An extraction/condensing turbine can be thought of as two turbines in series, with part of the extraction section flow going to the condensing section. Design power refers to expected power from performance "maps" that are at specific design inlet pressure, inlet temperature, and exhaust pressure. Expected power is the power expected from a
Extraction-condensing Turbines; Extraction Back-pressure Turbines; Mixed-pressure Turbines; Geared Turbines; Modular Design (MD) Concept. Small/mid-sized steam turbines are designed based on a modular design (MD) concept in which standardized modules for turbine components, such as governing valve chests and low pressure
For large industrial CHP applications, an extraction -condensing type of steam turbine can be used in a combined cycle plant with the steam turbine extracting a The pressurized steam is expanded to lower pressure in a turbine, then exhausted either to a condenser at vacuum conditions, or into an intermediate temperature steam distribution
Extraction Steam Turbine. An extraction steam turbine, also known as a multi-stage steam turbine or non-condensing steam turbine, is a type of steam turbine that extracts steam at one or more intermediate points along its length, rather than exhausting all of the steam at the end. The extracted steam is typically used for process
What is extraction condensing steam turbine. Steam can be obtained at each stage of the multi-stage turbine. Extracted steam can be used to meet the demand of process consumer at an intermediate pressure and left over to the condenser. At condenser, steam is condensed into feel water which ultimate returns to boiler again to
Automatic Extraction Condensing Turbine. An automatic extraction condensing turbine (AECT) is a type of steam turbine that is designed to extract steam at a controlled pressure and temperature while maintaining the required load output and using the remaining steam to condense. This makes them ideal for applications where there is a need for both
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; 275°C; x = 1) and final (e.g. 0.008MPa; 41.5°C; x = 0.9) conditions of steam. This is achieved by passing the exhaust steam into a condenser (called a surface
The document discusses extraction condensing turbines, which are used when constant pressure steam must be extracted for industrial processes. These turbines can maintain steady power output despite variations in steam demand. They operate similarly to condensing turbines but can extract low pressure steam for plant use. The document
Controlled extraction condensing type turbines are usually used in Co-generation application and offer maximum cycle efficiency to the user. Arani can also provide customized bleed along with extraction, if desired. Arani can provide Turbine for both Water Cooled Condenser and Air Cooled Condenser; Title #1.
The back pressure turbine (or the extraction back pressure turbine) is adopted in many facilities such as oil refineries, petrochemical, paper-pulp, fiber, and food industries, where large amounts of steam are required. Alternatively, a combination of a separate back-pressure and condensing turbines can be considered. Fig. 7. Back pressure
Condensing Steam Turbines : The steam expands below atmospheric pressure within a condensing turbine and then "condenses" while heating the cooling water in a condenser. The power plant is an ideal application for Condensing Turbines. The primary goal is to generate electricity using steam. The pressure of steam after it exits
A condensing steam turbine''s processes produce the maximum mechanical power and efficiency from the steam supply. However, the power output of condensing steam turbines is sensitive to ambient temperature. An extraction turbine has one or more openings in its casing for extraction of a portion of the steam at some
Extraction-type turbines are common in all applications. In some applications, when required, steam can be extracted from the turbine before steam flows through the last stage, named extraction turbine.As in back-pressure turbines, extracted steam can be used for many industrial processes, or it can be used to improve the efficiency of the
An automatic extraction condensing turbine is a type of steam turbine that is designed for specific applications where multiple stages of extraction and condensation are required. These turbines are commonly used in power plants and industrial processes where there is a need for both electricity generation and process
Condensing Steam Turbine. The condensing turbine can use the total energy of the inlet steam flow to a maximum extent. This type of steam turbine is used in power plants that are highly reliable to meet the power generation requirements. Types of
An increase of turbine efficiency and power coming from adaptive control is estimated for a group of two exit stages of an extraction/condensing turbine of power 60 MW.
A back pressure steam turbine, also known as a non-condensing or extraction steam turbine, is a type of steam turbine used in various industrial and power generation applications. Its primary characteristic is that it releases the exhaust steam at a pressure higher than atmospheric pressure, and this steam is often used for specific
Fuji Electric provides single cylinder and 2 cylinder condensing steam turbines (40 MW to 300 MW), designed for small and medium scale power plants with reheat or non-reheat cycle. The small-medium size steam turbines are well suited for a variety of applications such as fossil fuel power, biomass energy, solar thermal energy, etc.
The extraction condensing turbines are used when a constant pressure steam flow has to be extracted for process purposes. The constructional characteristics of these steam turbines are very similar to condensing turbines From the second admission valve chest it is possible to inject low-pressure steam, available in the plant to supply the power
The industrial usage of a turbine influences the initial and final conditions of steam. For any steam turbine to operate, a pressure difference must exist between the steam supply and the exhaust. This classification includes: Condensing Steam Turbine, Back-pressure Steam Turbine, Reheat Steam Turbine, Turbine with Steam Extraction
The third type, an extraction steam turbine, is a condensing steam turbine with a steam extraction port part-way along the steam turbine that can provide steam at intermediate temperature and pressure for an industrial process (see Fig. 5.2). The actual position of the extraction port will depend on the heat demand so this type of CHP plant
In order to match steam production to heat demand, there are three types of steam turbine in common use for CHP plants. These three are called a back pressure steam turbine,
Extraction-condensing turbines (ECTs) are hybrids, in which some of the exhaust steam is extracted at pressures high enough for process heating (cogeneration mode) and the rest is condensed by a
The extraction condensing turbine has more operational flexibility compared with the back pressure turbine, but equipment cost is higher due to additional extraction control valve. This type of the turbine is applied to the facilities in the mining industry, steel companies, and cement manufactures because of bigger power demand
