Atomization effect of the burner

The flow rate of the water-coal slurry gasification burner is sufficient, but the oxygen pressure difference is greater than 0.2 Mpa compared to the pressure in the gasification furnace; it is also lower than the pressure of the coal slurry, which is 0.3 Mpa higher than the pressure in the gasification furnace. Although the burner relies on flow velocity for atomization, the flow velocity here is sufficient while the pressure difference is low.
Generally, the pressure for coal slurry testing is measured in the middle of the floor, and there is also a pressure display at the furnace head; one can check what the difference is between this pressure and the pressure in the gasification furnace. The oxygen pressure in Texaco’s gasification process is low, and it is not possible to ensure the atomization of the coal slurry.
”Oxygen pressure difference < vaporizer pressure by 0.2 Mpa. What does this mean?
It is that the pressure of the oxygen burner is lower than that of the gasification furnace.
It’s inside now; otherwise, how can it burn?
It’s not easy to get low-pressure energy into high-pressure areas! Know how to do something, right?
If the pressure is indeed high, both the coal slurry and syngas will flow into the oxygen pipe. . .
