      half of the double flow low pressure case, the thrust bearing pedestal, the high pressure case, and the front pedestal are free to expand or grow toward the governor end of the machine. The generator half of the double flow low pressure section case is free to move toward the generator. Due to the location of the thrust Figure 3.   Condensing turbine is selected when the steam demand for the process drivers is greater than the low-pressure process steam requirements. It is also selected when no high pressure steam is available. Back pressure turbine is selected when process steam demands are greater than the steam required for process drives such as large compressors.

      Low-load operation has recirculation of low-pressure (LP) steam flows at the exit of the LP section of the steam turbine. This can result in trailing . 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 .

    All steam turbines can be classified into two categories; extraction (condensing) steam turbine and non-condensing steam turbine also known as back pressure steam turbines. Both of these steam turbine types have their own operating schemes and ben. Steam turbines have historically been the prime source of power for electric power generation. Turbines come in a variety of types with regard to inlet and exhaust steam conditions, casing and shaft arrangements and flow directions. This chapter will focus on steam turbines currently being applied to power generation.

In many cases, there are two or three LP turbines in a fossil-fueled power station. Let us suppose that about one-third or half of the steam from the exhaust of the IP turbine is used for the carbon capture plant. Steam turbines use high-pressure steam to turn electricity generators at incredibly high speeds, so they rotate much faster than either wind or water turbines.

(A typical power plant steam turbine rotates at – rpm—about – times faster than the blades spin on a typical wind turbine, which needs to use a gearbox to drive a. The reheater heats the steam (point D) and then the steam is directed to the low-pressure stage of steam turbine, where expands (point E to F).

The exhausted steam is at a pressure well below atmospheric, and, as can be seen from the picture, the steam is in a partially condensed state (point F), typically of a quality near 90%, but it is much. Steam turbines are capable of operating over a very broad range of steam pressures.

Utility steam turbines operate with inlet steam pressures up to psig and exhaust at vacuum conditions as low as 2 psia. Steam turbines can be custom designed to deliver the thermal requirements of. Condensing steam turbines are most commonly found in thermal power plants.

In a condensing steam turbine, the maximum amount of energy is extracted from the steam, because there is very high enthalpy difference between the initial (e.g. 6MPa; °C; x = 1) and final (e.g. MPa; °C; x = ) conditions of is achieved by passing the exhaust steam into a condenser (called a.

The condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption.

The condensing turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at medium intermediate. STEAM TURBINE 4 Figure 2.

TR HI is a special machine for reducing the pressure of water, designed for extremely low currents of steam with a high requirement for safe, mechanical run with a high effectiveness. The steam turbine case together with the el. generator stator forms a unit without a gear and without secondary rotating parts.

The turbine wheel is connected to a high frequency el. generator. Back Pressure Turbines: a type of steam turbine that is used in connection with industrial processes where there is a need for low or medium pressure steam.

The high pressure steam enters the back pressure steam turbine and while the steam expands – part of its thermal energy is converted into mechanical energy. The mechanical. Can be used for condensing steam turbines and for the low-pressure section of extraction steam turbines.

Steam condenser is a device in which the exhaust steam from steam turbine is condensed by means of cooling water. The main purpose of a steam condenser in turbine is to maintain a low back pressure on the exhaust side of the steam turbine.

After releasing from nozzles, the steam has to expand to a great extent for converting available energy into it to usable mechanical work. Numerical Calculation of the Steam Condensing Flow Figure 1.
