This research presents an energy recovery from municipal solid waste (MSW) in Port Harcourt metropolis, Rivers State. The main focus is to investigate the conditions of renewable municipal solid waste (MSW) generated in Port Harcourt and to properly evaluate the minimum quantity of electricity that can be made from the MSW on a daily basis using the combustion pathway. The data used to assess the availability of the fuel (MSW) were obtained from waste dumpsites controlled by Rivers State Waste Management Agency (RIWAMA). The various parameters for the combustion chamber, which utilizes mass combustion in stoker crate furnace, were selected for the amount of MSW generated in Port Harcourt and operated at different steam saturation pressures within (20 – 45) bar, with a fuel consumption rate of 11.88kg/s. Analytical tools were used to analyze the combustion characteristics of the chemical compositions of the waste generated. The result revealed that for every kg of MSW combusted, 6.63kg of air is required for complete combustion generating an optimum flue gas mass flow of 87.63kg/s and temperature of 400oC. The flue gas of mass flow ranging from 70.37kg/s - 87.63kg/s produce steam within the range of 9.2134kg/s – 9.8482kg/s at different steam pressures and stack temperatures. These indicate a resultant average net power output of 4.47MW of electricity when retrofitted to a steam turbine plant. This work thus showed that there are huge potentials in generating electrical energy from MSW in Port Harcourt, employing appropriate technology.

Abstract:

This research presents an energy recovery from municipal solid waste (MSW) in Port Harcourt metropolis, Rivers State. The main focus is to investigate the conditions of renewable municipal solid waste (MSW) generated in Port Harcourt and to properly evaluate the minimum quantity of electricity that can be made from the MSW on a daily basis using the combustion pathway. The data used to assess the availability of the fuel (MSW) were obtained from waste dumpsites controlled by Rivers State Waste Management Agency (RIWAMA). The various parameters for the combustion chamber, which utilizes mass combustion in stoker crate furnace, were selected for the amount of MSW generated in Port Harcourt and operated at different steam saturation pressures within (20 – 45) bar, with a fuel consumption rate of 11.88kg/s. Analytical tools were used to analyze the combustion characteristics of the chemical compositions of the waste generated. The result revealed that for every kg of MSW combusted, 6.63kg of air is required for complete combustion generating an optimum flue gas mass flow of 87.63kg/s and temperature of 400oC. The flue gas of mass flow ranging from 70.37kg/s - 87.63kg/s produce steam within the range of 9.2134kg/s – 9.8482kg/s at different steam pressures and stack temperatures. These indicate a resultant average net power output of 4.47MW of electricity when retrofitted to a steam turbine plant. This work thus showed that there are huge potentials in generating electrical energy from MSW in Port Harcourt, employing appropriate technology.
