Power plant Steam Turbine
generator:
1,Meeting various parameters of steam admission and
extraction.According to user\'s requirement to choose and design
steam turbine. Many speed
types can be chosen.the main mover in the thermal power
plant.
2,Applicable to self-supplied power plant and regional thermal
electric plant that not only need
electric power but also adjust thermal load in a large range such
as thermal electric power, cheemical
industry,sugar-making,paper-making,textile,food
industry.
3,Supply electric power and industrial steam,with electrc and
thermal load adjusted respectively.
4,Reasonable and compact structure,easy to install,operating
steadily and reliably.
5,Adopting DEH and full hydraulic governing system.
Steam Turbine is a kind of external combustion rotary machinery
which can convert steam thermal energy into mneed electric power
but also adjust echanical work. After steam from boiler enters into
steam turbine, it passes a series of ring type of nozzle and
movable blades by sequence, which converts thermal energy of steam
into the rotating mechanical energy of steam turbine rotor. Steam
in turbine converts energy in different way, constituting steam
turbine with different working principles.
Traditionally, the components and system of steam turbine is
divided into three categories: turbine proper, governing system and
auxiliary equipment.
Turbine proper: include casing, rotor, diaphragm, blade
etc.
Governing system: include pedestal of bearing, bearing, regulator,
steam inlet valve etc. components, control oil system and
lubricating oil system etc.
Auxiliary equipment: include condenser, HP and LP heater, extractor
etc. and return heating system, shaft sealing system and vacuum
extraction system etc.
Steam Turbine adopts advanced fully 3D flow passage design
technology, reasonable structure, and excellent performance.
Regulation and control of steam turbine adopt whole hydraulic
control system or electro hydraulic control system, meanwhile
equipped with different function of safeguard devices, which
guarantees safe and reliable operation of steam
turbine.
Steam Turbine is mainly divided into condensing type of steam
turbine, extraction type of steam turbine, back pressure type of
steam turbine, and extraction back pressure type of steam turbine
etc.
