Which boiler is used in thermal power plant?
Normally horizontal return fire tube boiler is used in thermal power plant of low capacity. It consists of a horizontal drum into which there are numbers of horizontal tubes. These tubes are submerged in water.
What are the advantages and disadvantages of thermal power station?
What are the advantages and disadvantages of Thermal Power Plant?
- Making Energy from Thermal Power plants is easy.
- The fuel used (coal) is cheap.
- Thermal Power Plant can be set up anywhere near fuel and water supply.
- It requires less space as compared to the hydroelectric power station.
What are the components of thermal power plant?
Components of Thermal Power Plant & Working Explanation
- Fuel storage and handling plant.
- Water Treatment Plant.
- Steam Boiler.
How much is the efficiency of thermal power plant?
The actual thermal efficiency of a modern thermal power plant usually ranges between 35% and 49%. 2.3 Generator loss Modern generators usually attain an efficiency of around 96%-99%. As shown above, in the three main stages of thermal power generation, most of the energy loss comes from cold source loss.
How does a boiler work in a thermal power plant?
What is boiler? It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.
What is the temperature of boiler in thermal power plant?
Here the steam is superheated to 1,000 °F (540 °C) to prepare it for the turbine. Plants that use gas turbines to heat the water for conversion into steam use boilers known as heat recovery steam generators (HRSG).
What is economizer in thermal power plant?
Economizer: It is also known as a feedwater heater. It is a device in which the waste heat of the flue gases is utilized for heating the feed water.
What are the limitations of thermal power plant?
Following are the disadvantages of thermal power plant: The overall efficiency of the power plant is low. The maintenance cost is expensive. The water requirement for maintaining the temperature of the turbines is too much.
What are the merits of thermal power plant?
Advantages of thermal power plant are: Thermal power station has less initial cost as compared to hydro-electric generating station. It requires less space as compared to the hydro-electric power station. The fuel cost is less as compared to gas. Hung amount of power can be generated by TPS.
