Regenerative Cycle,Closed Feedwater Heater 2

Regenerative feedwater heating also can be accomplished with closed feedwaterheaters. Closed heaters are shell-and-tube-type recuperators in which the feedwatertemperatureincreases as the extracted steam condenses on the outside of the tubescarrying the feedwater.

Regenerative Cycle,Open Feedwater Heater 2

Open feedwater heater is a direct contact-type heat exchanger in which streams at different temperatures mixto form a stream at an intermediate temperature.

Regenerative Cycle, Introduction

Another commonly used method for increasing the thermal efficiency of vaporpowerplants is regenerative feedwater heating, or simply regeneration.

Vapor Power Systems, Reheat Cycle

The reheat cycle increases the turbine work and consequently the net work of the cycle. This is accomplished not by changing the compressor work or the turbine inlet temperature but instead by dividing the turbine expansion into two or more parts with constant pressure heating before each expansion.

Increase Rankine Cycle Efficiency, Reheat Cycle

The Rankine cycle is a model used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.
