Burner pressure difference
Thread Content
What method is usually used to adjust the burner pressure difference when it fluctuates? Sometimes it gets better gradually without adjustment. Please analyze it.
The problem of burner pressure fluctuation is a problem worthy of attention in Texaco's pressurized coal-water slurry gasification. As for the situation you mentioned (it will gradually get better without adjustment), the general reason is:: 1. The coal slurry pump itself. A. The outlet pressure fluctuates ； B. The flow measured by the pump is unstable ； 2. Cause of burner. A. The coal slurry channel is blocked by large particles ； B. Oxygen influence (especially central oxygen) 3. The most common reason is the wear of the burner head annular gap, which usually occurs in the later stages of operation. Replace the burner. You can adjust the speed of the coal slurry pump appropriately to change the operating status.
