Design of Waste Heat Boiler 1.00 Introduction: It is a High Pressure & High Temperature exchanger to transfer heat from synthesis gas of Ammonia and generate high pressure steam from boiler feed water. Such exchangers are being designed as per International Codes viz. ASME Section VIII‚ Div-2 an American code or AD Markbleter a German code. Since it is generating steam on shell side‚ the shell is also to be designed as per IBR (Indian Boiler Regulation) code. In India and other foreign

Diametral Pitch – ratio of number of teeth in the gear to the pitch diameter. Pd = N/D Forces on Helical Gear Tooth More Pitches • Normal Diametral Pitch – diametral pitch in normal direction Pnd = Pd / cos ψ • Axial Pitch – distance between corresponding points on adjacent teeth measured in the axial direction. Need Px ≥ 2 for full helical action. Px = p / tan ψ = π / Pd tan ψ Wr Wn Wx ψ ψ Wt Tooth line at pitch diameter Wt = 33000(P) vt Wt = Tangential g Load P = Power transmitted (hp) vt = Pitch

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs

CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping. Centrifugal pumps are used for

In the axial plane‚ centering of the patella was best for the BKA group with higher trochlear rotation in the BKA group compared to TKA group. Conclusions: The results of our study show that the use of a BKA preserves the morphology of the patient especially in the frontal plane preserving the physiological tibial varus and the femoral valgus. Moreover‚ in the axial plane‚ the independent adjusting of the rotation of the trochlear implant

Introduction to Gas Turbines A turbine is any kind of spinning device that uses the action of a fluid to produce work. Typical fluids are: air‚ wind‚ water‚ steam and helium. Windmills and hydroelectric dams have used turbine action for decades to turn the core of an electrical generator to produce power for both industrial and residential consumption. Simpler turbines are much older‚ with the first known appearance dating to the time of ancient Greece. In the history of energy conversion‚ however
