How can the water inside the furnace tube be cleaned more effectively?
Thread Content
Dear Teacher shiyue528, may I ask how to better clean the water inside the furnace tubes after the hydraulic test of the heating furnace is completed?
To ensure that the water inside the heating furnace tubes is completely removed, the following steps can be considered: 1. **Drainage**: First, open all the drainage valves in the furnace tube system to allow the water to flow out naturally. Ensure that every part of the system is thoroughly emptied. 2. **Purging**: Use compressed air or nitrogen to purge the pipes, helping to remove any residual water inside them. This step is very effective for completely removing moisture from the pipes. 3. **Heating**: After purging is complete, the pipes can be heated to evaporate any remaining moisture. It is necessary to control the temperature carefully during this step to avoid damaging the pipes. 4. **Check**: Finally, conduct a check to ensure that all parts are dry and there is no residual moisture. A humidity detector can be used to verify the level of dryness inside the pipeline. By following the above steps, moisture within the heating furnace tubes can be effectively removed, ensuring the dryness and safe operation of the system. I hope this information is helpful to you! .
Disconnect the flange at the outlet of the furnace tube and install rupture discs (we used 2 thick asbestos sheets). Once this is done, pressurize the furnace tube with air or nitrogen until the rupture discs are stressed and break; then continue to feed water for 20 seconds before stopping the air supply. After repeating this several times, the moisture level inside the furnace tube will meet the required standards
System drying is required; the nitrogen circulation from the recycle hydrogen compressor is used to remove all moisture from the heating furnace, the pipes of the reaction system, and within the reactor
