How to increase the suction in the riser tube
Thread Content
Our company uses 4.3-meter ramming coke ovens; the ammonia pressure is 0.25 MPA at low pressure and 2.8 MPA at high pressure. There is only one nozzle used, and currently we are employing seven-hole guide vanes, but the suction strength is not ideal, ranging between 500–900 PA. If anyone has any good suggestions or equipment, I’m willing to pay to purchase some for testing. If the results are satisfactory, I will place bulk orders. Thank you in advance
High-pressure ammonia water at 2.8 MPA, with a suction force between 500-900 PA
When high-pressure ammonia water is turned on, a negative pressure, that is, a suction force, is created at the bridge tube, which allows the dust generated during coal loading to be drawn into the rising pipe.
What does that mean? Is the jet force of high-pressure ammonia water insufficient? Can’t the smoke be removed?
Replacing it with a three-line, four-channel nozzle can increase the negative pressure
Could you send a picture so I can take a look? Can a coke oven with a capacity of 4.3 be used?
Do you mean that more smoke is produced when high-pressure ammonia is used during coal loading? You can check what the fan speed is when you load coal The rotation speed can be increased appropriately; if it cannot be increased, you can modify the dust removal duct of the smoke exhaust vehicle to enhance the suction power. In other words, a valve should be added to the dust removal main pipe between the two furnaces.
500-900 is also acceptable; one should not consider only the spraying location, but also make adjustments based on the actual circumstances
How is the operation of your blower’s automatic control system? It’s not necessarily a problem with the nozzle or suction. This is the type of nozzle we use. ,
