8.3 The Carnot Cycle as a Two-Phase Power Cycle

A question arises as to whether the Carnot cycle can be practically applied for power generation. The heat absorbed and the heat rejected both take place at constant temperature and pressure within the two-phase region. These can be closely approximated by a boiler for the heat addition process and a condenser for the heat rejection.

Basics of Steam Generation - KTH

A simple power plant cycle. The steam boiler provides steam to a heat consumer, usually to power an engine. In a steam power plant a steam turbine is used for extracting the heat from the steam and turning it into work. The turbine usually drives a generator that turns the work from the turbine into electricity.

steam rankine cycle - an overview | ScienceDirect Topics

In coal-fired boilers, above an operating pressure of 3208 psia (22.1 MPa) in the evaporator part of the boiler, the cycle is termed supercritical. The cycle medium is a single-phase fluid with homogenous properties, and is not necessary to separate steam from water in a drum. Therefore, once-through boilers are used, which do not contain drums.

Rankine cycle - Wikipedia

The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. 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.

Chapter 8

Steam is the working fluid in an ideal Rankine cycle with superheat and reheat. Steam enters the first-stage turbine at 8.0 MPa, 480°C, and expands to 0.7 MPa. It is then reheated to 440°C before entering the second-stage turbine, where it expands to the condenser pressure of 0.008 MPa. The net power output is 100 MW.
