12A steam generating unit produces steam at the rate of 10 kg/s at 5 MPa, 450°C, which is continuously blown down at 0.25 kg/s. Feedwater enters the feed of the steam boiler. Steam Properties: At 5 MPa, 450°C, h=33162 kJ/kg-K. At 5 MPa, 100°C, h=42272 kJ/kg-K. At 5 MPa, h=1154.23 kJ/kg-K. h=2794.30 kJ/kg-K. 69.30°C. 61.26. 63.39. 4.66.21.
13A steam generating unit receives feedwater at 5 MPa, 200°C, and delivers steam at 4.5 MPa, 320°C, at a rate of 30000 kJ per hour. The main turbine has a steam rate of 65 kg/kW-hr of generator output. An induced-draft fan with 25 kW, an induced-draft fan with 40 kW, and a soot blower with 3300 kg/day are used. With a higher heating value of 40,000 kJ/kg, the fuel consumed is at a rate of 1890 kJ per hour for the steam generator net efficiency. Steam Properties: At 4.5 MPa, 320°C, h=3000.6 kJ/kg-K and at 5.0 MPa, 200°C, h=85.9 1/g-K. 86.3. 83.6. 81.24. 82.41.
