22/05/2019 HP Turbine (high-pressure turbine) is usually double-flow turbine element with an impulse control stage followed by reaction blading in each end of the element. There are about 10 stages with shrouded blades in the HP turbine. It the produces about 30-40% of the gross power output of the power plant unit. HP turbine
Reheat is a process of routing partially expanded steam from the HP turbine to the reheat section in the steam generator to superheat the lower pressure steam back to a high-temperature status, typically to the same temperature at the inlet of the HP steam turbine, T 1, which is typically limited by the properties of the blade material. The reheated steam is further fed into the LP steam ...
High-Pressure Turbine is a multi-layer structure that converts steam to shaft power. This is more efficient but requires a lot more steam to kick start the turbine and keep the turbine going compared to Turbine. It has a total of 8 stages including the steam injector ring. This structure can be connected to a Turbine Generator to directly convert shaft power to Redstone Flux(RF) and EU (shift+ ...
Cunard refused to accept the ship and no-one knew what the problem was until engineers opened the turbines for inspection in January 1969 and saw the extent of the failure: the rotor blades of one of the stages of the starboard high-pressure turbine had been stripped off. They had jangled inside the turbine, got caught up in other rotor blades, and stripped those off in turn. After much ...
08/04/2019 The high-pressure exhaust gas should be released and it will have no way but backward! Now keep this structure in mind and imagine I put a set of turbine blades in the path of this high-pressure back-fired exhaust. You see that the release of mechanical energy which is mostly in a “linear” backward direction will mostly transform into kind of “rotational” movement of turbine shaft and ...
Each unit had two turbine lines and therefore two generators per unit. One line incorporated a high-pressure (HP) turbine and two low-pressure (LP) turbines. The second line incorporated two intermediate-pressure (IP) turbines followed by two low pressure turbines. The steam was fed into the HP turbine first, then reheated and fed into the two IP turbines on the second line. After expansion in ...
09/12/2014 By the time the air gets to the LP turbines and the pressure is dropping, it takes 4 stages to extract every last drop of power from that low(er)-pressure exhaust. Which is the important power from the point of view of flight thrust, since it is what drives the fan, which is producing 75-85% of the total thrust (5:1 bypass ratio).
18/06/2015 Turbine is only ONE, as per our convince we are calling and divided it into HP IP LP turbines. we can make turbine with single shaft without a name HP IP LP, this was applicable for small turbine which we can use in small capacity plant and co-gen...
A steam turbine should simply harness as much rotational energy as possible from the steam pressure as possible using an intelligent blade layout. However, the compressor and turbine work together in a gas turbine from a technical viewpoint, but perform opposing functions from a physical viewpoint. A compressor acts like a pump. It sucks air in with its blades and compresses it to a high ...
The high pressure turbine flow meter body is machined from solid Alloy A286 which has a very high yield strength allowing the turbine to be used at extreme pressures. The rotor is machined from 431 stainless steel solid bar and has been specially designed with a reduced number of blades and shallow blade angle for liquids containing entrained solids. Heavy duty tungsten carbide bearings make ...
01/12/2019 Cooling flow of a first stage high pressure turbine nozzle guide vane (HPNGV) may account for up to 13% of core flow in modern gas turbine engines . This is of great importance regarding the fact that 1% of cooling air is a loss of approximately 1% specific fuel consumption . Therefore efficient utilization and control of turbine cooling flows are essential for achieving high efficiency engine ...
The gas generator section consists of a compressor, combustor, and high pressure (HP) turbine. The gas generator's purpose is to produce a hot expanding gas for use in the power turbine.

If high-pressure, high-temperature steam is partially expanded through a turbine, the efficiency can be increased by returning the steam to the steam generator and reheating it to approximately its original temperature before feeding it back to the turbine. Single reheat turbines are common in the electric utility industry. For very large units, double reheating may be employed. Nonreheat ...

The stress sources presented here will focus on two crucial components of high-pressure turbine (HPT), the blades and the disc. These stresses are responsible for the development of failure mechanisms like creep and low cycle fatigue. Blade Stress Sources. The main stress sources in the HPT blades are the following: The centrifugal load, which acts at any section of the airfoil or shank and is ...

Product - VBSE High Pressure Turbine Bypass Valve The VBSE is a steam conditioning valve used for steam throttling and desuperheating through spray water injection, directly at the outlet. Used for start-ups and load reje ction, they bypass the steam to various reheat lines until the steam temperature matches the turbine blade temperature. With a range of available body materials, the VBSE ...

High-pressure turbines: ≈ 0.5 – 0.65 Low-pressure turbines: ≈ 0.9 – 1.0 The turbine must provide the required shaft work (Δh 0) and run at the same speed as the compressor. Hence is essentially fixed. The “Smith Chart” is then used to guide the choice of in the preliminary turbine design. 142 IB-ATE-nts10.01.doc Axial core compressor (page 105): For compressors there is no ...
20/03/2019 The non-condensing steam turbine uses high-pressure steam for the rotation of blades. This steam then leaves the turbine at the atmospheric pressure or lower pressure. The pressure of outlet steam depends on in the load, therefore, this turbine is also known as the back-pressure steam turbine. This low-pressure steam uses for processing and no steam is used for condensation. The
