07/05/2014· 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.
The balance of plant (BOP) controls for a power plant are defined as the controls outside the main power plant control, such as controls pertinent to offsites like a coal handling plant, ash handling plant, etc. All these auxiliary and offsite plants have been covered in Chapters 2 and Chapter 7, Main Clause 2.5. However, various control

In a coal based thermal power plant, huge amount of ash is generated which has to be disposed off continuously. Typically for a 2x500 MW plant based on Indian coal, the amount of ash generated is around 300 to 400 TPH depending on gross calorific value and ash content of worst coal.
Kawasaki has supplied as many as approximately 80% of the ash handlingplants to Japan's commercial coal-fired power plants by responding to every type of boilers including a pulverized coal boiler, a fluidized bed boiler and a COM (coal-oil mixture) boiler. Features. The ash handling technology is divided into two-the bottom ash handling and fly ash handling. Of the bottom ash handling system

LIST DOWN THE FACTORS TO BE CONSIDERED FOR SELECTION OF SITE FOR THERMAL POWER PLANT: Availability of coal: • A thermal plant of 400M, capacity requires nearly 6000 tons of coal every day. • Power plant should be located near coal mines. Ash Disposal Facilities: • Ash comes out in hot condition and handling is difficult.

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. DESEIN has been responsible for the design & engineering of a large number of Ash Handling Systems for thermal power plants having a total aggregate generating

large capacity power stations being installed in India. A thermal power plant is a complex engineering system comprised of various units: coal handling, steam generation, cooling water, crushing, ash handling, power generation, and feed water. For the regular and economical generation of power, it is necessary to maintain each ash handling
Demerits of thermal power plants . 1. Thermal plant are less efficient than diesel plants . 2. Starting up the plant and bringing into service takes more time. 3. Cooling water required is more. 4. Space required is more . 5. Storage required for the fuel is more . 6. Ash handling is a big problem. 7. Not economical in areas which are remote from coal fields . 8. Fuel transportation, handling

Coal is transported from coal mines to the power plant by railway in wagons or if it a pit head station then by merry go round system. Coal is unloaded from wagon to a moving underground conveyor belt. Coal is either stacked in coal stock yard having about 30 days capacity or is taken to coal crusher house with the help of conveyor belt as per CHP layout.
