General Instrumentation Of A Power Plant - 1124 Words

General Instrumentation in a Power Plant In a Thermal Power Plant, Chemical Energy of fuel is converted to Electrical Energy. Actually this energy conversion takes place in different stages. Firstly, in Boiler, the chemical energy in fuel is converted into heat energy. During process of combustion the carbon, sulphur etc available in the fuel reacts with air and liberates heat and flue gases. This heat is absorbed by the water-walls of the furnace and steam is generated. Secondly, in Turbine this heat energy, in the form of heat energy is converted into mechanical energy. And Finally, in Generators, which is coupled with the turbine, the mechanical energy is converted into electrical energy. Therefore, a Thermal Power Plant can be regarded as a process industry. Now, for successful completion of the process, a good number of process parameters need continuous monitoring which needs instrumentation. Just like other process plant, the instrumentation system of a thermal power plant has two parts:- †¢ Measurement: It deals with measurement of different parameters of the process by deploying different sensor which is mainly known as primary instrument and operating personnel by displaying it on indicator or recording it on recorder or storing it in Data Acquisition System(DAS) or in some cases, by generating audiovisual alarm signal protective signal. Indicator, Recorder DAS are mainly known as secondary instrument. †¢ Control: It takes care for automatic/manual control ofShow MoreRelatedImplementation Of Light Fidelity ( Li Fi ) On 3rd Gen Modular Projects839 Words   |  4 Pagesimplementation of Light Fidelity (Li-Fi) on 3rd Gen Modular projects (such as Oil Gas, chemicals, petrochemicals, power plants and other processing industries).

Some remote areas, which don’t have access to electricity, need some innovations to be done for energy production. Although, we have plenty of non-renewableRead MoreA Brief Note On The Mile Island Nuclear1424 Words   |  6 PagesNuclear Paper Nuclear power is a useful resource, but it can also be dangerous in certain cases. March 28, 1979 is an example of one of these situations. On that date, the Three Mile Island (TMI) power plant in Pennsylvania experienced the â€Å"worst accident in the history of commercial nuclear power in the United States† (Three Mile Island, 2014). Located near Harrisburg, Pennsylvania, the plant, as seen to the left, had originally been built to locally provide electricity and power. For five years, theRead MoreESWBR final Essay1189 Words   |  5 Pages Nuclear power plants provide the most economically efficient, safe, and sustainable source of power generation available to our generation; however it comes with it’s own set of issues that must be dealt with to mitigate any potential harm to the environment or population. One of the larger issues is that once the reactor has attained initial criticality, it is never truly â€Å"off†. The reactor will still produce heat due to decay of non-stable isotopes within it caused by fission. Because decayRead MoreRisk Management in Hydro Power5207 Words   |  21 PagesManagement In Hydro Power Plants – 18th African Hydro Symposium October 2006 By Joshua Chirikutsi – Zimbabwe Power Company- Kariba South Power station Abstract Hydro power plants like any other business encounter risks in all areas of its operations, but especially in the areas of producing and marketing electricity.
