Questions regarding the on-line analysis of syngas composition

The gasification furnace has a CO content of 43%, with a CO2 content of over 20%. The furnace is cooled down until a large amount of fine slag appears, indicating that the furnace temperature is low; yet the effective CO content remains high. Additionally, the CO content fluctuates quite significantly at times, with short-term variations of 1% to 2%. What’s the situation among those using this furnace? How to solve it? Thank you!
79% of the content within the shelf life is also quite acceptable. Does the poster have a coal water slurry furnace? What was the coal slurry concentration at that time?
If the CO content in the water-coal slurry gasifier is already high, and if the slag outlet is not blocked, reducing the furnace temperature appropriately will increase the hydrogen content, thereby raising the content of useful gases as well.
