基于射流强化的冷凝换热器
By using jet-enhanced design and jet flue gas and guide plate structure, the condensate film and boundary layer are disrupted, solving the problem of heat exchanger capacity decline after long-term operation. This achieves efficient condensate shedding and stable discharge, enhancing the durability of the condensate heat exchanger.

AI Technical Summary
Technical Problem
Existing condensing heat exchangers experience a decline in heat exchange capacity after prolonged operation, and existing enhancement methods are costly and have poor durability.
Method used
The system employs high-speed jet flue gas injection through jet holes to scour the surface of the water coil. Combined with the design of guide plates and sloped surfaces, this disrupts the condensate film and non-condensable gas boundary layer, enhancing the condensation heat exchange capacity. The condensate is then collected by gravity.
Benefits of technology
It enhances the heat exchange capacity of the condenser heat exchanger, reduces thermal resistance, achieves efficient condensate removal and stable discharge, and improves the system's durability.
