Losses in steam turbine

-

There are several types of losses that occur in a steam turbine, which can impact its overall efficiency. These losses include:

1. Friction Losses: Friction losses occur due to the resistance between the moving parts of the steam turbine, such as bearings, seals, and other components. These losses can lead to increased wear and tear on the turbine components and can reduce its efficiency.

2. Windage Losses: Windage losses occur when the rotating blades of the turbine interact with the surrounding air, creating turbulence and resistance. This can result in increased power requirements and reduced efficiency.

3. Blade Profile Losses: Blade profile losses occur due to the shape and design of the turbine blades. The shape of the blades can impact the amount of steam that can flow through the turbine and can lead to increased losses.

4. Leakage Losses: Leakage losses occur due to steam escaping from the turbine, either through the sealing components or through the blade clearances. This can result in reduced efficiency and can impact the performance of the turbine.

5. Condenser Losses: Condenser losses occur due to the inefficiencies of the steam condenser that is used to convert the exhaust steam back into water. These losses can be significant and can impact the overall efficiency of the steam turbine.

Reducing these losses can improve the overall efficiency of the steam turbine. This can be achieved through the use of improved materials, better design, and more advanced control systems. Proper maintenance and operation of the steam turbine can also help to minimize these losses and improve its performance.

OBJECTIVE Auxiliary steam is the steam that is required for various auxiliary requirements in a power plant. A part of main steam is tapped off for auxiliary steam station from MS/CRH line, after pressure reducing and de-superheating up to 16 Kg/cm 2   & 320 °C. At the HT header (16 16 Kg/cm 2    & 320⁰C) and then at the LT header (16 Kg/cm2 & 210⁰C) through desuperheater b/w the HT & LT headers. Spray water quantity required for the temperature reduction of the steam is controlled by separate spray water valve (taken from CEP discharge). TYPES OF STATIONS System consists of  two auxiliary  steam pressure reducing and desuperheating stations (APRDS). High capacity PRDS (LTPRDS)  with tapping off steam from main steam line or CRH line . Low Capacity PRDS(LTPRDS)  from HT header. APRDS SERVICES Auxiliary steam system is designed to provide steam for following systems. 1:-  Turbine  &  Turbine auxiliaries . 2:-  Boiler auxiliaries . 3:-

CONDENSATE EXTRACTION PUMP (CEP) IN A THERMAL POWER PLANT

-
Image
CONDENSATE EXTRACTION PUMP (CEP) Its Importance in Thermal Power Plant It handles water from hot well. The characteristic of that pump is that it handles water from vacuum.  Berceuse the condenser and the hot well are in vacuum bellow atmospheric pressure. No other pump has this characteristic to handle in such condition. It takes water from vacuum pressure and delivered above atmospheric pressure.   It is a vertical turbine type pump which is multi stage. It deliver water from hot well to deaerator. They may be used to pump the condensate produced from latent water vapors in any of the following mixtures: Steam condensed (exhaust from LP turbine) in condenser Make up water (dumped in condenser hot well from condensate storage tank) Flash box water LPDFT water HPDFT water Drip from ejector Drip from LPFWH   CEP for a 200 MW unit:- Each unit has been equipped with three nos. of condensate pumps installed vertically at minus four meter level in to the turbine hall.
