Installation and proper working of Fabric Filters, mechanical Dust Collectors and Electrostatic Precipitators can minimize the flying of ash from Chimney. The flying of ash coming out of ash pond can be greatly reduced by sufficient plantation along its dikes, by sprinkling water in it during dry months, by covering the disposal trucks I jumpers by tarpaulin, by now crawler type equipment inside ponds. The emission of Sulphur Dioxide through Chimney stack can be reduced by desulphurisation and by absorption in saline water assign Norway. Both So2 and NO2 can be checked by scrubber system, catalytic systems and primary modifications in combustion process. The emission of CO2 and CO from Chimneys of height above 100 meters is negligible compared to the emission of exhaust grease from automobiles in big cities. The flow of oil spilled over during transfer from rakes to oil base can be reduced by proper care in tightening the bolts in flanges and storing it in a tank or pond with gravity separation of oil water. The oil can be regenerated for use in operation, as there is technical difficulty to sell it.
