Shall have an adequate margin between critical speed and the running speed to ensure smooth running. The efficiency of small simple steam tur bines is poor. Bottoming cycles, for instance, extract fluid energy that is at a lower pressure and temperature than a turbine in a conventional power plant.

The bore of the discs is made 0. Generally speaking, the higher t he pressure ratio across a turbine, the greater the expansion and the greater th e temperature drop. Vacuum pressed impregnated mica elastic high voltage insulation: Reporh the reaction type of blades, the heat d rop of the stage is distributed almost equally between the guide and moving blad es.

BHEL has supplied generating equipment to various utilities capable of generating over MW power. Fabrication Large size fabricated assemblies or components III. Stator winding is done by placing stator on rotating installation.

Due to new rese arches in the manufacturing field, the advancement has come to this extent reprt every different aspect of this technology has become a fullfledged fundamental a nd advanced study in itself.

The pilot exciter is a PMG permanent magnet generator. Secondly, the driven machine may be a variable speed machine like a compressor or a boiler-feed-pump.

Maintaining the gas pressure inside the machine at the desired value at all the times. Pitch of a blade is the circumferential d istance between any point on the profile and an identical point on the next blad e. Principal behind this that PMG is mounted on the common shaft which generate electricity and that id fed too yoke of main exciter Fig.

These secondary proce sses are mainly required for achieving dimensional accuracy and a very high degr ee of surface finish. Thes e can occur due to manufacturing inaccuracies, like pitch errors, setting angle variations, inlet and outlet edge variations, etc. Insulator and bushingCeramic liners. The approximate area of these plant is a follows: This type of damping is because of the inherent damping properties of the ma terial which makes up the component.


It is engaged in the design, engineering, manufacture, construction, testing, commissioning and servicing of a wide range of products and services for the core sectors of the economy, viz. The Company has als o transferred a few technologies developed in-house to other Indian companies fo r commercialization.

Sophisticated heavy casting and forging of creep resist ant alloy steels, stainless steel and other grades of alloy meeting stringent in ternational specifications.

In ca se the frequencies of the blades tend towards resonance due to manufacturing ina ccuracies, tuning is to be done on the blades to correct the frequency. A small c learance between the discs prevents thermal stress in the shaft. The steam pressure decreases. SK blades have 4-fo rk roots for all sizes. The top strip are provided with haridwaar slots of same cross-section and spacing and used on the rotor winding.

Alternate arrangement hollow and solid conductors ensure an optimum solution for increasing current and to ttaining losses.


In fact, the steam will issue from the nozzle in the form of a high-speed jet. The Human Uaridwar Development Ins titute and other HRD centers of the Company help in not only keeping their skill s updated and finely honed but also in adding new skills, whenever required. The power plant equipme nt manufactured by BHEL is based on contemporary technology comparable to the be st in the world and is also internationally competitive.

The service division includes a network of regional offices throughout India. harldwar

The casing is heavy in order to withstand the high pressures and temperatur es. BHEL has proven turnkey capa bilities for executing power projects from concept to commissioning, it possesse s the technology and capability to produce thermal sets with super critical para meters up to MW unit rating and gas turbine generator sets of up to MW unit rating.

This depends on the type of exciter viz. Integrity and fairness in all matters. It achieved a sales turnover of Rs.

The shaft is rigidly coupled to generator rotor and exciter rotors are re;ort supported on these bearings. Beside above, all kinds of the future ghel must know the basic requirements of workshop activities in term of man, machine, material, methods, money and other infrastructure facilit ies needed to be positioned properly for optimal shop layouts or plant layout an d other support services effectively adjusted or located in the industry or plan t within a well planned manufacturing organization.

There is a conversion of heat energy to kinetic energy as the h eat energy from the decrease in steam enthalpy is converted into kinetic energy by the increased steam velocity. Wotan CNC horizontal boring machining. Its operations are spread over 11 manufacturing plants and number of engineering and service divisions located across the country. Continuous circulation of gas inside the machine through a drier in order to remove any water vapor that may be present in it 5.

Bearing have provision for vibration pickup to monitor shaft vibration. This happens with the help of AVR regulator which means automatic voltage regulator.

The thermometer should be fixed in the slot but outside the coil insulation. So I would like to express my s incere thanks to my mentor MR. These different designs engage the steam in a different garidwar so as to turn the rotor 3.

The following termino logy is used in the subsequent sections. Because of this reason, the d amping elements in blades generally incorporate a feature by which the vibration al energy is dissipated as frictional heat. Cm — capacitance with respect to other winding called mutual capacitance. It buel not include the transportation, handling or storage of partsas they are not directly concerned with the changes into the form or dimension s of the part produced. There are more than hhel of Governor.

Thermal Power Station Plant.
