Water circulation issues during start-up of coal-water slurry gasification
Thread Content
When the gasifier is started, water circulation must be established. How much of the water circulation volume of this system generally accounts for the quenching water flow rate according to the design perspective? ?
If I had to give a measure, I think it would be about half.
Note that the liquid level controlled by the gasifier is different before and after changing the process burner, and ensure the negative pressure of the gasifier before (to prevent high liquid levels and backfires that could injure people). ) Afterwards, you can control and increase the liquid level of the gasifier (generally half is appropriate)
50--80% of the total amount of chilled water.
The feeding during start-up is generally half load, so the quench water should be more than 50%.
