Waste to Energy Poster

  1. 1. To study and design an innovative municipal solid waste treatment by handling the MSW through incineration process as a new alternative method instead of disposal in landfill and make it as valuable energy resources. Planning, Analysis and Design of a Municipal Incineration System for Bogotá, Colombia Danu Krishana – Diego Puerto – Paula Rodriguez – Nawapol Yamclee Supervisors: Prof. Babbu Alapat École des Mines de Nantes 1. Niessen, W. R. Combustion and Incineration Processes: Applications in Environmental Engineering; M. Dekker: New York, 1978. 2. World Bank, Municipal Solid Incineration, Technical Guidance Report, 1999. 3. Kitto, J. B.; Stultz, S. C. Steam, Its Generation and Use; Babcock & Wilcox: Barberton, OH, 2005. Everyday Bogotá produces around 7,278 Ton of municipal solid waste (MSW); which consists of organic, plastic, paper and inerts. A design of an incineration system for Bogotá was presented by Eternity in this study. It was found that the incineration of the MSW of three areas in Bogotá suitable for incineration and energy generation. With a capacity of 30 Ton/h of MSW and a heating value of 9,6 MJ/kg, 18MW of energy are produced. From the total energy generated, 8MW estimated for internal consumption and the remaining 10MW are sold to the grid. MSW Receiving and Handling 720 Ton /day of MSW with a storage capacity of 8,000 m3 Incineration (1148°C) 2 incineration units fed with 15 Ton of MSW/h per unit Boiler Heat recovery Electricity generation capacity of 18 MW Selective Catalyst Reduction (SCR) Removal of 1073 kg/h of NOx and Dioxins and Furans Electrostatic Precipitator (ESP) Collection of PM by 99.8% (2µm) and 97% (1µm) Venturi Scrubber Acidic gases removal (SOx, HCl) between 70% to 99% By product Handling Production of 24.25 kg of Fly Ash / Ton of MSW and 2.15 kg of Bottom Ash / Ton of MSW Clean GAS Pollutants below the reference values established by Colombian Regulation 1377 of 2015 ETERNITY The results obtained are shown below: Results Methodology Objective Introduction Conclusion References 1. Study the theories and principles concerning the waste incineration 2. Selection of the target city by collecting all of available data 3. Determination of the preliminary design and technologies comparison of waste incineration 4. Simulation of the preliminary process design 5. Detailed design of the MSW incineration process and equipment Waste capacity 720 Ton/day of MSW Heating value of 9.6 MJ/kg Plant annual availability 8640h Total Electricity Generation 18 MW Net electricity output 10 MW Solid Residuals Bottom ashes: 1.5 Ton/day Fly ashes: 17.5 Ton/day Reagent consumption in flue gas treatment Water: about 425.03 cubic meter/day Ammonia 25%: 21.1 Ton/day Stack Emission characteristics Flow rate: 180,900 cubic meter/hour Stack gas temperature: 160°C Stack Height: 72 m Stack gas velocity: 18 m/s The methodologies to do the study and design are: Since November 1988, landfill “Doña Juana” has been the only solution for the Bogotá’s MSW disposal. Taking into account the limitations of the landfill and Bogotá’s target in MSW reduction; an incineration plant is proposed in this study. The incineration plant will reduce 9% of the total MSW generated in 2016 which has capacity of 30 Ton/h and covers three areas 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 Fig 1. Component Analysis Fig 2.
