DM Plant Block Diagram GENERAL TURBINE DATA (KWU) Bottom Ash The ash which is directly collected from bottom of boiler is called bottom ash. Dry Ash Handling System If fly ash is discharge in atmosphere, it will create heavy air pollution thereby resulting health hazards. Hence it is necessary to precipitate ash from flue gases.
Coal Handling Plant, Ash Handling Plant, Cooling towers, Units 1 to 4 and PTPS2 comprising of 210MW /250MW Units 5 to 8. Working of Thermal Power Plant can be explained with the help of a block diagram .
At 5 seconds before time out, the boiler control system closes the pilot block valves and opens the pilot vent valve. The remaining 5 seconds are used to detect the main flame. For the typical dual flame scanner design, a main flame failure shutdown is initiated if both flame scanners return a no flame signal to the burner control system.
May 07, 2014#0183;#32;Bottom Ash Handling System Bottom ash resulting from the combustion of coal in the boiler falls into the over ground, refractory lined, water impounded, maintained level, double VSection type/ W type steel fabricated bottom ash hopper having a hold up volume to store bottom ash and economizer ash of maximum allowable condition with the rate
May 07, 2014 #183; Requirement of Ash Handling System In Thermal Power Plants 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.

Feb 25, 2016#0183;#32;Bottom ash handling System. The bottom ash quantity is around 20% of the total Ash generation and there are mainly two types of bottom ash disposal systems. Dry Type Bottom Ash Disposal; Wet Ash Slurry Disposal; Dry Type Bottom Ash Disposal: First of all we will discuss about the Dry type bottom ash disposal system.
After complete combustion of coal, ash is delivered to the ash storage plant by scrap conveyors for disposal. Generally, it is seen that a 100 MW power plant which operates 10% to 12% load factor may burn 20,000 tons of coal per month and ash is produced nearly 2000 to 3000 tons per block diagram of thermal power plant is shown in
