1. Increasing flame temperature: High oxygen purity can effectively increase the theoretical combustion temperature of pulverized coal particles. Simulation results and actual measurements have proved that oxygen-enriched combustion of pulverized coal in cement kilns can significantly increase the flame temperature and overall temperature. 2. Accelerating the combustion rate: Oxygen enrichment can effectively reduce the time…

The VPSA oxygen system mainly includes blowers, vacuum pumps, switching valves, adsorbers and oxygen buffer tanks. (1) Blower: The blower is equipped with a pipe at the entrance to collect the air and continuously provide a certain pressure to create conditions for oxygen production. The blower provides air for the whole oxygen system. According to…

Recently, the first high-grade nickel matte production line of a smelter in Indonesia was officially put into operation. After drying in the drying kiln, roasting in the rotary kiln and smelting in the oxygen-enriched side-blown furnace, high-grade nickel was successfully produced. This marks the world's first successful industrial application of oxygen-enriched side-blown furnace (OESBF) smelting…

In the past 20 years, China's economy has been developing steadily and rapidly. The continuous upgrading and innovation of production processes of iron and steel, non-ferrous metallurgy, chemical industry, furnace, environmental protection and other industries boosted the demand for oxygen, thus promoting the development of oxygen production technologies such as cryogenic air separation process, VPSA…

In early 2020, the Indonesian government announced the ban on nickel ore exports in order to attract foreign investors to open nickel smelters and downstream industries in its territory, of which China is an important contributor. In 2021, the government continued to implement the relevant injunction to ban the export of processed products with nickel…

In June 2022, the VPSA oxygen equipment (7250Nm3/h, 90%) established by PKU Pioneer in Hunan Province was put into operation successfully, providing economical and stable oxygen for oxygen-enriched lead slag smelting section in solid waste treatment process to promote efficient recycling of valuable metals and help the user improve its overall economic benefits. As a…

On July 6th, 2022, the Engineering Department of PKU Pioneer received a Letter of Commendation from a copper smelting customer who fully affirmed the outstanding performance of PKU Pioneer’s technical team in the construction of the VPSA oxygen system project in the letter. Our technical team is highly praised for emphasizing efficiency and surmounting obstacles…

In August 2022, a VPSA oxygen generation equipment (1850Nm3/h, 90%) built by PKU Pioneer for new energy sector was successfully put into operation. Qualified oxygen was generated within 1 hour after the initial start-up with all the indexes meeting the customer's requirements. Upon the delivery of the project, PKU Pioneer's technical team was presented a…

On July 28, 2022, PKU Pioneer attended the 2022 Annual Academic Conference of the Glass Fiber Branch of China Silicate Society and discussed in depth with more than 400upstream and downstreamrepresentatives from the glass fiber & composites industry on the development trend, technical research, and innovative applications of the glass fiber industry in the context…

Bahlil Lahadalia, Indonesia's Minister of Investment, recently stated that Indonesia's foreign direct investment (FDI) grew rapidly in the Q1 of this year, reaching 31.8%, while in the second quarter, it further rose 39.7% annually to 163.2 trillion rupiah ($10.89 billion), which is the highest rate since Indonesia calculate its foreign investment attracted on a quarterly…

The uniformity of air distribution in the adsorption tower has a great influence on the oxygen plant performance, making the design of the air distributor critical. The uneven air distribution will inevitably lead to high airflow velocity in some parts and lower in others. In places with higher velocity, the airflow is larger and the…

In recent years, the air blast of large blast furnaces generally requires oxygen enrichment, and the oxygen added to the air blast must be maintained at the required value for production. The oxygen enrichment can be expressed by oxygen enrichment amount or oxygen enrichment rate which means the oxygen content in the blast and the…
