From the gasification principle already know, the oxygen in the air first and then rising carbon dioxide generated coke; coke and reaction of carbon monoxide, after escaping from the material layer become a gas furnace.

The level of carbon monoxide is decided on oxidation reaction is complete, whether they can produce enough carbon dioxide; the two is to decide whether the reduction of carbon dioxide completely, otherwise it can not change more for carbon monoxide; three is carbon monoxide two combustion, combustion heating furnace should be carried out in the user, to avoid the occurrence of furnace. If the material layer is provided with a wind tunnel, and the direct oxygen furnace surface generated by the oxidation reaction of carbon monoxide, carbon dioxide and combustion, reciprocating prove futile.

So the only stable material layer, the hierarchy, in order to make the oxidation reduction reaction can be fully carried out, in order to get a higher carbon monoxide. On the contrary, in the cold, hot running, running, running is furious, Water Leakage abnormal furnace condition, the carbon monoxide content decreases.

The carbon monoxide content cannot limit the pursuit, such as the pursuit of 31 - 32%, which is not reasonable, because only in the thick material layer, can generate lower saturation temperature conditions, but the long term will inevitably lead to the deterioration of furnace condition.
