Steam turbin memerlukan gear box sebagai penyalur tenaga putaran yang dihasilkan oleh turbin. Gear box itu harus berfungsi sebagai reducer gear yang melakukan reduksi terhadap putaran turbin sesuai dengan kebutuhan putaran yang dihasilkan. Misal dari high to low atau low to high. Dalam hal ini kebutuhan dan kapasitas serta aspek-aspek yang lain juga harus diperhitungkan jangan sampai terjadi over load yang akan mengakibatkan kerusakan fatal atau kekurangan tenaga untuk melakukan putaran sehingga tidak maksimal yang berakibat pada pemborosan energi. Steam turbin memiliki putaran yang sangat tinggi dan membutuhkan coupling sebagai penghubung dengan gear box. Menurut saya yang terbaik adalah fluid coupling, dimana pada saat awal steam turbin berputar, tidak akan melakukan hentakan atau sentakan secara mendadak terhadap shaft gear yang dapat mengakibatkan kerusakan pada shaft gear seperti melintir, patah/putus. Tetapi percepatannya bertambah secara bertahap sehingga memiliki kecepatan yang sama dengan steam turbin.

What does a gear box on a wind turbine do?
The gear box increaces the rotational speed from about 30-60. The gear box is very costly and heavy.
How does a wind turbine operate?
The Wind Turbine Generator (WTG) is broadly divided into three parts. • Tower • Nacelle • Rotor The tower of wind turbine generator supports the nacelle and the rotor. The nacelle contains the key components of the wind turbine, including the gear box, the electrical generator, control panels etc. The rotor blades convert the kinetic energy of the wind to electrical energy through gear box and generator. The hub of the rotor is attached to the gear box. The gear box has a low speed shaft for its input. The high-speed shaft of gear box rotates at approximately 1500 revolutions per minute (RPM) to drive the electrical generator system. The heart of the wind turbine is its controller, which is responsible for the operation of the whole turbine. The embedded software in the controller monitors the various inputs and other condition and controls/actuates the outputs accordingly.
What the function of gland steam condenser?
Gland staem condenser is meant for condensing the steam whichwas used for sealing the LABYRINTH GLAND and reusing it d cycle. It is then passed through d drain cooler and LP heaters and so on......
What is turbine rated speed and What is maximum speed rise of steam turbine?
Turbine rated speed varies mainaly on the factors of Generating frequency and means of coupling to generator (viz trough a gear box or directly coupled and no.poles in generator). For exmple a 50hz generting frequency and a bi-pole genarator the turbine speed is 3000RPM. The allowed speed rise also depends on turbine design and generator operational range. Generaly the speed rise is restricted to Maximum of 10% of the rated speed.
What is the Function of gland box in steam turbine?
Gland is used for the prevent leakage of oil from the gland box which is made up of copper or brass and gland box function is to support the glands which are made up of cast iron.This is called oil gland. steam gland is used for prevent the leakage of steam which exhausts air and which helps build up the vaccum in condenser is called steam gland.
How do steam engines generate force?
Steam at higher pressure and temperature - hence high energy contents - is fed via a valve into each end of the cylinder in turn. There its pressure forces the piston along the cylinder, hence turning the engine's crank to which the piston is linked by piston-rod, crosshead (a pivot on a sliding block) and connecting-rod. . The valve is driven in turn by an arrangement called the "valve gear" from the crankshaft, and this controls both the engine's direction of rotation and the "cut-off". This is the point in the piston stroke at which the valve closes so the steam already in the cylinder completes its work by expansion approximating to the normal [ (Pressure X Volume) = a Constant ], law of the behaviour of gases. . On steam locomotives, steam road vehicles and reciprocating marine engines the valve-gear's settings can also be controlled by the driver to change the forward-reverse (ahead / astern) direction as well as adjusting the cut-off for efficient running. . The above describes the reciprocating steam-engine, as on a railway locomotive. In steam-turbines the force is generated by a combination of impulse and reaction as the steam passes from the initial, inlet nozzles and through the rotor blades and fixed guide-vanes of each stage of the turbine. A turbine cannot be reversed so where this is necessary, as on a more-modern steam-ship or in a nuclear-powered submarine, and to reduce the high speed of the turbine to the low speed of the final drive, the turbine is linked to the drive through a reducing / reversing gear-box.
What is the difference between gear box cover and gear box?
The actual gear box is the area off gears.....and the gear box cover .....covers that area
What are types of steam turbine gland?
Steam turbine glands are typically categorized into two main types: stuffing box glands and mechanical seal glands. Stuffing box glands use packing materials to seal the steam and prevent leakage, while mechanical seal glands employ a rotating seal to achieve a tighter, more reliable seal. Each type has its advantages and is chosen based on factors like operating conditions, maintenance requirements, and leakage control. Additionally, gland sealing systems can be further optimized with the use of auxiliary systems like gland steam systems to enhance sealing performance.
How can I build my own steam box for cooking purposes?
To build a steam box for cooking, you will need a wooden box with a tight-fitting lid, a steam generator, and a way to insert and remove food. Drill holes in the box for steam to enter, place the food inside, and seal the lid. Connect the steam generator to the box and heat it to create steam for cooking.

What are the five parts of the wind turbine?
Tower, blades, nacelle (casing around the inside parts of the turbine), hub (the front of the nacelle/looks like the centre of the blades), gear box transmission (not needed or included in all wind turbines), generator (to turn the electricty from kinetic to electrical).
