Sample Calculation

STEAM conditions 250 lb/in2 (1724 kPa) gage inlet, 575°F (302°C) inlet, and 50 lb/in2 (345 kPa) gage exhaust.

design conditions turbine to develop 500 hp (373 kW) at 4000 rpm.

1. Theoretical steam rate = 26.07 lb/kWh (11.82 kg/kWh)

2. Base steam rate for 28-in (71.12-cm) wheel (Figure 7) = 36 lb/hp • h (22 kg/kWh)

3. Power loss for 28-in (71.12-cm) wheel (Figure 8) = 55 hp (41 kW)

4. Temperature of dry and saturated inlet steam (Table 1) = 406°F (208°C)

5. Superheat (Table 1) = 575 - 406 = 169A°F (302 - 208 = 94A°C)

6. Superheat corrections factor (Figure 9) = 1052

36 500 + 55 In USCS units -t^t X 500+ 55 = 38.0 lb/hp-h

Renewable Energy Eco Friendly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
