Dear Debasree Banerjee ,

I think one has to determine at first how may cubic meters are produced in burning fuel to produce one kwh.

Then we multiply the particulate density ug/ m^3 times the cubic meters produced for one kwh.

This can be obtained from the analysis of the burning process.

Best wishes

Dear Debasree,

I think, conversion efficiency is needed to calculate this.

You see that the dimension of μg/m³

and g/ kWh are different.

So you need the conversion efficiency.

Thanks
