INDUSTRIAL VISIT TO JINDAL URBAN WASTE MANAGEMENT” VISAKHApatnam LIMITED

Event type                   : Industrial Visit of B. Tech-VII Semester STUDENTS

Date /duration             : 12.07.2024 for one day (10am to 12.30pm)

Name of the industry   : Jindal Urban Waste Management (Visakhapatnam) Limited

Faculty accompanied   : Mr. P. Surya, Mr.S.Durga Prasad, and Mr. Ganapathi

Total no of students     : 36

Objective of the event  :To get exposure to the power production and distribution process in Urban Waste-to-    Energy from Municipal Solid Urban Wastes

Outcomes of the event :Students acquired knowledge of power production and distribution process in Municipal Solid Urban Wastes based power plant and observed the working of Water treatment plant, Municipal Solid Urban Wastes handling equipment’s, Boilers, super heaters, Economisers, Condensers, Generators, ash handing equipment’s Cooling tower etc.

Description / Report on Event:

The IVB. TechI Semester A Section Students of Mechanical Engineering accompanied with Two Faculty members visited Jindal Urban Waste Management (Visakapatnam) Limited dated 12.07.2024. The main objective of the visit is to bridge the gap between industry and academia. This power plant is one of the Urban Waste-based power plants of APEPDCL. It is well placed between Visakhapatnam and Kapulupadda village.

After arriving the engineers of Jindal, Visakhapatnam (Mr.Satish and Mr.Bhaskar Reddy) explained about the power plant overview and the working of boilers, Steam Turbine, Economiser, Urban Waste handling equipment.

Followed by session plant visit, Students and faculty moved with the guides were explained about the JUWMVL introduction & Safety precautions. Under the guides supervision the students first visited the Urban Waste bunkers where the Urban Waste unloaded from wagons into the pit, next visited Urban Waste treatment plant, Boilers working, Economisers, cooing tower and power distribution room, generator and turbine room etc.

JUWMVL Visakhapatnam consists of two boilers, turbine and generator and power generation capacity of the plant is 15MW.

PLANT  LOCATION DETAILS:

 The location of the proposed WTE facility– Kapulupadda in Visakhapatnam District, 17 Kms from Visakhapatnam. The geographical location is approximately at 17.844432⁰ E Latitude and 83.366433⁰ N Longitude. The site elevation is 59 m from Mean Sea Level. Soil at the location is rocky and gravel. There is no habitation within the proposed project site.

PROJECT BACKGROUND:

Government of Andhra Pradesh (Govt.AP), as part of Swachh Andhra Mission, proposes to set up Urban Waste to Energy (WTE ) Plants at various locations in Andhra Pradesh and has identified beneficiary Urban Local Bodies (participating ULBs) at each of these locations in Andhra Pradesh which are expected to deliver MSW to the WTE processing facilities.

 New and Renewable Energy Development Corporation of Andhra Pradesh Limited (NREDCAP) was authorized by the participating Urban Local Bodies (ULBs) to run the bidding process for selection of an entity to which the projects in each of the clusters may be awarded. The project was awarded for capacity of 15 MW for Visakhapatnam at a power sale tariff of 6.165/unit. JUWMVL formed project special purpose vehicle (SPV) – Jindal Urban Waste Management (Visakhapatnam) Limited for undertaking the proposed project development, operation and maintenance.

Salient Features of JUWMGL:

Tonnage per day                           Greater Visakhapatnam Municipal Corporation (GVMC) and other 8 ULBs: 1200 MT

Source of Water                                  Treated STP Water

Total Land Area of Existing Plot         17.08 acres for WtE facilities and about 39.85 acres for scientific landfill

Power Connectivity                             Grid Sub-station of APEPDCL at Sitammadara, 3 km

 MSW Handling Capacity                    1650 TPD

Power Generation                                15 MW

Technology used                                  Refuse Derived Fuel (RDF) based power plant

Material Recovery Facility:

• Bio Drying Section – There will be two dumping pits and 12 pits for bio-drying arranged in two bays in a closed shed.
• Material Segregation – after a stipulated period, semi decomposed material will be fed to hopper for manual segregation to remove bigger materials like boulders, stones, synthetic fabrics, mats, tyres, hard boards, woods etc., to facilitate for the pre-processing unit to segregate the Urban Waste effectively. Manual segregation will be followed bymechanical segregation.
• Production of RDF – Drag conveyor will receive material from rake carrier and distribute the same in the designated storage area for further curing. Prepared RDF will be stored in the RDF storage area.
• Main equipment of MRF is belt conveyor, rotary screen trommel, ballistic separator, magnetic separator, shredder, rake carrier, drag conveyor, hopper, de-stoner & cyclone separator, bagging machine, crane, grab bucket etc.

Power Plant:

• Boiler including auxiliaries– Two number of boilers.
• Air pollution control system– Semi wet type of system is being installed at JUWMGL for air pollution control
• Ash handling and Disposal– For disposal of fly ash and bottom ash
• Turbo generator – 1X15 MW
• Condensing plant– Air cooled condenser

Balance of Plant:

• Water system – Treated water from STP will be used at JUWMGL. Total requirement of water for the project is estimated as 324 m3/day as per water balance.
• Compressed air system – for ash handling system and for instrumentation
• Electrical system – including control & instrumentation system
• Heat Ventilation and Air Conditioning (HVAC) – At various plant facilities
• Firefighting – Including hydrant system, spray water system, high velocity water spray system, medium velocity water spray system, hand appliances system, sprinkler system
• Effluent treatment – system for treating discharge from drain from cooling tower, reject & back wash from water treatment section and leachate treatment
• Environment monitoring system – Continuous Emission Monitoring System (CEMS) at stack
• Sanitary Landfill – For disposal of Urban Waste from the MSW processing facility.

Water Supply – Visakhapatnam Municipal Corporation has granted assurance for 500 KLD sewage treated water supply to JUWMVL plant from nearest sewage treatment plant at Etukur.

Ground Water –Water Department has granted permission to JUWMVL for drawing water from four bore wells at sub-project location.

Feedback / Suggestions: The students felt very happy and they expressed that they have learnt a lot about the power production process from Urban Waste based Thermal power plant and observed the process of different thermal devices Boilers, condensers, cooling towers and chimney etc.
