When adjusting the oxygen-to-carbon ratio, under what circumstances should oxygen be adjusted? . . . . Under what circumstances should carbon be adjusted? Thank you
Could the original poster be more comprehensive? The meaning expressed in this way doesn’t seem very clear.
When production is insufficient, the adjustment amount is small; when production is excessive, the adjustment amount is large
The oxygen-to-carbon ratio is set automatically, and no significant adjustments are usually made; generally, only the oxygen supply is adjusted, while the coal supply adjusts automatically accordingly
Since it’s the oxygen-to-carbon ratio, it needs to be compared together; you can figure out the ratio on your own.
When adjusting the load in general, oxygen supply is adjusted first, and then the amount of coal is adjusted using a basically fixed oxygen-to-coal ratio; Shell’s oxygen-to-coal ratio is typically kept between 0.7 and 0.9, with little change
1. Load addition principle: add coal first and then oxygen; both manual and automatic modes must comply with this. Oxygen and coal can be quickly alternated. 2. During high-load production, when the oxygen-to-carbon ratio is low, the oxygen level needs to be adjusted. Carbon can be reduced during low-load production. 3. To eliminate the lag in the automatic adjustment of the oxygen-carbon ratio, it is generally done manually; once stability is achieved, the automatic adjustment is activated.
When loading the system, coal (steam) is added first, followed by oxygen； When reducing the load, oxygen should be reduced first, followed by coal (steam), right?
