Recycling fluoroplasticsDisadvantages of heat exchanger flue gas waste heat

1. The pressure resistance of the recycled fluorine plastic heat exchanger is low, which is not enough to withstand the pressure of the condensate after the condensate pump. Therefore, condensate as a heat exchanger water, we must take into account the impact of load changes on the system pressure. Otherwise, the aftermath will be endless.

2. The fluorine plastic pipe works at the acid dew point temperature for a long time, and the flue gas side often has acid condensation. The acid will penetrate into the water system for a long time, which will reduce the PH value of the circulating water. Corroded pipes and blocked pipes. Serious conditions will affect the water oh.

3. Fluoroplastic tube heat exchanger can not work for a long time in the high ash area before ESP, and the wear resistance of large particle dust with edges and corners is insufficient.

4、Recycling fluoroplasticsThe heat exchanger should not work in the high temperature area (above 200 ℃ flue gas environment) for a long time with closed circulation pressure.

5. The wall thickness of fluorine plastic heat exchange tube is relatively thin and the tube is relatively soft, so it is easy to cause man-made damage in the process of storage, transportation, hoisting, starting, shutdown and maintenance.
