Question

A steam turbine plant is equipped with a single regenerative feedwater.Steam at an initial pressure of 16 bar with an enthalpy of 3000 kj/kg entersthe turbine. It is extracted at 2 bar where its enthalpy is 2600 kj/kg. Exhauststeam comes out at a pressure of 0.05 bar and enthalpy 2115 kj/kg. If thethermal efficiency of the cycle is 34%, the condenser duty with regenerationis(the enthalpy of saturated liquid at 2 bar and at 0.05 bar is 505 kj/kg and140 kj/kg

Answer 1

Explanation:

• A steam turbine plant is equipped with a single regenerative feedwater.Steam at an initial pressure of 16 bar with an enthalpy of 3000 kj/kg entersthe turbine.
• It is extracted at 2 bar where its enthalpy is 2600 kj/kg. Exhauststeam comes out at a pressure of 0.05 bar and enthalpy 2115 kj/kg.
• If thethermal efficiency of the cycle is 34%, the condenser duty with regenerationis(the enthalpy of saturated liquid at 2 bar and at 0.05 bar is 505 kj/kg and140 kj/kg....
