Product Description
Industrial boilers, as core energy supply equipment in
manufacturing, power generation, and heating industries, face
urgent demands for efficiency improvement and emission reduction.
Oxygen-enriched combustion—boosting boiler thermal efficiency by
increasing oxygen concentration in combustion air—relies heavily on
stable, cost-effective oxygen supply. The vpsa oxygen generator (Vacuum Pressure Swing Adsorption Oxygen Generator), a
high-performance Industrial Oxygen Generator, operates on pressure swing adsorption for oxygen production technology. It uses high-efficiency molecular sieves to physically
separate oxygen from ambient air, delivering 93% pure oxygen with
no chemical additives. Compared with cryogenic oxygen production,
it features fast start-up, flexible load adjustment, and low energy
consumption; compared with conventional psa oxygen generator, it offers larger output and better adaptability to continuous
boiler operation. This 90Nm³/h model, customized for industrial
boiler scenarios, cuts fuel consumption by 15%-20% and reduces NOₓ
emissions by 30%, becoming a key equipment for green boiler
transformation.

Boiler oxygen-enriched combustion has strict requirements for
oxygen supply: large continuous output, stable purity, and low
energy consumption—all fulfilled by vpsa oxygen generator:
- Efficiency boost vs. air combustion: Traditional air combustion uses 21% oxygen, with nitrogen
absorbing 70% of heat and increasing flue gas emissions. 93% pure
oxygen reduces nitrogen content in combustion air, raising boiler
thermal efficiency by 8%-12% (e.g., a 10t/h gas-fired boiler saves
150m³ of natural gas daily).
- Stability vs. liquid oxygen: Liquid oxygen requires large storage tanks and has high
transportation costs; its supply is easily affected by weather and
logistics. The VPSA generator produces oxygen 24/7, with a 2Nm³
buffer tank ensuring stable supply during boiler load fluctuations.
- Cost vs. psa oxygen generator: psa oxygen generator (pressure swing adsorption) has higher energy consumption
(≥0.85kWh/Nm³ O₂) and smaller output (≤50Nm³/h), making it
unsuitable for 10t/h+ boilers. The VPSA model’s vacuum regeneration
technology cuts energy use by 30%, matching large boiler demands.
Both vpsa oxygen generator and psa oxygen generator belong to pressure swing adsorption oxygen plant technology, but their regeneration methods create distinct boiler
adaptability:
- PSA working principle: Relies on atmospheric pressure regeneration—adsorbs nitrogen at
high pressure (0.7-0.9MPa) and desorbs at atmospheric pressure. It
has a simple structure but requires high compression energy,
leading to higher power consumption. Suitable for small boilers
(≤5t/h) with low oxygen demand.
- VPSA working principle: Uses vacuum regeneration—adsorbs at low pressure (0.3-0.5MPa) and
desorbs at negative pressure (-0.08MPa). The optimized regeneration
process reduces compression energy use, lowering unit energy
consumption to ≤0.61kWh/Nm³ O₂. Its dual-tower alternating design
ensures continuous output, critical for 24/7 boiler operation.
- Boiler-specific optimization: The VPSA generator adds a flue gas heat recovery module, using
waste heat from boiler flue gas to preheat intake air, further
reducing energy consumption by 5%-8%.
National environmental protection policies (e.g., "Dual Carbon"
goals, boiler emission standards) make VPSA oxygen generators a
policy-compliant choice:
- Emission reduction: 93% purity oxygen reduces boiler flue gas volume by 30%, cutting
NOₓ emissions by 30% and CO by 40%—helping enterprises meet strict
emission limits (GB 13271-2014).
- Energy-saving subsidies: Many regions offer 10%-15% equipment subsidies for enterprises
adopting energy-saving oxygen-enriched combustion technology,
reducing initial investment burdens.
- Carbon credits: Reduced fuel consumption lowers carbon emissions, allowing
enterprises to trade carbon credits and gain additional revenue.
The 90Nm³/h 93% purity vpsa oxygen generator has become a core equipment for industrial boiler green
transformation, leveraging advanced pressure swing adsorption oxygen plant technology to balance efficiency, cost, and emission reduction.
Compared with psa oxygen generator and traditional oxygen supply methods, it delivers larger output,
lower energy consumption, and more stable performance—perfectly
matching the continuous, large-scale oxygen demand of industrial
boilers. Its ability to cut fuel costs by 15%-20% and reduce NOₓ
emissions by 30% not only improves enterprise profitability but
also helps comply with environmental policies. For enterprises
operating 10t/h+ industrial boilers, investing in this VPSA oxygen
generator is a cost-effective, future-oriented decision that
supports sustainable development while enhancing core
competitiveness. As boiler emission standards tighten, VPSA Oxygen System will play an increasingly critical role in the industrial
energy-saving revolution.
