What is simple steam power plant?
The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. The waste heat from a gas turbine can be used to raise steam, in a combined cycle plant that improves overall efficiency.
What is the basic working principle of steam power plant?
A steam power station basically works on the Rankine cycle. Steam is produced in the boiler by utilising the heat of coal combustion. The steam is then expanded in the prime mover (i.e.., steam turbine) and is condensed in a condenser to be fed into the boiler again.
What is the cycle of operation of steam power plant?
The steam Rankine cycle is one of the highest utilized types of thermodynamic cycles for electricity production in the world [1]. The steam power stations run on Rankine cycles using steam as a working fluid. The simple ideal Rankine cycle is in fact the most basic vapor power cycle.
Which is important component of steam power plant?
What are the components of a Steam Power Plant? A furnace, steam turbine, generator, and other auxiliaries make up a steam power station. The boiler produces steam at a high temperature and pressure. The steam turbine is a machine that transforms steam’s heat energy into mechanical energy.
Which turbine is used in Steam Power Plant?
In order to match steam production to heat demand, there are three types of steam turbine in common use for CHP plants. These three are called a back pressure steam turbine, an extraction steam turbine and a condensing steam turbine. Each type will suit a different configuration of plant.
What is caking in power plants?
What is caking in Power Plants? Explanation: When many bituminous coals are heated, they soften and form a plastic mass that swells and re solidifies into a porous solid. Explanation: Because this coal is used to generate steam.
What are the components of a steam power plant?
What are the components of a Steam Power Plant? Explanation: A Steam Power Plant has the sequence, Boiler, Turbine, Condenser, Pump.
What is the advantage of steam power plant?
Power Generation/Steam Power
| Advantages | Disadvantages |
|---|---|
| Cheap coal is used | Air pollution from smoke fumes |
| Can be installed anywhere near fuel & water supply | Costs more to run compared with other types of power stations |
| Requires less construction space | |
| Cost for Generation is less |
What is the ideal cycle for steam power plants?
The Rankine cycle
The Rankine cycle is the ideal cycle for vapor power plants; it includes the following four reversible processes: 1-2: Isentropic compression Water enters the pump as state 1 as saturated liquid and is compressed isentropically to the operating pressure of the boiler.
What cycle is used in power plants?
The Rankine cycle or Rankine Vapor Cycle is the process widely used by power plants such as coal-fired power plants or nuclear reactors. In this mechanism, a fuel is used to produce heat within a boiler, converting water into steam which then expands through a turbine producing useful work.
