When the Texaco gasifier is operated at low load, is the oxycoal higher or lower than at full load?
What impact will long-term low-load operation of Texaco gasifier have on the gasifier?
Personal understanding without actual proof: At the same operating temperature, the heat dissipated through the gasifier wall is always basically constant regardless of the load. High load will inevitably generate higher heat to maintain the temperature of the gasifier. ； The opposite is true for low loads. Then under high load, the oxygen-to-coal ratio should be lower than under low load condition.
Long-term operation at low load will affect the rise of the dome temperature, and on the other hand will affect the atomization effect of the burner. Generally, the allowable production load fluctuation range of the burner is 70-100 percent. The oxygen-coal ratio will basically not change much whether the load is reduced or loaded. The oxygen-coal ratio is a set value, and the system will adjust the corresponding amount by adjusting the amount of oxygen or coal slurry. If there is something wrong, please point it out.
It affects the rise of the vault temperature, affects the atomization effect of the burner, and has an erosion effect on the furnace bricks! ! To maintain the same operating temperature and other conditions remain unchanged, the oxygen-to-coal ratio needs to be adjusted! ! !
Agree with the 3rd floor statement: At high load, the oxygen-to-coal ratio should be lower than at low load. The rules of Texaco gasification and Shell gasification are consistent.
Low-load operation affects the atomization effect of the burner, and low-load operation of oxygen coal is higher than that of high-load operation.
