Condenser Calculation, Using Thermo Utilities v2.0, MS Excel Add-ins Condenser Calculation, Using Thermo Utilities, MS Excel Add-ins A surface condenser is required to deal with 15 000 kg/h wet steam. Wet steam temperature is 37 C and enters the condenser with 0.95 quality (dryness fraction is 0.95). The water used for cooling has the following data: - Inlet pressure 1.20 bar, inlet temperature 7 C - Outlet pressure 1.013 bar, outlet temperature 22 C Calculate the flow rate of cooling water and tube surface of the condenser.
Selection of software according to 'Condenser design calculation excel' topic. You need to calculate the heat load on the condenser, select the cooling medium for the condenser, and calculate the flow rate of the cooling medium. With the heat load, you calculate the required heat transfer area for the condenser. All these calculations should already have been made in the submitted workbook.
Assume that the cooling water velocity through tubes is 1.5 m/s Inputs Units Wet steam inlet temperature 37 C Steam quality 0,95. Cooling water inlet temperature 7 C Cooling water inlet pressure 1,2 bar Cooling water outlet temperature 22 C Cooling water outlet pressure 1,013 bar Steam mass flow 15000 kg/h Cooling water speed 1,5 m/s Outputs. Wet steam pressure 0,06274 bar Enthalpy of steam at inlet 2448,28 kJ/kg Entropy of condense 154,92 kJ/kg Rejected heat/hour 34400441,72 kJ/h Rejected heat/second 9555,68 kJ/s = kW Enthalpy of water at inlet 29,53 kJ/kg Enthalpy of water at outlet 92,31 kJ/kg Water mass flow 547885,14 kg/h The overall heat transfer coefficient can be calculated according to BEAMA or HEI standards.
