1. The plate heat exchanger selects control parameters for heat exchanger material, working pressure, design temperature, etc.
2. Choose heat exchanger, should try to make heat transfer coefficient little side get bigger velocity, and try to make two fluid heat transfer surface on either side of the heat transfer coefficient equal or similar, enhance heat transfer coefficient. The heat exchanger heating the fluid temperature should be under pressure of heat exchanger exports than saturated low temperature, and should be less than 10 ℃ secondary pump water used the working temperature.
3. Contains silt dirt fluid appropriate after filtered into heat exchanger.
4. Choose plate heat exchanger, the outlet temperature smaller side fluid velocity shoulds not be too big, should meet the requirements of pressure drop.
5. For large flow allows pressure drop small situation should choose small resistance of plate type, conversely, choose resistance big plate type.
6. According to the fluid pressure and temperature condition choose removable type or welding type.
7. Unfavorable choose veneer area is too small, lest the plate, plate excessive number of plates between velocity slants small, reduce heat transfer coefficient.
8. The heat transfer medium plate heat exchanger is unfavorable for the steam.
