AI Technical Summary
Dust accumulation on the inner surface of the flue pipes of existing boilers leads to a decrease in heat transfer efficiency. Existing cleaning methods are ineffective and may cause secondary pollution.
The system employs a combination of jet and water spray components, along with high-pressure gas and liquid spraying. Dust is efficiently removed from the inner surface of the flue pipe through air and water nozzles. The top block structure pushes out the dust, which is then adsorbed by water spraying, achieving highly efficient dust removal.
It effectively removes dust from the inner surface of the flue, improves heat transfer efficiency, reduces energy consumption, avoids secondary pollution, and does not damage the flue.
