Reheating of steam in a turbine
WebSteam at 7 is reheated in the reheat section (RH) to a higher temperature at 8 where steam expands further in the intermediate-pressure steam turbine (IPST) to the low pressure at 10. Web7 Steam at 10 MPa, 6008C enters the first-stage turbine of an ideal Rankine cycle with reheat. The steam leaving the reheat section of the steam generator is at 5008C, and the condenser pressure is 6 kPa. If the quality at the exit of the second-stage turbine is 90%, determine the cycle thermal efficiency. We have an Answer from Expert.

Description: The SST-900 is a single-casing steam turbine with up to 250 MW power output, normally providing direct drive of a 3,000 or 3,600 rpm generator. The SST-900 steam turbine series is designed and manufactured to meet the specific demands of ... WebA Rankine-cycle power plant has one stage of reheat. The steam at the turbine inlet is at 500°C and 3 × 10 6 Pa. After expansion to 0.5 × 10 6 Pa, the steam is reheated to 500°C, and expanded in a second turbine to a condenser pressure of 0.007 × 10 6 Pa. The steam leaves the condenser as saturated liquid.
Web4.6 TURBINE MODEL. For a simple non-reheat type turbine, the model is given by a single time constant but reheat turbines have more than one time constant. If a reheat unit has two-stage steam turbines, the dynamic response will be influenced by: The entrained steam between the steam inlet valve and first stage of turbine and. The storage ...
