Open feedwater heater example

WebAn ideal regenerative Rankine cycle with a closed feedwater heater uses water as the working fluid. The turbine inlet is operated at 500 psia and 600°F and t... 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 ...

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 … WebFeedwater heaters can also be "open" or "closed" heat exchangers. An open heat exchanger is one in which extracted steam is allowed to mix with the feedwater. This kind of heater will normally require a feed pump at both the feed inlet and outlet since the pressure in the heater is between the boiler pressure and the condenser pressure. disintegration apparatus mesh size https://ssfisk.com
