve a maintenance channel of ≥3 meters to facilitate module inspection and repair
For maintenance, a "three-level maintenance" system should be established:
- Daily maintenance (daily): Check filter cleanliness and equipment pressure
- Regular maintenance (monthly): Test oxygen purity and molecular sieve performance
- In-depth maintenance (annual): Replace aging valves and seals, and conduct air tightness testing on adsorption towers
With its 2000Nm³/h super-large flow rate and 92% stable purity, the VPSA Oxygen Generator has become an efficient combustion-supporting equipment for biomass power generation. Its VPSA Oxygen System technology can not only improve power generation efficiency but also help meet environmental standards.
