3 INTRODUCTION In hydroelectric power station kinetic energy of stored water is converted into electric energy 30% of the total power in world is provided by hydro power plant The world s hydro power potential is about 2724 MkW Total hydro power potential of India is 84 MkW and 22% of this potential is being tapped by various existing and ongoing power
Diesel power plants use diesel engines connected to electric generators to produce electricity The diesel engine acts as a prime mover converting the chemical energy in diesel fuel into mechanical energy used to rotate the generator and produce electrical energy Key components include the diesel engine fuel supply system air intake system exhaust system
The advantages of diesel power plants are listed below 1 Diesel power plant design is simple for installation 2 The layout of the diesel power plant is quite simple 3 The limited quantity of cooling water required 4 Standby losses are very less as compared to other Power plants 5 Low fuel cost for operation 6
The Role of Thermal Power Plant in the Modern Power Generation Scenario The development of thermal power plant in any country depends upon the available resources in that country The hydro power plant totally depends on the natural availability of the site and the hydrological cycle The new sites cannot be created manually for hydropower plants
A power plant can be of several types depending mainly on the type of fuel used A power generating station can be broadly classified in to 5 types mentioned below Thermal Power Plants Diesel Engine Power Plants Gas Turbine Power Plants Nuclear Power Plants Hydro Electric Power Plants
1 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 ii They are used as standby sets for continuity of supply such as hospitals telephone exchanges radio stations cinema theatres and industries
A diesel power plant uses a diesel engine as the prime mover to generate electricity It typically generates 2 50 MW of power The main components are the diesel engine air intake system fuel supply system exhaust system cooling system lubricating system and starting system
The oil engines and gas engines are called Internal Combustion Engines In IC engines fuels burn inside the engine and the products of combustion f ro m the
13 Solar collectors capture and concentrate sunlight to heat a synthetic oil called terminal which then heats water to create steam The steam is piped to an onsite turbine generator to produce electricity which is then transmitted over power lines On cloudy days the plant has a supplementary natural gas boiler The plant can burn natural gas to heat the water
Gas turbine power plant… 4 November 2010 Advantages of gas turbine power plant Storage of fuel requires less area and handling is easy The cost of maintenance is less It is simple in construction There is no need for boiler condenser and other accessories as in the case of steam power plants
8 Nuclear Atomic Power Plant… Nuclear fission… U235 splits into two fragments Ba141 & K92 of approximately equal size About neutrons are released 1 neutron is used to sustain the chain reaction neutrons is absorbed by U238 and becomes Pu239 The remaining neutrons escapes from the reactor The neutrons produced move at a very
6 Layout of a Diesel power plant… 20 April 2017 Layout of a Diesel power plant… 3 Fuel supply system Fuel from the storage tank is pumped through a filter into a smaller tank called all day tank This tank supplies the daily requirements of the diesel engine The all day tank is placed high so that the fuel flows to the engine under gravity with sufficient pressure
Ppt for power plant Download as a PDF or view online for free Layout of hydro electric power plant 95 Hydro power plant 101 UNIT 3 NUCLEAR POWER PLANT 102 Layout of nuclear power plant 113 Inside a Nuclear
Diesel power plant Free download as Powerpoint Presentation ppt PDF File pdf Text File txt or view presentation slides online The document discusses the key aspects of diesel power plants and a lifespan of only 2 5 years It then covers the major components of diesel power plants including the diesel engine starting system
8 Coal and Ash handling plant Coal is transported to power station by rail or road and stored in coal storage plant and then pulverised Pulverised coal is fed to fed to the boiler by belt conveyers Coal gets burned in the boiler and ash produced is removed to the ash handling plant and then delivered to ash storage plant for disposal A 100MW station operating at 50%
Layout of Components The diesel engine power plant is an assemble of the diesel engine coupled to a generator and various auxiliary parts and systems This is demonstrated in figure 3 Figure 2 Components of a diesel power plant From figure 3 it is observed that the main elements of a diesel power plant are the engine prime mover the
