Why does the gasification burner need primary oxygen and secondary oxygen? Is there any technological use for this?
The purpose of passing high-pressure oxygen through the gasification burner is to atomize the coal-water slurry and to pass the secondary oxygen. In order to atomize the coal-water slurry for the second time,
Why does the gasification burner need primary oxygen and secondary oxygen? Is there any technological use for this? What does it mean, it is peripheral oxygen and central oxygen. Tsinghua's two-stage furnace has primary oxygen and secondary oxygen. The primary oxygen is mainly added to the main burner for atomization. The role of the secondary oxygen is secondary combustion, which makes the reaction temperature of the gasifier better, tends to be a constant-temperature reactor, and reduces the wear and erosion of the refractory bricks on the upper cylinder of the gasifier.
Currently, only Tsinghua University’s non-melting-melting two-stage vaporization has primary oxygen, secondary oxygen and two oxygen additions.
