Gasification reaction in water-coal slurry gasifier
Thread Content
For water-coal slurry gasifiers, the reverse transformation reaction CO2 + H2 → CO + H2O. It has always been believed that the secondary reactions within the gasifier are primarily those involving C and H2O. However, many people say that in the secondary reaction zone, the reverse transformation reaction also plays a significant role and is quite important. What do you all think?
In the high-temperature range. If water and syngas are not properly mixed, check whether there is more CO or more H2 in the syngas
H2O is the main source of H2 in the vaporization furnace; H2 accounts for a large proportion in the syngas, and the resulting syngas requires further conversion reactions as needed
Considering the length of the gasifier and the residence time of the coal slurry, these should have been taken into account during the design of the gasifier; it’s possible to check the original design documents to see
