Emission of flue gases from industrial boilers and generators and their control

Analysis of flue gases in the Stacks was carried out for 17 gas-fired boilers and 19 gas/diesel-fired generators and the concentrations of CO, NO/sub 2/, NO/sub x/ NO/sub 2/ SO/sub 2/ and C/sub x/ H/sub y/ were studied in the stack- emissions. The results have then been discussed with reference to the permissible limits, as per National Environmental Quality Standard. Higher concentration of co was observed in some boilers, and of CO and NO/sub x/ in some generators. Some effects of major air-pollutants have also been discussed as regards the human health, vegetables and materials. Some remedial measures have also been discussed to limit the concentration of air pollutants emitted from boilers and generators. (author)
