Predicting the operational performance of your turbine based on lube oil analysis can have a positive impact on unit reliability and maintenance metrics. There are many testing options for both gas and steam turbines—to provide data about turbine performance and oil …
1.1.1 Steam turbine " Steam turbines are machines that are used to generate mechanical (rotational motion) power from the pressure energy of steam. Steam turbines are the most popular power generating devices used in the power plant industry primarily because of the high availability of water, moderate boiling point, cheap
The Reject-to-Power Method Fuels Reject-to-power plants can be fuelled using fine and large grain waste, as well as fibres mixed with bio-slurry from the processing of used paper. Biomass residues, alternative fuels, sewage sludge (as sewage sludge mono-incineration) and surrogate fuels can equally be used. The plants are conceived in such a way that fuels...

Independent oil system – less troubles withImpurities and oil filter cloggingControl valve (RURV) of single-stage turbine in connection with high-pressure electro-hydraulic system has very important advantage in simplicity compared to low-pressure control system (used with steam turbine).
Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9. After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts
Steam section has a turbine, which produces a tremendous force and gives a higher rate of discharge. They can be vertical or horizontal in design. Working of COPT. COP is driven by a steam turbine, which gets a high pressure steam of 16kg/cm 2 from a boiler. Generally, oil tankers have two auxiliary Boilers of nearly 16kg/cm 2 working pressure ...

Steam flows steadily into a turbine with a mass flow rate of 26 Kg/s and a negligible velocity at 6 MPa and 600°C. The steam leaves the turbine at 0.5 MPa and 200°C with a velocity of 180 m/s. The rate of work done by the steam in the turbine is measured to be 20 MW. If the elevation change between the turbine inlet and exit is negligible, Determine: (a) The rate of heat transfer associated ...

Steam Turbine Lubricating oil Characteristics. Mostly turbine of steam power plant may have its rotational 3000 rpm to produce required power. Due to friction the temperature of bearing, rotor may increase which, combined with other factors, may leads to the failure of bearing hence produce a serious damage to turbine and plant.
Steam lines should ideally be arranged to fall in the direction of flow, at not less than 100 mm per 10 m of pipe (1:100).This slope will ensure that gravity (and the flow of steam), will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed (see Fig. 15.4).Any steam lines rising in the direction of flow should slope at not less than ...
Steam and gas turbines are so highly efficient and extremely reliable, it's no surprise they have been around for a long time. In fact, the turbine has a rich history that dates back to the period of BC when the first predecessor to the hydro-turbine, the water wheel, …
Most gas and steam turbine OEMs require a turbine oil with a VI of at least 90, which is met by most turbine oil suppliers. The VI for turbine oils should not vary in-service, because turbine oils typically do not contain VI improvers and therefore do not need to be tested routinely. Rotating Pressure Vessel Oxidation Test (RPVOT) - ASTM D2272
The steam reaches temperatures of up to 1,000 degrees Fahrenheit and pressures up to 3,500 pounds per square inch, and is piped to the turbine. 3. Steam turns the turbine The enormous pressure of the steam pushing against a series of giant turbine blades turns the turbine shaft.

By-product steam from the gasifier coolers (some 40% of the total steam supply) is also superheated in the HRSG and the two streams of steam enter the steam turbine which drives its own generator. Some 20 IGCC plants, in various forms, some with other gasifiers but most using oxygen, are now operating or are in the process of construction.
49. What is the effect of friction on flow of steam through a nozzle ? To decrease both mass flow rate and wetness of steam. 50. Why gas turbine power plant needs efficient compressor ? Because a large portion of turbine work is eaten away by compressor and its inefficiency will affect net power output and cost of generation. 51.

This steam is carried to IP turbine after which it is directly send to LP turbin. The steam reaches to LP turbine at a pressure of 1.5 Kg/cm2. The steam is also carried from turbines to LP heaters and HP heaters to heat the water entering the boiler. After loosing its pressure and temperature steam is taken to the condenser.

Since the production of Japan's first land steam turbine (500 kW) in 1908, MHPS's steam turbines have accumulated over 360 GW of output to date. The main reason why steam turbines continue to be widely used even today is that steam turbines have a proven track record of supplying stable electric power successfully for many years.
