CHP system (Exhaust Heat Collector)1. The unique spiral winding structure increases the turbulence effect, and the heat exchange capacity per unit area is 3-7 times that of the traditional heat exchanger.
2. High heat transfer coefficient, high heat exchanger heat transfer efficiency, good heat transfer effect, high heat transfer coefficient up to 14000W/m·k, energy saving effect is remarkable.
3. Small size. With only one-tenth of the traditional tube and shell heat exchangers, it takes up less space and reduces infrastructure and installation and maintenance costs.
4. Using a small clearance design to increase the flow rate, the heat exchanger is not easy to foul, and the use and maintenance costs
are low.
5. Advanced design concept, the length of the heat exchange tube is 3-4 times the height of the cylinder, the material stays longer and the
heat transfer is more fully.
6. Spiral-wound elastic tube bundle design can effectively eliminate pipe vibration and stress due to thermal expansion and contraction deformation.
7. Unique 90 degree connection, heat exchangers all participate in heat exchange,
no dead ends and stagnant areas, reduce fluid resistance.
8. Counter-current heat transfer, asymmetric flow design, in the vapor-liquid heat transfer field has other advantages that can not be compared with heat exchangers.
Automatic Paralleling and Gridconnect Control SystemThis system can connect generator sets in parallel or connect the generator set to the grid automatically.
