Frequent question: What is diesel electric power plant?

Diesel-powered generators provide the most reliable form of emergency backup power. … The actual system consists of the diesel engine unit and generating system, fuel storage/supply, and electrical switchgear.

How does a diesel power plant work?

The air and fuel mixture act as a working medium in diesel engine power plant. … The basic principle in diesel engine is that, the thermal energy is converted into mechanical energy and this mechanical energy is converted into electrical energy to produce the power by using generator or alternator.

How does a diesel power plant produce electricity?

Diesel generators convert some of the chemical energy, contained by the diesel fuel, to mechanical energy through combustion. This mechanical energy then rotates a crank to produce electricity. Electric charges are induced in the wire by moving it through a magnetic field.

What are the application of diesel electric power plant?

Diesel power plants may be used as standby plants where continuity of power supply is essential such as in hospitals, telephone exchanges, radio stations, cinemas etc.

What is DG working principle?

The functioning principle of a diesel generator is actually based on the law of energy conversion. This law states that the energy can neither be created nor be destroyed but can only be transformed from one form to other. A diesel generator contains an engine that uses diesel for its functioning.

What is the disadvantage of diesel power plant?

The plant has high running charges as the fuel (i.e., diesel) used is costly. The plant does not work satisfactorily under overload conditions for a longer period. The plant can only generate small power.

What are the types of diesel power plant?

Diesel power plants are divided into two main classes: stationary and mobile. Stationary diesel power plants use four-stroke diesel engines (less frequently, two-stroke diesel engines), with power ratings of 110, 220, 330, 440, and 735 kilowatts (kW).

How many kWh is a Litre of diesel?

One litre of diesel fuel (auto) has an energy content of approximately 38 MJ – which approximates to 10 kWh (using a ballpark figure) but the efficiency of conversion into kinetic energy is only about 30% – that is better than petrol which is typically 25% depending on the design.

What is the advantage of diesel power plant?


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 .

What are the components of diesel power plant?

The diesel power plant essentially consists of the following components:

  • Engine.
  • Air filter and supercharger.
  • Exhaust system.
  • Fuel system.
  • Cooling system.
  • Lubricating system.
  • Starting system.
  • Governing system.

Who Needs diesel?

5 Important Industries That Rely On Diesel Delivery

  • Agriculture. Farmers need fuel so they can effectively grow crops which will in turn feed the world. …
  • Mining. Oh boy, if you thought tractors were big you should take a look at mining equipment. …
  • Drilling. …
  • Construction. …
  • Remote Energy.

How many types of DG are there?

The type of DG directly influences the penetration level and the placement of DG. In this study, genetic algorithm (GA) technique is proposed to find the optimum location for three different types of distributed generation, these types are synchronous generator, wind turbine and photovoltaic.

What is DG efficiency?

As a unit of power produced by DG costs 15-20 rupees with a typical efficiency of 30-35%, improving the efficiency of the alternator will result in a significant reduction in diesel consumption per unit produced.

Which coolant is used in DG set?

It is not recommended to add more than 60% antifreeze to the coolant, otherwise it will reduce the antifreeze protection of the diesel generator set. It is recommended to use ethylene glycol as antifreeze.
