Thermal Power Plant DefinitionA thermal power plant is defined as a facility that generates electricity by using heat energy, primarily from burning coal, to produce steam that drives turbines.Theory of Thermal Power StationThe theory of thermal power stations is simple. These plants use steam turbines connected to alternators to generate electricity. The steam is produced in high-pressure boilers.Generally in India, bituminous coal, brown coal, and peat are used as fuel for the boiler. The bitu

Economiser DefinitionAn economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in thermal power plant before being released through the chimney. Flue gases are the combustion exhaust gases produced at power plants consist of mostly nitrogen, carbon dioxide, water vapor, soot carbon monoxide et

Thermal Power Plant DefinitionA thermal power plant uses coal, air, and water to generate electricity based on the Rankine Cycle.A thermal power generating plant works using the Rankine Cycle. It needs three main inputs to produce electricity: coal, air, and water.Coal is used as fuel here because we are going to draw the flow diagram of a coal thermal power generating plant. Coal creates required heat energy by combustion in the furnace.Air is supplied to the furnace to accelerate the combustio

What is Cogeneration ?Cogeneration DefinitionCogeneration, or combined heat and power (CHP), is defined as a system that produces both electricity and heat from a single fuel source.High Efficiency Cogeneration plants are highly efficient, with efficiency rates of 80-90%, compared to the 35% efficiency of conventional power plants. Environmental Benefits Cogeneration reduces emissions of pollutants and greenhouse gases, helping to combat climate change.Economic Advantages Cogeneration helps to i

What is MHD Generation?MHD Generation DefinitionMHD power generation is a process that directly converts thermal energy into electrical energy, bypassing mechanical stages, making it highly efficient.Faraday’s PrincipleThe principle of MHD generation relies on Faraday’s law of electromagnetic induction, where movement of a conducting fluid through a magnetic field induces electrical current.The power generated per unit length by MHD generator is approximately given by u is the fluid velocity B i

A vacuum pump is a device that removes gas molecules from a sealed chamber or container, creating a partial or complete vacuum. Vacuum pumps are widely used in various industries and research fields, such as aerospace, electronics, metallurgy, chemistry, medicine, and biotechnology. Vacuum pumps can also be used for applications such as vacuum packaging, vacuum forming, vacuum coating, vacuum drying, and vacuum filtration.In this article, we will explain what vacuum pumps are, how they work, wha

Steam power plants are still the backbone of the total power generation in the Asia pacific. Thus even a small improvement in the form of increasing the efficiency has a tremendous effect on the fuel-saving and also a reduction in emission of greenhouse gases.Thus one should not miss out on any opportunity to find out the ways and means to increase the efficiency of the steam power cycle.The idea behind any improvement or modification is to increase the thermal efficiency of the power plant.

Rankine Cycle with Closed Feed Water HeatersRankine cycle with closed feed water heaters are having its benefits and is most commonly used in all modern power plants. Closed feed water heater employs indirect mode of heat transfer, i.e extracted steam or bleed steam from the turbine transfers its heat indirectly to feed water in shell and tube heat exchanger. Since the steam and water are not mixing directly, so both steam and water circuits are at different pressures. Close feed water heater in

What is the Rankine Cycle?The Rankine Cycle is a mechanical cycle commonly used in power plants to convert the pressure energy of steam into mechanical energy through steam turbines. The Rankine Cycle’s major components include a rotating steam turbine, a boiler pump, a stationary condenser, and a boiler.A boiler is used to heat the water for steam at the required pressure and temperature as per the turbine’s requirement for power generation.The turbine exhaust is directed to the radial or axial

Carnot CycleThe Carnot cycle is a thermodynamic cycle that is known for the best possible efficiency. Carnot cycle changes the energy available in the form of heat to produce useful reversible-adiabatic (isotropic) and other processes.Carnot engine efficiency is one minus the ratio of the temperature of the hot thermal reservoir to the temperature of the cold reservoir. The Carnot cycle is known for setting the highest efficiency benchmark that any cycle or engine can achieve.Work is done by the
