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

2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Increasing the boiler pressure results in higher average steam temperature in the boiler. This effect allows additional work to be done in phase 2-3 (Fig. 10.3c). However, there is some loss of useful work in phase 3-4 because of necessity to re-heat the steam
