AIR POLLUTANTS SMELTING FURNACE: Hot SAF off gas emissions contain dust particulates, Sulphur dioxide, oxides of nitrogen, carbon monoxide and traces of oxides of silica FINISHED PRODUCT SIZING & PREPARATION: The cast product would be cooled, ground and screened for final bagging. Such operation would generate fugitive dust . BOILER EMISSION : The flue gases from the boiler exhausted into the atmosphere carry with them considerable quantities quantities of pollutants pollutants such as SPM, SO2, NOx, CO etc. Followi













AIR POLLUTION MANAGEMENT SMELTING FURNACE: Hot off gases from submerged arc furnace (SAF) and tap hole secondary emissions laden with fine product dust would be cooled to 150-250oC by air dilution prior to passing it it through fume fume extraction system. The exit gases would be cleaned by dry gas de-dusting system.

Bag filters are provided

to remove fine particulate matter will settle in the settling chamber. Resultant clean gas will be vented out to atmosphere at appropriate height. FINISHED PRODUCT SIZING & PREPARATION: Significant amount of fugitive emission mainly in form of dust will be













Cont. For open yard operation, provision will be made to spray water to reduce the dust generation during handling operation. BOILER & DG SET EMISSION : Electro Static Precipitator (ESP) will be provided to control dust emission from the boiler. Further low sulphur content coal will be used to reduce SO2 generation. The flue gas will be dispersed into the atmosphere through a

GAUSSIAN PLUME DISPERSION MODEL The dispersion of pollutants in the atmosphere is determined using Gaussian plume dispersion model. For the present study, this model is used for the prediction of maximum ground level concentration (GLC). The different air emissions from the unit are PM, SO2, NOx and CO from













OTHER MEASURES



Regular ambient air quality monitoring should be carried out within premises and nearby area for PM, RSPM, SO2, NOX and CO.













FLY ASH MANAGEMENT Ash generated during the operation of power plant will be suitably collected and disposed off. A system for collection and commercial disposal of this this waste product product to end users’ works will be planned. Ash













THERMAL POLLUTION MANAGEMENT All equipments and pipelines whose surface temperature is 50 0C and above will be provided with thermal insulation.













NOISE MANAGEMENT The plant and equipment will be specified and designed with a view to minimise noise pollution. The major noise producing producing equipment such as turbogenerator, pumps, fans, compressors etc will be provided with
