- Given Data:
- Pressure before throttling, P1 = 1.4 MPa
- Pressure after throttling, P2 = 0.1 MPa
- Temperature after throttling, T2 = 110°C
- Calculations:
- From steam tables, at 1.4 MPa and 110°C, h1 = 2783.3 kJ/kg
- At 0.1 MPa, the enthalpy of saturated liquid, hf = 417.5 kJ/kg
- At 0.1 MPa, the enthalpy of saturated vapor, hg = 2676.5 kJ/kg
- Using the throttling calorimeter equation:
- h1 = hf + x * (hg - hf)
- 2783.3 = 417.5 + x * (2676.5 - 417.5)
- x = (2783.3 - 417.5) / (2676.5 - 417.5) = 0.924
- Result:
- The dryness fraction of the steam leaving the boiler is 0.924.
By using the given data and steam tables, we can calculate the dryness fraction of the steam leaving the boiler after passing through the throttling calorimeter. The dryness fraction indicates the quality of the steam, with a value of 1 representing dry saturated steam and 0 representing saturated water. In this case, the dryness fraction is found to be 0.924, indicating that the steam is almost dry saturated steam.
