Introduction to Coal handling plant. In a coal based thermal power plant, the initial process in the power generation is "Coal Handling".So in this article i will discuss the overall processes carried out at a Coal Handling plant in a coal based thermal power generating station.
Coal handling systems are an integral part of a complete material flow and quality management system (Figure 1). In recent years, the main focus was on the optimisation of single parts of this system, such as mine planning or advanced automation solutions. Now, however, complete system optimisation, including the integration of all subsystems, is

Advantages of this system Low power consumption as water is not moved, only ash. Heat can be recovered from hot ash and resent to boiler, thereby increasing boiler efficiency. This is not possible in wet systems ... Microsoft PowerPoint - BOTTOM ASH & FLY ASH HANDLING SYSTEMS
Sep 30, 2018· Ash handling plant or ash handling system in thermal power plant are used to cooled down the ash to manageable temperature, transferred to a disposal area or storage which is further utilized in other industries.
The direct cost of electric energy produced by a thermal power station is the result of cost of fuel, capital cost for the plant, operator labour, maintenance, and such factors as ash handling and disposal.
The ash handling technology is divided into two-the bottom ash handling and fly ash handling. Of the bottom ash handling system, the Magaldi Ash Cooler System (MAC System) developed by Italy's Magaldi, Inc. is a mechanical handling system requiring no cooling water uses air to cool bottom ash, contributing greatly to the drastic simplification of facilities and the effective use of heat.
This system is suitable, where coal is to be transferred over shorter distance and space limitations exist. The initial cost of the system is low. It suffers from the drawbacks that the power consumption is high and there is considerablewearofscrew. Rotation of screw varies between 75-125 R.P.M.
Nov 13, 2016· The initial process in coal based thermal power plant is coal handling.The Function of coal Handling Plant in thermal power plant is to receive, process, store, feed the coal bunkers consistently over entire life of the power plant. Coal is transported in thermal power station either by railways,roadways or rope ways.

Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse.
This brief overview on steam power plants focuses on conventional pulverized coal fired power plants (PCF PP). While the steam cycle section of the power plant is similar for power plants operated on all fuels, the fuel handling, combustion and post-combustion environmental control systems are substantially more complex in PCF PP.
Pneumatic conveying systems to transport fly ash in dry mode are extensively used in coal fired thermal power plants in India in large capacities due to the high ash content of Indian coal and the increasing requirements of conveying fly ash in dry form. However, reliable design of such
