We have 20 year old BHEL make VU-40 boiler. In this boiler the SO2 in flue gas remains high (Against the permissible limit 100 ppm, it remains 200 ppm due to high sulphur in coal.
Is there any feasible solution keeping in view the high cost, space limitation and ageing of boilers?
A reply will be greatly appreciated.
