A fan can be defined as a volumetric machine that moves quantities of air or gas from one place to another. During this process, energy transfer occurs from the machine to the fluid, converting mechanical energy into fluid energy. Fans, blowers, compressors, and pumps belong to the category of machines where energy transfer occurs from […]
An Ash Handling Plant is a critical component in thermal power stations where coal combustion produces ash as a byproduct. The plant handles both fly ash (light particles) and bottom ash (heavier particles) efficiently. Ash handling in a thermal power plant refers to the method of collecting, conveying, storing, and disposing of various types of
Thermal power plants generate electricity by burning coal, a process that inevitably produces flue gases and particulate matter known as fly ash. Fly ash is the fine residue of ash particles carried along with flue gases during combustion. These particles make up about 85% of the ash content in coal and, if not controlled, can
Air preheaters (APHs) are essential components in boiler systems, playing a unique role among boiler auxiliaries. Their primary purpose is to recover heat from the flue gas and utilize it to preheat combustion air, thereby significantly improving overall energy efficiency. This process can boost boiler efficiency by 8-12% and positively impact plant capacity and heat
Coal feeders are essential components in power plants, responsible for regulating the coal supply to coal mills. Their operation directly impacts the efficiency of boilers by controlling the load and maintaining the required pressure. In this article, we delve into the types of coal feeders, their components, working mechanisms, and speed control techniques to provide
The Bowl Mill, also known as a pulverizer, incorporates the best features of various coal grinding systems, making it an efficient and reliable choice for pulverizing coal. Its main components include: Reduction Gearbox: Transmits power to the bowl and reduces the motor’s speed. Mill Side and Liner Assembly: Protects the structure from wear and tear.
Boilers are crucial for generating steam in industries ranging from power plants to manufacturing. Defined as closed vessels with capacities exceeding 22.75 liters, they operate under high pressure to convert water into steam. This steam then drives turbines or serves other industrial processes. Over the centuries, boiler technology has evolved, resulting in more efficient and

In industrial settings, boilers play a critical role in generating the steam and heat required for various processes, from power generation to manufacturing. However, achieving efficient and complete combustion in boilers—especially when dealing with different types of fuel like coal, oil, or gas—requires a precise understanding of the principles behind fuel firing. This blog, Fuel
Coal handling plants (CHPs) are vital components of coal-based thermal power plants, responsible for receiving, processing, and transferring coal to bunkers for feeding the boilers. Let us know in detail about protection in coal handling plants and challenges. Coal handling plants must operate efficiently to ensure a continuous supply of coal, avoiding disruptions that could

A coal handling plant (CHP) in a thermal power plant is a facility that receives coal, prepares it for use, and transfers it to the coal bunker. It occupies nearly 50% area of the plant. The coal is first conveyed to a primary crusher using a combination of conveyor belts, with the feeding rate controlled by
