The achievement of Einstein's Law

Ernest Walton In 1932, the English scientists C.D.Cockcroft and E.T.S.Walton tested the validity of Einstein's law in practice, he deliberately bombard the lithium with a high-speed proton that was composed of alpha particles and a large amount of energy. The previous nuclear reaction was associated with a mass loss of 0.0186 atomic mass units. E.T.S.Walton was found...

The idea of nuclear energy

The reaction of nuclear fission is the interaction in which high thermal and light energy is produced in addition to particles such as beta and alpha. Nuclear energy is released by bombarding the nucleus 235 of neutrons as in following picture. This collision results in a new molecule of unstable that quickly breaks into two molecules and an average of 2 to 3 neutrons, thus...

Nuclear bonding energy

The nucleus of helium consists of proton and neutronin, It was supposed to be the relationship between them as in the following Figure The nucleus of the helium nucleus is 4,0015 units of atomic mass. The proton mass is 1.0073 atomic mass units. Neutron mass is 1.0087 atomic mass units. Since the nucleus of helium consists of proton and neutronin, the mass of the...

Nuclear power plants

   Nuclear generating plants are a kind of thermal generating station, because they operate by heat in the same way as generating steam. Then this steam rotates the turbines, which rotate the rotor from the electric generator and generate electrical energy on the stationary parts of the generator.    The main difference between conventional steam stations...

The electrical grid

Thomas Edison created the world's first power plant in New York in 1882, and after several unsuccessful attempts, he succeeded in generating a continuous electric current. "i have not failed i just found 10000 ways that won't work meaning." Importance of interconnected electricity network In all countries of the world, the power stations within each country are...

Classification of electrical power plants

It can be classified into two types of power plants: conventional plants, renewable energy. One of the most popular types of conventional power plants: Thermal Power Stations Gas Turbine & Combined cycle Diesel Power Stations Nuclear Power Stations Hydroelectric Power stations The most famous types of new and renewable power plants: Wind Power stations Solar...

Power measurement units

   Since power generation is a process of energy conversion, we should refer here to energy measurement units. Energy is generally (mechanical, electrical, or thermal) measured by the Joule unit. In the case of mechanical energy  Mechanical energy can be expressed in three different images (all images of the same energy but with different transformations): Potential...

The most important sources of energy

The sources of energy are two types: 1- Fossil Fuel: is the remains of organisms from plants and animals that have been buried deep underground for many years and It was subjected to very high temperatures and pressure, which led to the concentration of carbon in it and its transformation into fossil fuels. One of the most important examples of fossil fuels is coal,...

Electric power system

What is the power system? This system consists of three basic systems: 1-  Power generation system: which includes several topics systems, including: unified networks, control of generating capacity, and types of stations. 2- Power Transmission System: This system is divided into two parts: Overhead Transmission System and Underground Cables,...

How does Blackout happen?

One of the dangers in the electrical network is the occurrence of so-called full darkness or blackout, and represents a failure of the network maintains constant voltage and frequency, leading to the exit of all generating units from the service and then outages electricity for all loads. The electrical grid, as we know, is made up of power plants connected to each other...

EXHAUST SYSTEM WITH SILENCER

    Function of Exhaust System: −The exhaust system guides exhaust gas from the gas turbine via the exhaust diffuser to the heat recovery steam generator (HRSG) of a combined cycle power plant and finally to the atmosphere through the main stack.−After leaving the last stage of the gas turbine, the exhaust gases are directed through an exhaust system,...

GAS TURBINE - STARTING SYSTEM

1-STARTING SYSTEM  GT starting system used here is Static Frequency Converter (SFC).   When all permissive of GTG are met and auxiliary checks are satisfied, GTG TCS sends to DCS a signal of “READY TO START”. On obtaining the signal, DCS sends GT start signal to GT TCS. The gas turbine is started up by turning the generator via the starting frequency converter...
