A unique arrangement of the superheater is discussed whereby part of the steam heat load is shifted to the reheat gas turbine to obtain a mini­. Utility boilers are operated under sliding pressure mode and hence Reheat steam temperature control by spray is a common practice especially for once-through boilers. This paper deals with the benefits and losses of using spray for Reheat steam temperature control in lieu of other control mechanisms. If the plant incorporates reheat and.

The function of injector used in small capacity boilers is to (a) create vacuum (b) inject.   GGas Turbine Cycle with Reheat A common method of increasing the mean temperature of heat reception is to reheat the gas after it has expanded in a part of the gas turbine. By doing so the mean temperature of heat rejection is also increased, resu.

    Transformers outside the plant building step up this voltage to , volts so that it can be transmitted efficiently over a long distance. The high pressure (HP) turbine drives one shaft together with low pressure (LP) turbines A and B, and the intermediate pressure (Reheat) turbine drives the second shaft together with LP turbines C and D. 3.

Figure depicts a steam-cooled gas turbine combined cycle (Smith, a) with a triple pressure reheat steam cycle (most gas turbines are air cooled, however, the cooling air being provided by the gas turbine compressor).

Ambient air is drawn into the gas turbine air compressor via a filter to remove air-borne particulates, especially those that are larger than 10 microns. The STF-D Series is designed for main inlet conditions up to °C (°F) and bar ( psi) and reheat temperatures up to °C (°F).

HP turbines can be equipped with a second main steam injection system by means of integrated overload valves. This method provides additional load reserve in cases of sudden steps in power demand.

Reheat turbines are also used almost exclusively in thermal power plants. All turbines, that have high-pressure turbine and low-pressure turbines use a steam reheat between these stages.

Reheat steam turbines are efficient, flexible and reliable machines based on a broad design platform, capable of satisfying a wide range of steam cycles, site conditions and operating modes for both 50 and 60 Hz applications.

For higher ratings, the design concept is based on separate high pressure and intermediate pressure sections with one. The advances of reheat cycles proven at Philo Station and then again at the Twin Branch Station provided the promise of efficiency improvements to come.

Reheat not only effectively reduced the penalty of the latent heat of vaporization in steam discharged from the low-pressure end of the turbine cycle, but it also improved the quality of the steam at the low-pressure end of the turbines by.

Rankine cycle with reheat and superheat the low-pressure stage. Reheat turbines are also used almost exclusively in thermal power plants.

All turbines, that have high-pressure turbine and low-pressure turbines use a steam reheat between these stages. GE’s STF-A non-reheat platform. GE’s STF-A non-reheat platform provides cogeneration of power steam in an flexible and compact design for either 50 or 60 Hz applications, from MW to MW.

Our fully modular concept combines HP, IP, and LP sections to. The design of a reheat turbine emphasizes today's requirements that all new designs provide low fuel consumption to the operators.

The capital cost for these plants can be justified and the present designs of both reheat turbines and boilers strongly indicate that risk and maintenance costs are not prohibitive. Reheating in gas turbine is done in order to increase the efficiency of the turbine. For this gas turbine is divided into number of stages and they are classified as high pressure turbine and low pressure turbine.

At each stage power is produce based on the temperature and pressure of the gas. In this Steam Turbines Books section you will find Handbooks Training Material and slides related to Steam turbine auxiliaries, design and operation and maintenance.

In turbine: Reheat and nonreheat turbines. If high-pressure, high-temperature steam is partially expanded through a turbine, the efficiency can be increased by returning the steam to the steam generator and reheating it to approximately its original temperature before feeding it back to the turbine.

A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in.

Technology Characterization – Steam Turbines. Introduction. Steam turbines are one of the most versatile and oldest prime mover technologies still in general production used to drive a generator or mechanical machinery.

The first steam turbine used. @article{osti_, title = {Turbine control system for sliding or constant pressure boilers}, author = {Callan, P C and Eggenberger, M A}, abstractNote = {An automatic control system enabling comprehensive operation of a reheat steam turbine with sliding or constant pressure boilers is described.

The control system includes an HP control valve for regulating steam flow to the high-pressure. I was a TA for my thermodynamics professor so I’ll take a crack at it. A reheater increases the efficiency of your system.

Basically you convert more of the energy being used to create the steam into actual output from your turbine.
