Thermal stations can be private industrial plants and central station. Article 29-1. less( 12 to 15 min) more ( 1 to 2 . Steam must be of the highest quality. The company has seen exponential growth over the past 30+ years, ultimately becoming the premier alternative to the OEM for non-union turbine services. Also, as part of the project, GRDA signed a 25-year long term service agreement with Mitsubishi Power. then. Steam and Gas Turbine Control Systems. of the fossil fuel is transformed into steam thermal energy by the boiler, then it is transformed into rotational mechanical energy by the turbine, and finally it is transformed into electric energy by the generator. The Excitation system generates variable DC voltage and current to the rotating field to regulate the terminal voltage of the generator within the permissible operating range. This maintenance checklist is intended for the GE Field Service Engineers. Repair. Power Plant Design, Abacus Press. Steam and gas turbines are so highly efficient and extremely reliable, it's no surprise they have been around for a long time.

In 2001, TGM added a combustion turbine service division, and a generator service . heat ratios, often . Type and quality of fuel Condensate, contaminants, etc Starting Frequency Thermal cycles Load cycles Thermal cycles Environment Abrasive and corrosive condition. Alternatively the exhaust steam may be used for process purposes. Installation and maintenance of the steam system are important issues, and must be considered at the design stage. The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam Turbine Maintenance Frequencies and Tasks Frequency Maintenance Task. General Provision . Our various online learning solutions will help you train your personnel anytime, anywhere. steam flows, acceleration of rotors, vibrations, etc.). It includes heat exchange and energy conversion equipment.] Depending on power and steam load . Although the gas turbine must be started by some external means (a small external motor or other source, such as another gas turbine), it can be brought up to full -load (peak output) conditions in minutes as contrasted to a steam turbine plant whose start up time is measured in hours. Summary. Steam trap—a device used to remove condensate or liquid from steam systems, p. 294. 50% 75% 100% 125% 150% 175% 200% 300% 400%. Impulse steam turbine: The basic idea of an impulse turbine is that a jet of steam from a fixed nozzle pushes against the rotor blades and impels them forward. CHAPTER TWO: Boiler Operation Maintenance & Safety Study Guide 2.1 Boiler Design and Construction Boiler: A boiler is a closed vessel in which water is heated, steam is generated, superheated or any combination thereof under pressure or vacuum by the direct application of heat from combustible fuels or electricity. 20 to 25 yrs. The primary focus on graphics/animations in the steam. Advantages And Disadvantages Of A Thermal Power Plant Advantages: Maintain reliability and availability. Steam turbine maintenance is of high importance to keep the steam turbines efficiency high and to conform to safety standards to avoid any unforeseen dangers. Often turbine uptime periods can be for 5 years and so if a control becomes obsolete in that period it puts the plant at risk. The term generator used in this Color Black White Red Green Blue Yellow Magenta Cyan Transparency Opaque Semi-Transparent Transparent. The steam turbine is a machine that transforms steam's heat energy into mechanical energy. The This kind of FFPPs is also called steam power plant, and depending on the operating steam pressure . heat ratios, often . As because of this increased velocity in the steam, it develops energetic pressure on the device blades where then the shaft . The once well-cared-for work horse of the industry, the steam turbine has become a maintenance afterthought as funds are reallocated to GT issues. A Steam Turbine is an engine that converts heat energy from pressurized steam into mechanical energy where the steam is expanded in the turbine in multiple stages to generate the required work. Steam Turbine - Maintenance Familiarization (GE Design) - (Distance Learning) Steam Turbine - D11 Operation (Distance Learning) Online Courses. A furnace, steam turbine, generator, and other auxiliaries make up a steam power station. TRAINING MANUAL ON BASIC ASPECTS OF STEAM TURBINE MAINTENANCE 3. Font Size. maintenance cost is relatively low. Our steam turbine supervisors have experience with the leading domestic and European manufacturers. • Single-shaft gas turbines have all compressor and turbine stages running on the same shaft • Two-shaft gas turbines consist of two sections: the gas producer (or gas generator) with the gas turbine compressor, the combustor, and the high pressure portion of the turbine on one shaft and a power turbine on a second shaft (Figure 2). The steam is then used to rotate the steam turbine. Boiler feedwater is pressurized with a single HP boiler feedwater pump (BFP), powered by an electric drive for the 400- and 600-MW cases and a steam turbine drive for the 900-MW case. They gener ate power by burning natural gas in a gas turbine and use residual heat to generate additional electricity from steam. The power generation equipment was designed for the GRDA's new Unit #3 power generation facility in Chouteau, Oklahoma, USA. The Power Plant Technical Program utilizes online courses tailored to the needs of the operator and engine type. Three basic types of steam turbine are used to generate power as a by-product of process or exhaust steamml: condensing, pass-out condensing, and back-pressure. GAS TURBINE OPERATION AND MAINTENANCE. The drive for improved reliability and availability resulted in the industry backing away from both the 1050°F steam temper- atures which were common in the late '50s and early '60s and the 3500 psig supercritical throttle Turbine trips on low main steam pressure. Steam turbine operation and performance require the correct steam pressure at the tur­bine inlet and high steam quality (steam without condensate entrapment) to ensure high turbine reliability. These are manufactured for outputs from 50 kW e to 30 MW e.Most industrial installations are in the range 1-5 MW e.A reduction in the exhaust pressure effects a . [ This provides a follow up of basic engineering cycles with applications to conventional power plants. deliver relatively large amounts of thermal energy, with electric-ity generated as a byproduct of heat generation. P2M FTUI September 2008. Irteza Hossain Faculty, BSME f Turbine Steam Turbine A steam turbine is a prime mover in which rotary motion is obtained by the gradual change of momentum of the steam. Steam Turbines. Video using http://www.bin95.com/cbt.htm Steam Turbine Training and Governing System Training software. From the control valves the steam passes to the turbine casing. deliver relatively large amounts of thermal energy, with electric-ity generated as a byproduct of heat generation.
