Figure 4 Schematic flow diagram of coal handling system 6 Reliability Analysis of Coal Handling System Step 1 Information collection The repair and failure data for each subsystem component are taken from the CHS maintenance log book which were checked by maintenance expert and are presented in table1 Table 1 Repair and failure data for CHS
5 Coal from the coal wagons is unloaded by Tipplers in the coal handling plant This coal is transported up to the coal storage bunkers through conveyor belts Coal is then transported to the Crush house by conveyor belts where it is crushed to small pieces and light dust is separated The crushed coal is then transported to the bowl mill by coal
The design of the material handling system is an important component of the facilities design problem There exists a strong relationship between the layout design and the material handling design function In a typical factory handling accounts for 25% of all employees 55% of all factory space and 87% of production time Material handling

1 Belt Conveyor Belt Conveyor merupakan salah satu peralatan utama coal handling system yang berfungsi untuk mendistribusikan mengangkut batu bara mulai dari unloading area Intake Hopper sampai Coal Bunker power plant
Coal storage in stockpiles is essential in ensuring continuous supply of feedstock for large capacity power units Because of the tendency of coal to self heat followed by spontaneous ignition and spontaneous combustion there are cautions that need to be observed and stockpiling sometimes referred to as stacking of coal has to be done consciously and by
1 Coal handling storage of coal • The main purpose of storage of coal is • To store the coal for a period of 30 to 90 days therefore the plant is not required to be shut down due to failure of normal supply of coal • To permit the choice of the date of purchase allowing the management to take advantage of seasonal market conditions in prices of coal
1 Planning principle All handling activities should be planned 2 Systems principle Plan a system integrating as many handling activities as possible and co ordinating the full scope of operations receiving storage production inspection packing warehousing supply and transportation 3

For example the dust in their coal handling system exceeded the standard level and a large amount of dust is produced in the coal unloading coal handling coal loading and other processes [1] Since the falling coal dust cannot be cleaned in time during continuous work the coal dust is suspended in the air for a long time which
The function of Mill Reject Handling system MRHS is to automatically discharge the iron pyrite and other non‐grind‐able material from coal mill through an outlet connection to the reject conveying system Basic Working of Mill Reject Handling System MRHS
The basic systems are 1 Coal Handling System Coal is crushed fed into a pulverizer and blown into the boiler where it is combusted 2 Post Combustion Clean up System SO 2 particulate and ash are removed before exhaust products are sent via the stack to the environment 3
COAL BASED POWER PLANT Coal needs to be stored at various stages of the preparation process and conveyed around the CPP facilities Coal handling is part of the larger field of bulk material handling and is a complex Ash Handling Systems is the none / un combusted portion or residue after taking combustion of any solid fuel Solid fuel
A coal handling system equipment is a bulk material handling system; it plays an important role in key mechanical industries It holds the important aspects of a country economy in mining smelter plants thermal power plants process industries etc Considering operation attributes of the coal handling belt conveyors various parameters have to be taken into
However in the power plant still there is need to transport the coall from mines unload it coal movement through conveyors crushing it and sending it to boiler The main sub systems of the coal handling plant are wagon tipplers Belt conveyors Coal Crushers and drive units The coal is received by railways or large trucks from mines
state of Johor Malaysia is one of the largest coal fired power plants in Asia The contract for the design manufacture supply erection and commissioning of the coal handling system was awarded to TKF The coal handling system comprises the following major parts • Two continuous ship unloaders of chain bucket elevator type;
In addition to equipment specifications P&ID diagrams and basic PLC programming needs are specified Also acceptance test criteria for the systems will be defined for bias tests sampling ratio tests and other acceptance tests All of the tailor made equipment and machines in this coal handling system will be supplied by TKIIL and TKRT
