A nuclear power station (NPS), also called a nuclear power plant (NPP), generates electricity using heat from a nuclear reactor. Like other thermal power stations, it produces steam that drives a turbine connected to a generator. As of September 2023, the International Atomic Energy Agency reported 410 operating nuclear reactors in 32 countries, with 57 … Read more
A hydropower plant, or hydroelectric power plant, generates electricity by using the movement of water. Hydropower is a renewable energy source because it uses water as fuel, which does not run out. In 2023, hydropower plants had an installed capacity of 1,416 gigawatts (GW). The largest producers of hydropower in the world are China, Brazil, … Read more
Water hammer is to do with managing the loud pounding in the pipes whenever water flow ceases. It can harm your pipes in the long run. Water hammer arrestors are devices installed on pipelines while reducing water pressure helps prevent gas pipeline explosion. Have you ever switched off the water supply only to be greeted … Read more
Economisers in thermal plants prevent wastage of energy where exhaust gasses are used to heat feed water before it is taken to the evaporator. This cuts fuel usage, decreases cost, and lowers emissions. It is truly an effective way of improving the process of generation and consumption of power the world over to make it … Read more
Electrical energy comes from forces acting on electrically charged particles, like electrons in wires. This energy relies on the combination of current and electric potential, known as voltage, measured in volts, which a circuit provides. Motion, or current, is not always necessary. For instance, static electricity or a charged capacitor shows how a voltage difference … Read more
A thermoelectric generator (TEG), also known as a Seebeck generator, changes heat directly into electrical energy using the Seebeck effect. TEGs use temperature differences to produce power, similar to a heat engine, but they are more compact and have no moving parts. They are generally more expensive and less efficient than other options. When the … Read more
A Variable Frequency Drive (VFD), also known as an adjustable-speed or AC drive, controls the speed and torque of an AC motor by changing the input frequency. It also manages voltage or current variations, depending on its design. VFDs can be found in various devices, from small appliances to large compressors, improving energy efficiency compared … Read more
In particle physics, secondary emission happens when particles with enough energy hit a surface or pass through a material, causing other particles to release. This often refers to the release of electrons, called secondary electrons, when charged particles like electrons or ions strike a metal surface in a vacuum tube. The number of secondary electrons … Read more
Electricity is a type of energy that comes from other sources like chemical energy, nuclear energy, heat, and solar power found in nature. It happens due to the presence and movement of electric charge in matter. This article will explain the nature of electricity, but first, we will look at what electricity is and how … Read more
An electric motor is a device that changes electrical energy into mechanical energy using electromagnetic effects. It creates mechanical torque by having current-carrying conductors interact with a magnetic field at right angles. Different types of electric motors arrange these conductors and the magnetic field in various ways, allowing control over torque, speed, and position. In … Read more
