How is the evaporation area of a triple-effect evaporator determined?
Thread Content
Vertical shell-and-tube； Shell side: saturated steam at 0.4 MPa enters, condensed water at 90°C exits ； Piping, 25°C, 5 t/h water inflow ； The required evaporation rate is 3 t/h. If the heating area of each heater stage is the same, what should it be? What is the simple calculation process? Also, what is the consumption of primary steam?
Is there anyone experienced here? Are the tube side and shell side calculations done in two separate stages each?
