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 … WebSolved Problem 4.2 - An Open Feedwater Heater added to the Supercritical Steam Power Plant for Athens, Ohio. This Solved Problem is an extension of Solved Problem 4.1 in which we extend the de-aerator by tapping steam from the Low Pressure turbine at 800 kPa and feeding it into the de-aerator at the same pressure, thus converting it into an …
WebProcess 1-2: Expansion of steam through the turbine with constant entropy. Process 2-3: Condensation process through the condenser at constant pressure. Process 3-4: Pressurization of the working fluid by the feed pump I up to the pressure at which working fluid will enter in to the feedwater heater for mixing with the extracted steam. Process ... Webadding either open feedwater heaters and/or closed feedwater heaters, the efficiency of the cycle will increase [2]. This is due to the raise of the mean feedwater temperature at the boiler inlet which is heated by the extraction steam. The study has been done to determine[3] the effect of the number of closed feedwater heaters
