Example Problem - Rankine Cycle (3) - Open Feedwater Heater

WebThe effect of the location of the open feedwater heater on the thermal efficiency of the non-ideal cycle of a steam power plant utilizing the Rankine cycle was investigated. Then, the best location was identified. Also, the addition of the open feedwater heater to the cycle was analyzed in terms of the cost and environmental impact. WebOpen Feedwater Heaters The ideal regenerative Rankine cycle with an open feedwater heater. An open (or direct-contact) feedwater heater is basically a mixing chamber, where the steam extracted from the turbine mixes with the feedwater exiting the pump. Ideally, the mixture leaves the heater as a saturated liquid at the heater pressure. lithium ion beard trimmer
