(5) T x = (T b-T c) N + 1 where T x is the temperature rise per heater for maximum efficiency, T b the saturation temperature corresponding to boiler pressure (Pb), T c the saturation temperature corresponding to condenser pressure (Pc), N the number of feed water heaters which in the present cycle is 2 (one OWH and one CHW), T x is the

A back pressure steam cycle works as follows. The boiler p roduces 8 kg/s of steam at 40 bar and 500 oC. This is expanded to 2 bar with an isentr opic efficiency of 0.88. The pum p is supplied w ith feed water at 0.5 bar and 30 oC and delivers it to the boiler at 31 oC and 40 bar. Calculate the net power output of the cycle. (Answer 5.24 M W )

----- ABSTRACT This document presents the findings of an extensive study of the steam electric power generating point source category for the purpose of developing effluent limitations, guidelines, standards of performance for new sources, and pretreatment standards for the industry in compliance with and to implement Sections 30U, 306 and 307 of the Federal Water Pollution Control Act

Mar 19, 2015· Some steam is attracted from the turbine at 40 bar for closed feed water heater and remaining steam is reduned at -30 bar to 600"C. Extracted steam is completely mnderueed in this closed feed water heater and is pumped to 150 bar bvforv mixing with the feed water heater.

c) Compression of wet vapor is difficult and involves large work in case of Carnot cycle when compared to the pumping work of feed water to the boiler in case of a Rankine cycle. 25 Effects of pressure and temperature on Rankine cycle performance: a) Lowering the condenser pressure increases the thermal efficiency of the cycle: The effect of

A steam Rankine cycle operates between the pressure limits of 2500 psia in the boiler and 1 psia in the condenser. The turbine inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 1000 kW of power.

5 - Consider a steam power plant that operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater and one reheater. Steam enters the turbine at ( 15 MPa ) and ( 600 C ) and is condensed in the condenser at a pressure of

File Size: 204KB Steam is the working fluid in a simple, ideal Rankine cycle. Saturated vapor enters the turbine at 8 MPa and saturated liquid exits the condenser at a pressure of 8 kPa. The net power output of the cycle is 100 MW. Determine for the cycle: i. Thermal efficiency. ii. Back …

A back pressure steam cycle works as follows. The boiler produces 8 kg/s of steam at 40 bar and 500oC. This is expanded to 2 bar with an isentropic efficiency of 0.88. The pump is supplied with feed water at 0.5 bar and 30oC and delivers it to the boiler at 31oC and 40 bar. Calculate the net power output of the cycle. (Answer 5.24 MW)
