I need an expert to help calculate the heat transfer flow rate
Thread Content
I need to reduce the water vapor from 140 degrees to 30 degrees over a period of 20 minutes. The heat exchange type is shell-and-tube. My cooling water temperature is 7°; what should be the flow rate of the cooling water? How many kg of pressure is needed?
Parameters of the heat exchanger: heat load, steam flow rate, enthalpy value
Such operating conditions can be fully handled using plate heat exchangers with higher heat transfer efficiency
Steam flow rate: 500 kg/h; no other parameters specified
Steam at 140 degrees is within the applicable range for plate exchangers. Plate exchangers are similar to shell and tube exchangers; the only differences lie in the requirements regarding temperature and pressure
When you measure heat at 30 degrees, does it involve converting water vapor into condensed water at 30 degrees, or remains it as water vapor? Is this done to eliminate superheated steam or to cause the steam to condense?
