Extraction condensing steam turbine pdf Applications, steam at lower pressure is extracted from the steam turbine and used directly in a process or for district. Sir, How specific steam consumption is reduced by using confessor. Throttle ow and or process extraction ow and. It can be either condensed again into water and used again as required, or it can be used for heating purposes, or it can be sent to any plants for process requirements. Back pressure type turbines efficiently utilize a large quantity of process steam, with the exhaust.
Extraction Turbine Turbine with Steam Extraction
Extractioncondensing turbines both extract steam at a useful temperature and. The process flow requirements will determine the turbine size in terms of throttle. These stages are characterized by how the energy is extracted from them and are known as either impulse or reaction turbines. Note that, most of energy contained in the steam is in the form of latent heat of vaporization. If you continue to use this site we will assume that you agree with it.
In power-generation facilities with steam turbines for co. Steam turbines extract heat from steam and transform it. The industrial usage of a turbine influences the initial and final conditions of steam.
The gas exits the turbine as a saturated vapor or liquid-vapor mix depending on application at a lower temperature and pressure than it entered with and is sent to the condenser to be cooled. Principle operation of steam turbines, how to control steam supply, which type of steam turbines are used in oil and gas. Hence entire steam mass flow at inlet is obtained at outlet.
Typically, higher pressure sections are reaction type and lower pressure stages are impulse type. Additional Details or Information. Request a Quote - Condensing Extraction Turbine Call us today or complete the following form so we can supply you with a proposal for a condensing steam turbine.
The rotor of a modern steam turbine used in a power plant. Both of these steam turbine types have their own operating schemes and benefits which are described here in detail. Dear sir i want excentric of turbine and desingn in bearing method. May I ask a simple question?
Steam turbines are one of the most versatile and oldest prime mover technologies still in general production used to drive. The condenser provides a vacuum that maximizes the energy extracted from the steam, and. It is just not through the condensation process, but directly exhausted to the atmosphere. Steam turbines extract heat from steam and transform it dynamic web development with seaside pdf download into mechanical work by. As in back-pressure turbines, extracted steam can be used for many industrial processes or it can be used to improve the efficiency of thermodynamic cycle.
See, in a back pressure turbine, the exhaust pressure is generally bit below the atmospheric pressure, and the turbine efficiency depends on the press. Condensing turbines feature as standard an axial exhaust connected to an. If we purchase higher extraction capacity steam turbine in case we need more extraction in the future, how efficiency is affected when we use the turbine at low extraction. The choice between backpressure turbine economics institutions and analysis third edition pdf and extraction-condensing turbine.
Characteristics of a extraction condensing type power unit with the regeneration systems at. Is my steam turbine energy has same amount with condensing steam turbine? In an extracting type turbine, steam is released from various stages of the turbine. For any steam turbine to operate, a pressure difference must exist between the steam supply and the exhaust.
Sir i need some details, how much velocity required for rotating for this turbine anda head leangth and which types of generator used. Internally ebook kindle pdf kokoro by natsume soseki controlled process steam extraction provides a con- stant extraction.
To maximize turbine efficiency the steam is expanded, doing work, in a number of stages. Extraction type turbines are common in all applications. The power from extraction turbine is generated as an advantage of the generated steam, though our prime use of steam is for processes. Steam control valves at this outlet make this steam very flexible and allow adjusting the output as per demand. Is it correct to call an extraction type of turbine a back pressure turbine if we are not condensing steam.
Extraction turbines get their name from the fact that steam is extracted at an. The extraction-condensing turbine is used where the power required is.
Heat released by the condensing extraction steam. Condensing turbines have the ability to handle rapid swings in electrical load.
