WebThe high pressure feedwater heater is a counter flow, shell and tube heat exchanger that raises the temperature of the feedwater before entering the steam generator. By raising the feedwater temperature, the steam generator is more efficiently sized for its task of converting feedwater to steam and the plant operates at a higher efficiency. WebThis example models a steam turbine system based on the Rankine Cycle. The cycle includes superheating and reheating to prevent condensation at the high-pressure turbine and the low-pressure turbine, respectively. The cycle also has regeneration by passing extracted steam through closed feedwater heaters to warm up the water and improve …
Weband 590 C; one closed feedwater heater is at 3.4 MPa; an open feedwater heater is at 170 kPa; and the condenser pressure is 13 kPa. The adiabatic turbine and pump efficiencies are 85%. The terminal temperature difference in the closed feedwater heater is 3 C and the drain for the closed feedwater heater is trapped to the open feedwater heater ... WebAt the intermediate pressure between the two pumps, the working fluid is heated back to the saturated liquid state in the feedwater heater. By mixing streams 4 and 8 to produce …
WebThe schematic of a steam power plant with one open feedwater heater is shown on the left. In an ideal regenerative Rankine cycle with an open feedwater heater, steam from the boiler (state 5) expands in the turbine to an intermediate pressure (state 6). At this state, some of the steam is extracted and sent to the feedwater heater, while the ... WebAn ideal regenerative Rankine cycle with a closed feedwater heater uses water as the working fluid.
