Power Plant Engineering

UNIT-3 HYDRO ELECTRIC POWER PLANT : Water power – hydro-logical cycle / flow measurement – drainage area characteristics - hydro graphs - storage and pondage - classification of dams and spill ways. HYDRO PROJECTS AND PLANT : Classification – typical layouts – plant auxiliaries – plant operation pumped storage plants. Introduction to Water Power : Hydro power or water power (from Greek) is power derived from the energy of falling water or fast running water, which may be harnessed for useful purposes. Since ancient times, hydro power from many kinds of watermills has been used as a renewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills, trip hammers, dock cranes, domestic lifts, and ore mills. A tromp, which produces compressed air from falling water, is sometimes used to power other machinery at a distance. Hydro Cycle / Water Cycle / Hydro-logical Cycle : The sun, which drives the w...

UNIT – 2 INTERNAL COMBUSTION AND GAS TURBINE POWER PLANTS :  DIESEL POWER PLANT : Plant layout with auxiliaries – fuel supply system, air starting equipment, super charging. GAS TURBINE PLANT : Introduction,classification-construction layout with auxiliaries,combined cycle power plants and comparison. Diesel Power Plant Layout : Applications of diesel power plant: Diesel power plant is in the range of 2 to 50 MW capacity. 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 o...
