To Generate 210 MW
Electricity approximately
3200 -3500MT Coal is
daily required.
If 40% of Ash contents
is considered then
1280 -1400 MT Ash is
produced every day from
one 210 MW set.

To Dispose such huge
quantity of Ash we required
a huge Ash Handling System.
This system is called
Ash Handling Plant.

In ESP there is DC field is created
which is of 60 KV.Where plates &
electrodes are vertically fitted. Due
to this field Ionization is happened &
Flue gas particles are charged by
+ve & -ve charged. Ash particles are
collected on plates & gas particles go
out through the Chimney.
