Negative pressure control method for primary and secondary flash in water-coal slurry
Thread Content
The vacuum flash process for water-coal slurry generally consists of an upper tower and a lower tower, with first and second stages; what are the methods for adjusting the negative pressure?
There’s only one method: a vacuum pump. However, when the negative pressure is not sufficient, it’s necessary to determine what the cause is Missed it? Is steam extraction causing the problem? The water cooler is not performing well – can’t the flash vapor be cooled down?
Adjustments are needed when reversing the system; I’m just asking about the technique. Thank you
