A model project of checking environmental threat due to spread of fly ash produced at thermal power stations proved 90-95 percent successful at Shri Singhaji Thermal Power Station, Khandwa. Now, safe disposal of fly ash at thermal power stations will no longer be a big challenge for power generating utilities.

The model for checking spread of fly ash in the environment was prepared and implemented by Tropical Forest Research Institute (TFRI). The project has not been materialised with any big expenditure or installation of plant and machinery, but fly ash is being settled in a natural way to check environment pollution. The project has been successfully implemented by Dr Avinash Jain, Scientist, TFRI, Jabalpur.

Madhya Pradesh Power Generating Company Limited (MPPGCL) implemented the project named ‘Controlling Fugitive Dust Emission from Thermal Power Stations’ at Shri Singhaji Thermal Power Station, Khandwa to check spread of fly ash content in atmosphere through biological reclamations.
Dr Avinash Jain, while talking to ‘The Hitavada’, informed that a study on fly ash disposal was conducted by team of specialists at Shri Singhaji Thermal Power Station for finding better way to check environment pollution. On the basis of study, a project was started to check spread of fly ash in the environment. The model was successfully implemented by MPPGCL at its thermal power station in Khandwa.

The project has been successful in checking environment pollution due to spread of fly ash by 90-95 percent and there is no chance of failure of this project and the same can be implemented at other thermal power stations throughout the country. It may be noted that a thermal power plant generates 1000 tons of fly ash everyday as a solid waste material of coal combustion. Fly ash is usually collected in the electrostatic precipitators (ESP) and disposed off in ash ponds or in the open land and some of these enter into atmosphere by passing through the stacks along with flue gases.
