There are mainly three types of jet condensers. Low Level Condenser In a low-level condenser, the chamber is placed at a low height, typically beneath the steam turbine. Pumps are needed to extract the cooling water, condensate, and air from the condenser. Low level jet condensers are of two types- Let discuss this jet condenser … Read more
AC Induction motors are known for their robustness, reliability, and ease of control, making them popular in everything from industrial systems to home appliances. Yet, achieving peak efficiency in these motors is tough due to their complex math models and non-linear behavior at saturation. This complexity necessitates high-performance control algorithms like vector control for effective … Read more
Fluidization is a way to mix fuel and air to get combustion. A fluidized bed is defined as a bed of solid particles that behave like a fluid. It works by passing air evenly through the particles; at low air velocity, the particles stay still, but as the air flow increases, the particles become suspended. … Read more
What is a Power Plant? A power plant (also known as a power station or power generating station), is an industrial location that is utilized for the generation and distribution of electric power on a mass scale. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric … Read more
An operational amplifier or op amp is a DC coupled voltage amplifier with a very high voltage gain. Op amp is basically a multistage amplifier in which a number of amplifier stages are interconnected to each other in a very complicated manner. Its internal circuit consists of many transistors, FETs and resistors. All this occupies … Read more
To achieve maximum fuel combustion efficiency, complete combustion of fuel inside the boiler furnace is essential. This requires a sufficient supply of air and proper mixing with fuel. It’s also important to maintain an adequate supply of fuel particles for proper burning.The combustion process should consistently produce and maintain the designated temperature of the steam … Read more
What is a Transducer? An electrical transducer is a device which is capable of converting physical quanties into a proportional electrical quantity such as voltage or electric current. Hence it converts any quantity to be measured into a usable electrical signal. This physical quantity which is to be measured can be pressure, level, temperature, displacement … Read more
What is a Regulated Power Supply? A regulated power supply transforms unregulated AC (Alternating Current) into a stable DC (Direct Current). It guarantees consistent output despite variations in input. A regulated DC power supply is also known as a linear power supply, it is an embedded circuit and consists of various blocks. The regulated power … Read more
What is an On Off Controller? Sometimes, the control element has only two positions either it is fully closed or fully open. This control element does not operate at any intermediate position, i.e. partly open or partly closed position. The control system made for controlling such elements is known as the on-off control theory. In … Read more
An electrical surge can occur in a electrical power transmission system due to various reasons, mainly lightning and switching impulses. These surges create large transient overvoltages with steep rising fronts and slow decaying tails. This steep voltage wave travels through the network, stressing all electrical insulators and equipment in its path. That is why all … Read more
