Conductivity can range from 7,000 microsiemens per centimeter (µS/cm) in a low-pressure industrial boiler to under 10µS/cm in a high-pressure boiler in a steam power plant.
The turbine includes a complete oil system for supplying the grease. 1. steam entrance. 2. steam exit. 3. turbine case. 4. base frame. 5. High frequency generator Running a steam turbine together with a steam reducing station. The steam turbine automatically reduces the pressure of steam from higher value to the required lower value. The generator electricity output is tied to the amount of steam.
The steam generating boiler has to produce steam at the high purity, pressure and temperature required for the steam turbine that drives the electrical generator. Geothermal plants do not need boilers because they use naturally occurring steam sources.
Jul 29, 2016· Steam turbine flow & operation At this point in the expansion, the steam is sometimes returned to the boiler and reheated to a high temperature and then returned to the steam turbine for further (safe and reliable) expansion. In a few large, extremely high-pressure steam turbine systems, double reheat systems can also be installed.
Boilers are high pressure and temperature systems used for generating steam to drive steam turbines for electricity generation. If, due to any reason of operation or malfunction in equipment or controls, the operating pressure in the system goes above the safe limit of the material of construction, it
Nov 28, 2016· Flow through turbine. For Example, we have 5 Turbines in our plant, one runs with 8MW load at 64Kg/cm2 steam pressure and 35tph flow 30MW runs at 105Kg/cm2 of steam pressure and 125tph flow 27MW runs at 112Kg/cm2 of steam pressure and 115tph flow. and so on.
A wide range of available sizes and uniform construction throughout make the Unilux HS Series boiler a plant-engineer favorite. Use our high-pressure steam boilers for central heating, process, autoclave, injection process, main-plant distribution systems or anywhere clean, dry steam
Boiler water treatment for steam boilers and high pressure steam turbines. Boiler water treatment is a central element in the efforts to achieve an unproblematic and economic boiler operation as well as an optimum steam quality. Disadvantages in connection with scale formation, corrosion, frequent blowdown, and high consumption of chemicals quickly result in serious financial consequences.
Ejector for Surface Condenser. High pressure motive steam enters the jet ejector through the inlet nozzle and is then diffused. This creates a low pressure zone which entrains air from the surface condenser. In a similar type of application, steam is also the primary motive fluid for secondary pressure drainers,
May 26, 2019· Dedicated to power plants, power generation, supercritical, and heating plants as well as steam boilers, steam turbine generators, gas turbines or combustion turbines, hrsg, steam heating, pressure vessels, steam line, including ASME questions and more. Remember the forum is made up of volunteers from experts to beginners.
The boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This article briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear.
Superheated vapor (or dry saturated vapor, depending on application) enters the turbine, after it having exited the boiler, at high temperature and high pressure. The high heat/pressure steam is converted into kinetic energy using a nozzle (a fixed nozzle in an impulse type turbine or
steam turbines and generators, Koch de Portugal for erection of the steam boiler and ba by burning natural gas under high pressure in the combustio Learn More Auxiliary System Factory, Custom Auxiliary System OEM/OD
The steam from the high-pressure turbine (HPT) outlet or exhaust is returned to the boiler to reheat the steam at a temperature (generally) equal to the original main steam temperature (see Figure I/2.3-1). Reheating is done to avoid wet steam in the turbine blade, which causes erosion because of water particles in wet steam.
Steam Driven Generators: Steam Turbines and Electric Generators. A steam turbine driven generator, sometimes known as turbo generators, can be best explained by understanding a steam turbine and a generator separately. A steam turbine is a steam-driven driver. Water is heated at an extremely high temperature to convert it into steam.
In a steam power plant, high-pressure steam from a boiler is used to turn a turbine. After exiting the turbine, the steam, which is now at a lower pressure, is cooled before being pumped back to high pressure and returned to the boiler. Explain why this cooling step is advantageous, even though it involves the loss of energy as heat.
Nov 28, 2016· Pressure of steam required depends on Design load, Number of Stages, Number of Extractions, Max. Flow through turbine. For Example, we have 5 Turbines in our plant, one runs with 8MW load at 64Kg/cm2 steam pressure and 35tph flow. 30MW runs at 105Kg/cm2 of steam pressure and 125tph flow. 27MW runs at 112Kg/cm2 of steam pressure and 115tph flow. and so on.
Typically most of nuclear power plants operates multi-stage condensing wet steam turbines (the high pressure stage runs on saturated steam). In these turbines the high-pressure stage receives steam (this steam is nearly saturated steam x = 0.995 point C at the figure) from a steam generator and exhaust it to moisture separator-reheater
Superheating Mechanics. Note this as Example 4. The main steam enthalpy becomes 1,474.1 Btu/lbm and the turbine exhaust enthalpy is 871.0 Btu/lbm. The turbine work output rises to 603.1 Btu/lbm (176.7 MW at 1,000,000 lb/hr steam flow), and the efficiency increases from 40.6 percent to 42.9 percent.
