Effect of central oxygen content variation on syngas composition
Thread Content
Regarding the effect of changes in central oxygen content on the composition of syngas, is the impact on H2 the most significant? Haiyou discussion! Looking forward to it. . . .
Suggestion: Conduct an experiment by maintaining a constant oxygen level at the center for 24 hours, and record the amounts/compounds of the process gas as well as the amount of residue. Then change the oxygen ratio at the center and repeat the process to identify the optimal control point. This is a simple task that can be easily carried out by any slurry coal manufacturer
The oxygen content at the center has a significant impact on the gasification furnace. Without central oxygen, the gasification performance is very poor, the gas composition fluctuates greatly, and the methane content increases significantly. Typically, central oxygen accounts for 15%–20% of the total oxygen amount; a level below 7% may affect the gasification performance. The gasification temperature can be balanced by adjusting the central oxygen flow rate. Generally, as the flow rate increases, the temperature at the upper part of the gasification furnace rises; while when the flow rate decreases, the temperature at the bottom of the gasification furnace (the slag outlet) increases.
