Deeply engaged in VPSA oxygen generation technology, Lirun Technology has successfully implemented multiple industrial oxygen systems, delivering professional oxygen-enrichment solutions for the steel, non-ferrous metallurgy, cement, glass, and environmental protection industries. Steel Industry: Supported multiple clients with blast furnace oxygen-enrichment systems. By leveraging pre-furnace oxygen mixing technology, operating costs were reduced and oxygen venting was minimized. Non-Ferrous Metallurgy: Completed multiple projects, supplying customized oxygen-enrichment solutions for copper and lead smelting, achieving reductions in overall energy consumption. Glass Industry: Deployed oxygen-enriched combustion systems achieving energy savings and improvement in thermal efficiency. To further support customers, the company provides equipment leasing and professional O&M services, ensuring  stable system operation, design availability of≥99%（This is a design target value; actual operation may be affected by working conditions, maintenance, and other factors）and 24/7 stable oxygen supply.

Core Application Industries

The equipment leasing model is precisely tailored to serve six major oxygen-intensive sectors:

· Glass and fiberglass furnaces

· Non-ferrous metal smelting (including recycled metals)

· Blast furnace oxygen-enriched ironmaking

· Cement kiln optimization

· Waste incineration treatment

Serving a wide range of customers across the industrial oxygen sector.
