Diesel Power Plant

  1. 1. NAME MATRIX NO. MUHAMAD RIZAL BIN SHABAATH ALI 16DKM10F1017 MUHAMMAD ARIFF BIN YUSOF 16DKM10F1011 MUHAMMAD SHAFIQ BIN JAMALUDDIN 16DKM10F1018 DIESEL POWER PLANT JJ618-PLANT ENGINEERING
  2. 2.  They are used as central station for small or medium power supplies.  They can be used as stand-by plants to hydro-electric power plants and steam power plants for emergency services.  They can be used as peak load plants in combinations with thermal or hydro-plants.  They are quite suitable for mobile power generation and are widely used in transportation systems such as automobiles, railways, air planes and ships.  Now-a-days power cut has become a regular feature for industries. The only solution to tide over this difficulty is to install diesel generating sets. APPLICATIONS OF DIESEL POWER PLANT
  3. 3. DIESEL ENGINE POWER PLANT
  4. 4. LAYOUT OF DIESEL POWER PLANT
  5. 5. GENERAL LAYOUT
  6. 6. SIMPLE LAYOUT
  7. 7. Engine System Starting System Lubrication System Fuel System Air filter and Supercharge Cooling System Exhaust System Governing System MAJOR SYSTEM IN DIESEL POWER PLANT
  8. 8.  Generally classified as two stroke engine and four stroke engines.  In diesel engine, air admitted into the cylinder is compressed  At the end of compression stroke, fuel is injected.  It burns and the burning gases expand and do work on the position.  The gases are then exhausted from the cylinder to atmosphere. ENGINE SYSTEM
  9. 9. This includes air compressor and starting air tank. The function of this system is to start the engine from cold by supplying compressed air. STARTING SYSTEM
  10. 10. It includes the oil pumps, oil tanks, filters, coolers and connecting pipes. The purpose of the lubrication system is to reduce the wear of the engine moving parts Part of the cylinder such as piston , shafts , valves must be lubricated It is cooled before recirculation. Lubrication also helps to cool the engine LUBRICATION SYSTEM
  11. 11. OIL TANK
  12. 12.  It includes the storage tank, fuel pump, fuel transfer pump, strainers and heater.  Pump draws diesel from storage tank to day tank through the filter  The day tank is usually placed high so that diesel flows to engine under gravity.  Diesel is filtered before being injected into the engine by the fuel injection pump. strainers FUEL SYSTEM
  13. 13. Air filter is used to remove the dust from the air which is taken by the engine. The supercharger is used to increase the pressure of the air supplied. AIR FILTER AND SUPERCHARGE
  14. 14. This system includes water circulating pumps, cooling towers or spray ponds and water filtration Use to carry the heat from the engine cylinder(maintain temperature level) Water is circulated inside the engine in water jackets Passage around the cylinder, piston, combustion chamber Hot water leaving the jacket is sent to heat exchanger. It is cooled in the cooling tower and recirculates again. COOLING SYSTEM
  15. 15. COOLING TOWER
  16. 16. This includes the silencers and connecting ducts. The exhaust gases coming out of the engine is very noisy. silencer (muffler) is provide to reduce the noise. EXHAUST SYSTEM
  17. 17. The function of the governing system is to maintain the speed of the engine This is done generally by varying fuel supply to the engine according to load. GOVERNING SYSTEM
  18. 18. DISADVANTAGES  High running charges due to costly price of Diesel  Generates small amount of power  Cost of lubrication very high  Maintenance charges are generally high ADVANTAGES AND DISADVANTAGES OF DIESEL POWER PLANT ADVANTAGE  Simple design & layout of plant  Occupies less space & is compact  Can be started quickly and picks up load in a short time  Requires less water for cooling  Thermal efficiency better that of Steam Power Plant of same size  Overall cost is cheaper than that of Steam Power Plant of same size
