Starting of the diesel engine includes the air tanks along with the air compressor. of moving parts and reduce the wear and tear of the engine parts. They require less cooling water . Air filter and supercharger 3. Required fields are marked *. 2. Diesel engines have some disadvantages: They are noisy, polluting, driven economically by fuel costs (and thus captive to world politics), require fuel storage close to the power plant, and require logistics and infrastructure for transportation. (v) Diesel power plants are becoming more popular because of difficulties experienced in construction of new hydel plants and thermal plants, The essential components of diesel power plant are, • Diesel engine • Air filter and super charger • Engine starting system • Fuel system • Lubrication system • Cooling system • Governing system • Exhaust system. The function of this system is to start the engine from the cold by supplying the compressed air. The fuel injection system performs the following functions. Capacity is restricted. Diesel engine sart ting systems After reading this chapter, the student should be able to: 1. The air intake supplies the air to the engine for subsequent operations. The function of the air filter is to remove the dust from the air which is taken by the engine. Diesel electric plants in the range of 2 to 50 MW capacities are used as central stations for small electric supply networks and used as a standby to hydroelectric or thermal plants where continuous power supply is needed. It is worth taking a few time to read it. Diesel generators are covered by a wide range of federal, state and local requirements regarding emissions performance and operating conditions. The fuel oil may be supplied at the plant site by trucks, road, rail, tank etc. This raises the possibility that power plant developers will continue to follow the pattern of the 1990s and rely heavily on natural gas plants to meet the need for new power generation.! Requires less quantity of water for cooling purpose. They can be easily started or stopped at a short notice to meet the peak demand. After the combustion, the burned gases are exhausted to the atmosphere. 12. 1. The engine is started from cold condition whit the help of an air compressor. Diesel electric plants can be used as central station where the capacity required is small, Advantages and disadvantages of diesel power plant, Following are the advantages of diesel power plant. These include: meeting peak power demands by having generating sets which can be started and brought in quickly; having a reliable self-starting power source to restart other Diesel is converted into electrical energy. Federal regulations governing the hours of operation are different for emergency and non-emergency uses. In oil bath type of filters, the air is swept over a bath of oil so that dust particles get coated. Diesel Power Plant. Identify all main components of an electric starter … 6. Lubrication oil which gets heated due to the friction of the moving parts is cooled before re-circulation. Schematic diesel engine power plant 17. link to Hydraulic seals - Definition, Types, Diagram , Function, Failure, Application, link to Slotter Machine - Types, Parts, Operations, Diagram, Specification. Generally, two-stroke engines are used for diesel power plants. It is easy to design and install these electric stations. 5. (e) Nursery station: In the absence of main grid, a diesel plant can be installed to supply power in a small town. Thank you For Visiting. Fuel system. Lubrication system It includes oil pumps, oil tanks, coolers and pipes. For starting the engine initially, the various things used are compressed air, battery, a self-starter or electric motor. Your email address will not be published. The water envelopes (water jacket) the engine, the heat from the cylinder, piston, combustion chamber etc, is carried by the circulating water. Today diesel engines are the backbone of any industry. Quick starting and easy pick-up of loads are possible in a very short time. Very simple design also simple installation and occupies less space. 10. Unlike a gasoline engine, a diesel engine does not require an ignition system because in a diesel engine the fuel is injected into the cylinder as the piston comes to the top of its compression stroke. 4.4.6 Performance Testing of Diesel Engine Power Plant 4.5 Summary 4.6 Answers to SAQs 4.1 INTRODUCTION 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. This includes the silencers and connecting ducts. Noise problem. The layout of a diesel power plant is shown in the figure. Working of Diesel Power Plant The air and fuel mixture act as a working medium in diesel engine power plant. Engines are generally directly coupled to the generator for developing power. 7. 3. 13. (vi) Engine starting system: This is an arrangement to rotate the engine initially while starting until firing starts and the unit runs with its own power. There are less standby losses. Exhaust system 4. He also likes to write articles related to the mechanical engineering field and tries to motivate other mechanical engineering students by his innovative project ideas, design, models and videos. The diesel engines are generally classified into four strokes and two-stroke engines. 1. If What you looking for is not here, you may send a request to modify articles, Notes, and Content modification, Feedback, Suggestions here (Team will reply as early as Possible ): Important fuel specifications for Diesel Used In IC Engine. The use of the supercharger is to increase the pressure of the air provided to the engine to increase the power of the engine. Small sets are started manually by handles but for larger units, compressed air is used for starting. Compressed air is used for starting. system of diesel electric power plant. The diesel burns Why Diesel engines are Not used in Motor Bikes or Mopeds . Efficiency at part loads is also higher . 15. This site uses Akismet to reduce spam. diesel plant can be installed to supply power to villages. 11. This system consists of a fuel tank for the storage of fuel, fuel filters and pumps to transfer and inject the fuel. (c) Standby unit: If the main unit fails or cannot cope up with the demand, a diesel plant can supply the necessary power. connecting pipes. He completed his engineering studies in 2014 and is currently working in a large firm as Mechanical Engineer. 4. It is used to reduce the friction of moving parts and reduce wear and tear of the engine parts such as cylinder walls and piston. High efficiency of energy conversion from fuel to electricity. 2. It includes oil pumps, oil tanks, filters, coolers and Have any question tell us in the comments. Types of Wind Turbine Diesel engines … These plants can be located very nearer to the load centres. The hot water leaving the jacket is passed through the heat exchanger. (d) Emergency 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. High operating cost. Starting system 8. This liberates the huge amount of energy which is utilized to run the generator to produce the electric power. Thank you For Visiting. The plant is powered by 38 Wärtsilä 50DF multi-fuel engines with a combined capacity of 573 MW. Disadvantages in in stalling diesel units for power generation . Diesel engines have found their application in every field of electricity generation, water pumping etc. It may be considered as a vertical shaper. This is used to start the engine in cold conditions by supplying the air. These can be used as a standby unit to supply part load. The power plant produces a total output of 88 MW. Cooling system The temperature of the burning fuel inside the engine cylinder is in the order of 1500 0 C to 2000 0 C. In order to lower this temperature, water is circulated around the engine. Air filters may be of dry type, which is made up of felt, wool or cloth. 3. He is also an author and editor at theengineerspost.com. This consists of the governor and its function is to maintain the speed of the engine constant irrespective of load on the plant by controlling the fuel supply to the engine according to the load.
