Mar 19, 2018· A thermal power generating plant works based on Rankine Cycle. There are mainly three primary inputs given to a thermal power generating plants for producing electricity. These three most essential elements are coal, air, and water. Coal is fuel here because we are going to draw the flow diagram .
The thermal plant would cause smoke, noise steam, water vapors and so on so we shouldn''t build it near to dense locality. We should care to have ample scope of development of the future demand. There would also be a very near place for ash handling plant. Types of thermal power generation: Steam power generation plant:
Ash handling systems may employ pneumatic ash conveying or mechanical ash conveyors. A typical pneumatic ash handling system will employ vacuum pneumatic ash collection and ash conveying from several ash pick up stationswith delivery to an ash storage silo .
Secondly, Indian coal has high ash content (40 to 50%) which is also highly abrasive in nature. As a result, domestic coal based power plant is likely to produce 3 to 5 times more ash than that based on imported coal. The above aspects need special skills to design large capacity ash handling systems for using Indian coal.
Jun 08, 2018· Fuel storage and handling plant. The most essential part of any power plant is to store the fuel safely in an appropriate amount so that the plant can run smoothly in normal days as well as when the supply of fuel from mines is improper. So a fuel storage facility is defined in a plant to store an adequate amount of fuel.
May 07, 2014· Requirement of Ash Handling System In Thermal Power Plant''s coal is generally used as fuel and hence the ash is produced as the byproduct of Combustion. Ash generated in power plant is about 30 40% of total coal consumption and hence the system is required to handle Ash for its proper utilization or disposal.
