The electronic configuration of an atom describes how electrons are arranged in energy levels and sublevels around the nucleus. This configuration affects the atom’s physical and chemical properties, including reactions with other atoms, electrical conductivity, and magnetic field behavior. What is an Electron? An electron is a negatively charged subatomic particle that orbits the nucleus … Read more
Steam flashing happens when pressurized condensate is released to a lower pressure, turning some water into steam. This process helps recover energy from condensate for different uses. In this article, we will explain what steam flashing is, how it differs from normal steam generation, how to calculate it, and its effects and applications. What is … Read more
Thermal conductivity is a property that measures how well a material can transfer heat from one point to another without moving the material itself. It depends on factors such as the structure, composition, and temperature of the material. In this article, we will focus on the thermal conductivity of metals, which are solids with high … Read more
A diode is a semiconductor device that allows electric current to flow in one direction only. It has two terminals: an anode (positive) and a cathode (negative). A diode is said to be forward-biased when the anode is connected to a higher voltage than the cathode, and reverse-biased when the opposite is true. A good … Read more
Magnetostriction is defined as the property of some magnetic materials that causes them to change their shape or dimensions when they are magnetized by an external magnetic field. The change in size or length of a material due to magnetostriction depends on the strength and direction of the applied magnetic field, as well as the … Read more
A surface steam condenser cools and condenses exhaust steam from a steam turbine. Its main purpose is to improve turbine efficiency by creating a low-pressure environment and recovering pure water for reuse as boiler feed water. A surface steam condenser consists of a shell that contains a large number of tubes through which cooling water … Read more
A transformer is a device that transfers electrical energy from one circuit to another by electromagnetic induction. Transformers are widely used in power systems to step up or step down voltages, isolate circuits, and balance loads. Transformers can be classified into different types based on their construction, winding configuration, and vector group. A vector diagram … Read more
A deaerating heater, also known as a deaerator, is defined as a device that removes dissolved gases, mainly oxygen and carbon dioxide, from boiler feedwater. These gases can cause corrosion and damage to the boiler and its parts, reducing steam cycle efficiency. Therefore, deaerating heaters are crucial for boiler water treatment and protection. Deaerating heaters … Read more
A natural draft cooling tower is a type of heat exchanger that cools water by direct contact with air. It is used in power plants, oil refineries, petrochemical plants, and natural gas plants to remove excess heat from the circulating water system. A natural draft cooling tower relies on the principle of convective flow to … Read more
A thermopile is a device that converts heat into electricity by using the thermoelectric effect. It consists of several thermocouples, which are pairs of wires made of different metals that generate a voltage when exposed to a temperature difference. Thermocouples are connected in series or sometimes in parallel to form a thermopile, which produces a … Read more
