Why diesel power plant are not used for high capacity?
For generating electrical power, it is essential to rotate the rotor of an alternator by means of a prime mover. The mechanical power required for driving alternator comes from combustion of diesel. As the diesel costs high, this type of power station is not suitable for producing power in large scale in our country.
What is the disadvantage of diesel power plant?
Disadvantages of Diesel Power Plant/Station The plant has high running charges as the fuel (i.e., diesel) used is costly. The plant can only generate small power. The maintenance charges are generally high. The plant does not work satisfactorily under overload conditions for a longer period.
What is the capacity of diesel power plant?
NEW DELHI: The total capacity of diesel generators in India is estimated at 72 gigawatts, about 25\% of the installed capacity of power plants, and growing at the rate of 5 GW a year, the Economic Survey said. The total installed capacity of thermal, hydro and renewable power plants in the country is 288 GW.
What are the advantages and disadvantages of a diesel power plant?
Operation
| Advantages | Disadvantages |
|---|---|
| Requires less water for cooling | Cost of lubrication very high |
| Thermal efficiency better that of Steam Power plant of same size | Maintenance charges are generally high |
| Overall cost is cheaper than that of Steam Power plant of same size | . |
| Requires no Operating staff | . |
Which of the following is a advantage of diesel power plant?
The advantages of diesel power plants are listed below: Standby losses are very less as compared to other Power plants. Low fuel cost for operation. Smaller storage is needed for the fuel.
Where are diesel power plants commonly used?
Coal, Natural Gas, Oil and Nuclear Generation Diesel generators are widely used at most Coal, Gas and Oil Fired Power Plants and virtually all Nuclear Power Plants in the United States has an emergency backup power source for the station’s auxiliary needs.
Why diesel power plant is important?
Definition of Diesel Electric Power Plant: A generating station in which diesel engine is used as the prime mover for the generation of electrical energy is known as diesel power station. For generating electrical power, it is essential to rotate the rotor of an alternator by means of a prime mover.
How does a diesel power plant work?
In a diesel power station, diesel engine is used as the prime mover. The diesel burns inside the engine and the products of this combustion act as the working fluid to produce mechanical energy. The diesel engine drives alternator which converts mechanical energy into electrical energy.
What is the function of air intake system of diesel power plant?
Air intake system The air required for the combustion of fuel inside the diesel engine cylinder is drawn through the air filter. The purpose of the filter is to remove dust from the incoming air.
How do diesel power plants work?
How does diesel fuel affect the environment?
Environment – Emissions from diesel engines contribute to the production of ground-level ozone which damages crops, trees and other vegetation. Also produced is acid rain, which affects soil, lakes and streams and enters the human food chain via water, produce, meat and fish.
What are the advantages of diesel electric plant?
During power interruption in a vital unit like a key industrial plant or a hospital, a diesel electric plant can be used to generate the needed power. In the absence of main grid, a diesel plant can be installed to supply power in a small town.
What happens if the main unit of a Diesel Plant fails?
If the main unit fails or cannot cope up with the demand, a diesel plant can supply the necessary power. For example, if water available in a hydro-plant is not adequately available due to less rainfall, the diesel station can operate in parallel to generate the short fall in power.
Is a diesel engine power plant a fossil fuel plant?
This is a fossil fuel plant since diesel is a fossil fuel. Diesel engine power plants are installed where supply of coal and water is not available in sufficient quantity. (i) These plants produce the power in the range of 2 to 50 MW.
How can a diesel plant be installed in a small town?
In the absence of main grid, a diesel plant can be installed to supply power in a small town. In course of time, when electricity from the main grid becomes available in the town, the diesel unit can be shifted to some other area which needs power on a small scale.
