18. PROPOSED PROJECT 32 MW CAPTIVE POWER PLANT

19. NEED OF PROJECT The existing Ferro alloy plant had been stopped since last ten years due to unavailability of power. Since the state grid power supply is economically unviable in long run and every effort to restart the ferro alloy plant using power from other sources were unsuccessful, it has decided to install a 32 MW Captive Power Plant to augment the power requirement. The proposed 32 MW captive power plant is coal based with fluidized bed combustion technology. Power from the CPP will be used to run ferro alloy plant and the surplus power will be exported to consumers.

20. PROPOSED PROCESS Fluidized bed combustion type of 140 TPH capacity. Boiler Water requirement of the proposed unit is 418.4 m3/ day and it all will be provided by Tungabhadra dam.

33. 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 of pollutants such as SPM, SO2, NOx, CO etc. Following measures are provided to control flue gas emissions: DG SET : Two DG set will be used as power back up. The flue gas emission from DG sets contains significant proposition of SO2 since HSD will be used as fuel.

34. 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 through 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 envisaged during coal and raw material handling. Dust extraction system will be provided at all material transfer points The dust would be captured by dust extraction (DE) system and taken to a bag filter to separate out the dusts and clean air finally vented through a stack

35. 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 stack of around 60 meter height for effective dispersion of pollutants. DG set are also provided and will be used in case power emergency. Stack of adequate height is provided for effective dispersion of pollutants. For open yard operation, provision will be made to spray water to reduce the dust generation during handling operation.

37. 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 boiler and process vent. Maximum ground level concentration is predicted using dispersion model. The maximum ground level concentration for different parameters is shown in Table 6.3 for proposed scenario. Equal concentration contour plots for the PM, NO2, and SO2 are shown in Figure 6.1 to 6.5 for the proposed scenario. Based on KSPCB limit of pollutants, calculated ground level concentration is superimposed on existing ambient air quality to obtain proposed scenario for the purpose of prediction and evaluation of impact of stack and process emission on surrounding GAUSSIAN PLUME DISPERSION MODEL

39. 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 waste product to end users’ works will be planned. Ash generated in the furnace bed will be periodically removed by means of wet scraper chain conveyor and discharged on to the ash silo meant for wet ash. The fly ash collected from the Economizer, Air Heater and Electro-Static Precipitator will be conveyed to the fly ash silo through mechanical ash handling system. Ash shall be disposed manually or by means of truck from the silos.

40. All equipments and pipelines whose surface temperature is 50 0C and above will be provided with thermal insulation. Further the plant building will be designed for adequate air circulation through natural ventilation. In addition, air conditioning systems will be provided for specific areas. Man coolers will be installed at hot work spots. THERMAL POLLUTION MANAGEMENT

41. The plant and equipment will be specified and designed with a view to minimise noise pollution. The major noise producing equipment such as turbogenerator, pumps, fans, compressors etc will be provided with acoustic enclosures and will run at speeds less than 1500 RPM. Equipment will be statically and dynamically balanced. Safety blow off valves, discharge pipes; relief valves etc. will be equipped with silencers. Pipe lines will be liberally sized for low velocities. Wherever necessary insulation will be provided for reducing heat loss and noise pollution. In effect, the abatement measures will ensure that noise levels are kept below 90 dB (A) at a distance of 1 m from the equipment. NOISE MANAGEMENT

43. The work zone pollution would be mostly due to fugitive dusts, heat and noise. The fugitive dust emission in open area would be controlled by Dust Extraction and Dust Suppression systems as described earlier. As far as possible, natural draft ventilation would be enabled in the shop. All the process vessels would be lined with adequately thick refractory bricks to contain the surface heat emission and in some cases they would be indirectly cooled by water. In addition to this, there would be provision for forced draft cooling and ventilation of closed environment in the work zone. WORK ZONE POLLUTION MANAGEMENT The work zone noise would be mostly emanating from the rotary equipment and machinery like fans, blowers, compressors and pumps. Proper equipment design for control of noise at source, adopting proper protective appliances and administrative control for rotation of manpower in noisy areas would prevent exposure of workmen to high noise levels.

44. Plant safety measures would form an integral part of the environmental management plan of the proposed plant. Workers’ safety would be given highest priority so as to avoid any form of personal injury or lost-time accident. In-built safety features of the plant and machinery would help avoid hazardous events causing damage to the life and property. PLANT SAFETY MANAGEMENT More than 100 trees are present all around existing industry including Fuel storage area , Ash handling system and Administration building etc . There is no tree cut and the area of 10 acre is proposed for tree plantation. The name of the trees will be decided after the discussion with the Local Agricultural Authority and Forest Department. The waste water from the plant after treatment will be used for green belt development (i.e. 12 m3/day ) within the plant premises . GREEN BELT DEVELOPMENT

45. As a part of the Environmental Management Plan (EMP) to be implemented for the Ferro Alloy Plant and Captive Power Plant as a whole, monitoring of air and water quality both at source and in the ambient at the plant site will be done regularly as per Central Pollution Control Board (CPCB) guidelines after the plant is commissioned. For this purpose, appropriate equipment and instruments will be procured along with necessary chemicals, consumables and glassware. To Summarise, the pollution control measures planned for the entire plant will ensure that it will have the least adverse impact on the environment. The adverse impacts of the plant on environment are planned to be prevented by provision of preventive and control systems. POST PROJECT MONITORING
